The idea that dark matter is made of primordial black holes is very old but has always been in the backwater of particle physics.
So, let us do a recap of what was the situation for the strength of the signals for the decays of the Higgs particle.
From the table one can see that the signal strengths for decays in ATLAS are somewhat beyond unity while in CMS these are practically unity for but, more interestingly, 0.85 for .
At LHCP2016 new data have been presented from the two collaborations, at least for the decay.
This result is striking per seA as shows a tendency toward a decreasing value when, in precedence, it was around unity. I was travelling back from Cambridge on the train yesterday afternoon when I saw the announcement that the Advanced LIGO team had found a second gravitational wave source. This signal, code-named GW151226, like the previous one, appears to be from a black hole binary coalescence but it involves two black holes of rather lower masses (about 14 and 8 solar masses respectively).
Well, this conversation (for the book) takes place in a (famous) railway station, so it would be neglectful of me to not have people scurrying around and so forth. This is a screen shot (literally, sort of - I just pointed a camera at it) of a detailed large panel in progress. SpaceX placed two communications satellites into orbit today, but the company's attempt to go four-in-a-row on first stage drone ship recoveries fell short.
A guide to interesting stuff going on in space science, space exploration, and space advocacy. Curiosity is at a turning point in its mission to Mount Sharp, both literally and figuratively. Among the sessions I attended yesterday, I really liked the one on robustness and model mispecification. The first session on Wednesday at 228th AAS Meeting was the Newton Lacy Pierce Prize Lecture by Heather Knutson (California Institute of Technology).
One of her first points is the well-known idea that the Solar System is an oddball, compared to the exoplanet systems we have found so far: most of these systems contain hot Jupiters and mini-Neptunes at very close-in orbits around their host stars.
On December 26th 2015, LIGO detected its second full-fledged gravitational wave event, dubbed GW151226 (the numbers signify the date it was detected).
This discovery further solidifies this nascent field into astronomy, and has given astronomers a new sense to explore the Universe. Our zoo of stellar-mass black holes, including the 2 confirmed LIGO event, the 1 LIGO candidate, and indirect evidence from X-ray binaries. Star Formation in a Range of Environments (by Benny Tsang)David Cook began our morning star formation session with his work on the connection between the slopes of luminosity functions for star-forming regions and the host-galaxy properties.
Kaveh Vasei took us on his journey estimating the escape fraction of Lyman continuum photons from galaxies. Philip Hopkins then continued the theoretical discussion and showed that enough ionizing photons for cosmic reionization could be obtained if we consider binary stars. Following this morninga€™s exciting press conference, Gabriela GonzA?lez, spokesperson for the LIGO Scientific collaboration, gave the Kavli Foundation Plenary Lectureship. GonzA?lez opened the plenary by digging a little further into the physics of LIGO detections. Our ability to localize gravitational-wave detections currently relies on the timing of the observations: noting the difference in time between when the signal passes the LIGO Livingston and LIGO Hanford detectors (on the scale of 10 ms) can give us a broad sense of where in the sky the signal came from.
Gonzalez: the addition of Virgo will significantly improve our ability to localize the sources. As a final note, GonzA?lez pointed out that detections by ground-based gravitational-wave interferometers are only the start of gravitational-wave astronomy. For a second time, scientists from the LIGO and Virgo collaborations saw gravitational waves from the merger of two black holes. Scientists from the LIGO and Virgo collaborations announced today the observation of gravitational waves from a set of merging black holes.
This follows their previous announcement, just four months ago, of the first ever detection of gravitational waves, also from a set of merging black holes.
The detection of gravitational waves confirmed a major prediction of Albert Einsteina€™s 1915 general theory of relativity. Gravity is by far the weakest of the known forces, but if an object is massive enough and accelerates quickly enough, it creates gravitational waves powerful enough to be observed experimentally. LIGO consists of two huge interferometers in Livingston, Louisiana, and Hanford, Washington. Scientists on the Virgo collaboration have been working with LIGO scientists to analyze their data.
With this second observation, a€?we are now a real observatory,a€? said Gabriela Gonzalez, LIGO spokesperson and professor of physics and astronomy at Louisiana State University, in a press conference at the annual meeting of the American Astronomical Society. On Christmas evening in 2015, a signal that had traveled about 1.4 billion light years reached the twin LIGO detectors.
The black holes were 14 and eight times as massive as the sun, and they merged into a single black hole weighing 21 solar masses.
The LIGO detectors saw almost 30 of the last orbits of the black holes before they coalesced, Gonzalez said during the press conference.
Additional detectors will make it possible not only to find evidence of gravitational waves, but also to triangulate their origins. On its own, LIGO is a€?more of a microphone,a€? capturing the a€?chirpsa€? from these events, Gonzalez said. The next event scientists are hoping to a€?heara€? is the merger of a pair of neutron stars, said Caltecha€™s David Reitze, executive director of the LIGO laboratory, at the press conference. Whereas two black holes merging are not expected to release light, a pair of neutron stars in the process of collapsing into one another could produce a plethora of observable gamma rays, X-rays, infrared light and even neutrinos.
In the future, gravitational wave hunters hope to be able to alert astronomers to an event with enough time and precision to allow them to train their instruments on the area and see those signals.
Therea€™s additional news from LIGO (the Laser Interferometry Gravitational Observatory) about gravitational waves today. The signal is not so a€?brighta€? as the first one, so it cannot be seen by eye if you just look at the data; to find it, some clever mathematical techniques are needed. It is interesting that we already have two, maybe three,A mergers of large black holesa€¦ and no mergers of neutron stars with black holes or with each other, which are harder to observe.
With a stellar lineup of speakers to talk about current and future prospects of cosmology and its limits (or lack thereof), the first session kicked off with talks by Risa Wechsler, Joseph Silk, and Sean Carroll (his talk on Multiverses is described below, by Nathan Sanders). The CMB measurements, Big Bang Nucleosynthesis estimates and galaxy clustering statistics all contribute to locking down the description of our universe. By invoking the anthropic principle, Silk pointed out that perhaps multiverses could offer a potential solution to certain causes of concern in our current models. Slotted into the a€?contrariana€? slot of this special session on the limits of cosmology, Sean Carroll (Caltech) made a powerful argument for the normalcy of the multiverse prediction of inflationary and other theories of cosmology. Surprisingly, Carroll also comments that evidence can include both data and theory, specifically new interpretations of old ideas and new predictions. Jo Bovy (Toronto) spoke about a bevy of recent discoveries by the APOGEE team, which has collected half a million spectra of red giant stars throughout the Milky Way disk. Tuesday afternoon brought another press conference to the AAS 228th meeting, this one taking us beyond the benign realms of planets, stars, and galaxies to Dark Skies, Aliens, and the Multiverse. Next, Evan Solomonides, an undergraduate student at Cornell University, presented a probabilistic analysis of the Fermi Paradox, the famous statement that asserts that if life is common in the Universe (as many believe), we should have detected it by now. Finally, cosmologist and science communicator extraordinaire Sean Carroll zoomed the focus out beyond the galaxy, beyond the observable universe, to the basic question of what it even means to do science in a multiverse.
In this era of big data, our ability to classify the plethora of celestial objects we detect is essential to our science. Imre Bartos moved away from classification to discuss potential electromagnetic counterparts to black hole-black hole mergers. Tomomi Otani explained how we can look for planets and other companions around post main sequence stars, or stars which have finished burning hydrogen.
The second session of this forum constituted a series of talks aimed at setting the premise for our current understanding of the universe, and the very story of how cosmology came to be a science. Richard Dawid followed this up with a new philosophical theory of science, putting an emphasis on non-empirical confirmation of theories, and tracking evolution of credence (e.g. If you put 3 cosmologists is a room, two of them will say the 3rd doesna€™t understand Malmquist bias. Plenary Session a€“ Things That Go Bump in the Night: The Transient Radio Sky (by Susanna Kohler)This afternoon plenary was given by Dale Frail of the National Radio Astronomy Observatory, who injected some pop culture into our day by introducing radio transients as some of the nighta€™s terrors that Game of Thrones warned us about.
In general, Frail emphasized, the radio sky is quiet; radio transients are actually quite rare. Frail gave an overview of what we currently know about the radio transients that wea€™ve observed a€” including where we find them, what energies they span within the radio band, and what timescales they vary on.
He also discussed the different strategies used to learn more about the transient radio sky: wea€™re generally faced with the choice to either a€?be a cartographera€? by using all-sky surveys to search for new transients, or a€?be a buccaneera€? by strategically following up on survey leads to localize and identify transient sources.
Frail argued that the way forward is to combine these strategies: use all-sky radio surveys coupled with rapid multi-wavelength follow-up. One of the best ways to learn about exoplanets is by carefully studying planets much closer to home. Several different processes are responsible for Mars losing parts of its atmosphere to space. Beyond the detailed physics and chemistry illustrated above, the differences in Marsa€™ atmosphere as a function of the Suna€™s behavior are a challenge to observe because the Sun is experiencing a quiet solar maximum with relatively few coronal mass ejections.

The WIMP or asymmetric dark matter paradigms are preferred for several reasons such as calculability, observational opportunities, and a more direct connection to cherished theories beyond the Standard Model. We all have seenA the history unfolding since the epochal event on 4 July 2012 where the announcement of the great discovery happened.
Data gathered on 2015 seem to indicate a further state at 750 GeV but this is yet to be confirmed.
As I pointed out here, there is a curious behavior of the strengths of the signals of Higgs decay in and some tension, even if small, appeared between ATLAS and CMS results. If the state at 750 GeV should be confirmed, as the spectrum given by the exact solution of the Higgs sector is given by an integer multiplied by a mass, this would be at . Then, summer conferences will start and, paraphrasing Coleman: God knows, I know and by the end of the summer we all know. Actually, I knew this one was coming but I had forgotten that it was to be announced at the American Astronomical Society meeting thata€™s happening now in San Diego. After three days in Cambridge as External Examiner, I now have to chair our undergraduate finalist examination board here at Sussex. Having drilled at three sample sites in 7 weeks, the rover took a left turn, changing its trajectory from a generally westward driving path to a southward one. Especially the talk by Steve McEachern on Bayesian inference based on insufficient statistics, with a striking graph of the degradation of the Bayes factor as the prior variance increases. This morning LIGO reporting on the results from its first observing run and announced the confirmation of a second gravitational wave event - GW151226! A team of astrobiters isA attending the conference this year, and we will report highlights from each day here on astrobites. This talk featured a broad range of research efforts on exoplanets, with the main focus on how we study the composition of their atmospheres, and how multi-body interactions carve the structure of the planetary systems we observe. Moreover, even when studying their transmission spectra, it is difficult to know the exact composition of their atmospheres.
The next observing run of LIGO will commence later in 2016 and will be more sensitive due to system upgrade, increasing the rate at which LIGO should detect these types of astrophysical events. A moderate-strong trend was found: galaxies with higher star formation rate surface densities (the star formation rate per area projected on the sky) tend to have flatter luminosity functions. He argued that the commonly used indirect methods in determining the escape fraction should only be interpreted as upper limits, and showed us the highest-resolution image of Lyman continuum leakers so far.
The idea is that material transfer within binary systems could extend the lifetimes of massive stars, thereby allowing them to produce enough ionizing photons before they die.
Though the Kavli lecture usually opens the AAS meeting, it was moved this week to accommodate the schedule for LIGOa€™s big announcement today!
She described how the detectors work, pointing out that theya€™re designed to detect a strain of 1 part in 1021. Our ability to localize will significantly improve when future detectors like Virgo (Europe), LIGO-India, and KAGRA (Japan) come online within the next decade. There were actually three significant gravitational-wave triggers in the first science run; the third has an 85% probability of being astrophysical, compared to the nearly 100% probability of the two official detections.
Future observatories and missions (like eLISA, and improved-sensitivity pulsar timing arrays) will expand the search for gravitational waves to different frequency ranges. Einstein posited that every object with mass exerts a gravitational pull on everything around it. LIGO, or Laser Interferometer Gravitational-wave Observatory, caught the two sets of gravitational waves using lasers and mirrors. The distant merging of two black holes caused a slight shift in the fabric of space-time, equivalent to changing the distance between the Earth and the sun by a fraction of an atomic diameter.
That might sound like a lot, but these were relative flyweights compared to the black holes responsible for the original discovery, which weighed 36 and 29 solar masses. The black holes had 14 solar masses and 8 solar masses, and merged into a black hole with 21 solar masses, emitting 1 solar mass of energy in gravitational waves. It seems there really are a lot of big black holes in binary pairs out there in the universe. When LIGO starts its next run, six months long starting in September, the improvements over last yeara€™s run will probably give a 50% to 100% increase in the rate for observed mergers. Highlights include deep discussions on the multiverse, the limits of scientific cosmology, and the atmospheric loss of Mars analyzed by the MAVEN explorer. Risa set the stage with an elaborate description of the current accepted facts in the era of precision cosmology including the standard model of concordance cosmology, described by seven parameters and an accepted Lambda-CDM paradigm (with a cosmological constant and cold dark matter). She emphasized on the tensions between different probes to measure expansion rate H0 of the universe, and small scale predictions of cold dark matter simulations, but she is hopeful that these shall be resolved eventually. The future looked good, and according to Silk, a better characterization of non-gaussianities using powerful simulations and precise CMB measurements is the way to go.
While other scientists, including earlier speakers in the session, suggested that the intense difficulty of collecting data directly testing the multiverse prediction disqualifies it as a a€?scientifica€? theory, Carroll argued that this is no different from the reality of the scientific process applied generally.
For example, Einstein did not make new observations of the precession of Mercury to lend credence (in the scientific sense) to his then-new theory of general relativity. A Bovy emphasized APOGEEa€™s unprecedented scope, covering close to half of the Milky Way disk and ranging ~10 kpc in radius, rather than the tiny neighborhood around the sun that most historical stellar surveys have probed. The basic takeaway from his work is that while wea€™ve been sending powerful radio transmissions into space for the last 80 years, the volume of space reached by these transmissions is incredibly insignificant (perhaps 10 parts per million) compared to the size of our galaxy. Carroll argued that even if a scientific theory is unable to be directly tested, it should not be automatically discarded as impossible or irrelevant.
Gideon Bass began this session by discussing his work in using machine learning to classify Kepler variable stars.
Specifically, stellar mass black holes near the center of galaxies are more likely to collide within only a million years due to friction. One of the six targets (named PG-1219+534) from her survey in fact has a planet which has survived its host stara€™s drastic expansion as it reached the red giant branch. Matt Stanley gave us an extraordinary tour of the last 150 years of scientific tendencies to create models of the universe. Radio transients are an incredibly broad category, spanning sources that can vary on fraction-of-a-second timescales (like pulsars) to year-long timescales (like jets from active galactic nuclei). But the list of potential radio transients, while including many known sources, also pushes into more speculative territory.
This combines the serendipitous element of surveys a€” the ability to find things we werena€™t necessarily searching for, such as the first pulsar signal ever detected a€” with the higher-precision tools needed to identify what wea€™re looking at. Shannon Curry emphasized this throughout her presentation about Marsa€™ atmosphere, which was motivated by the fact that Mars used to be a warmer, wetter planet. Because Mars is a relatively small planet, it has had a difficult time holding onto its atmosphere over the history of the Solar System.

Would you like to learn how to write copy that sells like crazy, but doesn’t sound sleazy or pushy?
But in the recent months there has been more interest, triggered in part by the LIGO observations of black hole binary mergers. Anyway, both ATLAS and CMS see this bump in the data and this seems to follow the story of the discovery of the Higgs particle. Indeed, ATLAS seemed to have seen more events than CMS moving these contributions well beyond the unit value but, as CMS had them somewhat below, the average was the expected unity agreeing with expectations from the Standard Model. In order to see if the scenario provided from the exact solution of the Higgs sector is in agreement with data, these should be confirmed from run II and those from ATLAS should go down significantly. The value seen is again in agreement with that given in the exact solution of the Higgs sector.
Together with the production strengths, if further data will confirm them, the proper scenario for the breaking of electroweak symmetry is exactly the one described by the exact solution. It may not look visually as clear as the first source, GW150914, which involved black holes with masses in the region of 30 solar masses, but ita€™s a clear detection and ita€™s also interesting that the models suggest that at least one of the black holes has a significant spin. I was wondering last night how long it will take before every individual discovery like this is reported. I sadly had no time to grab a picture of the graph, which compared this poor performance against a stable rendering when using a proper summary statistic. Knutson and her group a€” The Friends of Hot Jupiters a€” study systems with close-in gas giants and their frequency of binary companions, which are supposed to be the main culprits causing gas-giant migration. In addition, more detectors will be joining the network of gravitational wave observatories over the next few years, which will further constrain the location at which these events occur in the cosmos and increase the likelihood of detecting an electromagnetic counterpart to a gravitational wave event.
It was interpreted as the result of increased star formation efficiencies in high-density environments, which led to a large number of bright regions. David Guszejnov then led the first theoretical talk on modeling star formation using semi-analytical models a€“ an approach between full-blown numerical simulations and pen-and-paper calculations. This is roughly the same as measuring if the Earth-Sun distance changed by the size of a single atom! The fact that there have been so many detections already a€” despite the fact that LIGO is only at 40% of its design sensitivity a€” suggest that we can expect many more to come!
When a massive object moves, its pull changes, and that change is communicated in the form of gravitational waves. At the end of each arm, the split beams bounce off of mirrors and return to recombine in the center. In contrast to the September event, which was short and showed just a few orbits before the merger, in this event nearly 30 orbits over a full second are observed, making more information available to scientists about the black holes, the merger, and general relativity.

If it is really due to gravitational waves, it would be merging black holes againa€¦ midway in size between the September and December eventsa€¦ but it is borderline, and might just be a statistical fluke. Incidentally, the question of whether they might form the dark matter of the universe has been raised; ita€™s still a long-shot idea, since there are arguments against it for black holes of this size, but seeing these merger rates one has to reconsider those arguments carefully and keep an open mind aboutA the evidence.
More detectors will allow scientists to know where on the sky the merger took place, which then can allow normal telescopes to look for flashes of light (or other forms of electromagnetic radiation) that might occur simultaneously with the mergera€¦ as is expected for neutron star mergers but not widely expected for black hole mergers.
Joe Silk followed this up with his interpretation of trying to understand our place in the universe and placing limits on different parameters and scales that we measure, ranging from star masses to dark energy scale estimates. He combats the absolutist interpretation of Karl Poppera€™s writing on demarcation, which implies that only imminently-falsifiable theories qualify as a€?scientific.a€? Instead, he points us to abduction as the fundamental motive of science, the idea that we seek to move towards the model that best explains the available evidence, closely related to Bayesa€™ theorem. A Instead, he applied his theory for the first time to the orbit of Mercury and demonstrated that it explains existing facts.
The score incorporates the measured radiance (brightness), taking into account the number of people, the number of housing units, and the community area, and is then normalized to be between 1 and 100.
If similar civilizations to ours have cropped up across the Milky Way and had even significantly longer timescales over which to send out signals, it is actually not surprising that we havena€™t seen them yet, simply by virtue of the vastness of space. One cannot definitively prove that beyond the observable universe lie regions of space that have vastly different physical properties or cosmologies a€“ in other words, the existence of a multiverse a€“ and so this possibility should at least be philosophically considered by scientists, and the potential influences that the multiverse would have on the observable universe should be looked for. Bass ties together many machine learning algorithms to create a a€?Frankensteina€? method to maximize accuracy.
Finally, Paula Szkody explained the exotic light curves of cataclysmic variables found with K2. John Tyndall, James Clark Maxwell, Ernst Mach all joined the party, as we moved towards the Friedman-Lemaitre-Robertson-Walker model and Einsteina€™s tweaks to his field equations in General Relativity.
Virginia Trimble brought the afternoon discussion to a conclusion by discussing a very unique empirical observation: whenever a community has come at a juncture where the choice has been between one or many, finite or a€?infinitea€™ (in a non-mathematical sense!), the latter has always won the debate. Interesting examples include the mysterious Fast Radio Bursts (FRBs) discussed in yesterdaya€™s plenary by Maura McLaughlin, and electromagnetic counterparts to gravitational waves.
The Mars Atmosphere and Volatile Evolution orbiter (MAVEN) arrived at Mars in September 2014 and has been collecting many kinds of data about the Martian atmosphere ever since. Neutral particles, ionized particles, and even water vapor all find unique ways to escape the grip of Marsa€™ gravity. Mars serves as an excellent analog for exoplanet hydrogen loss and can tell us whether similarly-sized planets are likely to have the same fate. But wait a€“ therea€™s morea€¦ This is fascinating conversationA ended up being so far-ranging, we had to make it two episodes.

In the first observed event, the mass of each of the black holes was estimated at around 30 solar masses. What is still there is our need of a deep understanding of the Higgs sector of the Standard Model. The strength of the signals is essential to understand if the propagator of the Higgs field is the usual free particle one or has some factor reducing it significantly with contributions from higher states summing up to unity. The value 0.85 is really in agreement with the already cited exact computations from the Higgs sector but, within the error, in overall agreement with the Standard Model. Of course, this should be obviously true but an experimental confirmation is essential for a lot of reasons, last but not least the form of the Higgs potential that, if the numbers are these, the one postulated in the sixties would be the correct one. The same thing happened with the first few extra-solar planets but now that we have thousands, ita€™s only a subset a€“ those that might plausibly be similar to Earth a€“ that get press attention. It clearly relates to our work on ABC model choice, as well as to my worries about the Bayes factor, so this explains why I am quite excited about this notion of restricted inference. They found that approximately half of the observed systems have long-distance companions, providing strong validation of the migration scenario. Though less visible by eye in the data, sophisticated search algorithms that match theoretically-produced templates of the gravitational waveform were able to extract it from the data and build up enough statistical confidence to declare it as a detection. Next, Daniel Carson presented his dissertation work on the observations of nuclear star clusters in disk galaxies.
The advantage of such an approach is that you could explore different star formation models (with or without feedback) very quickly.
An asymmetric distribution of nitrogen-bearing species was found, which could be due to disk fragmentation on unresolved scales and the formation of multiple sources with different ages. If a gravitational wave passes through the laser beams as they travel, it stretches space-time in one direction and compresses it in another, creating a mismatch between the two.
He acknowledged that we may never collect enough evidence for our credence in the multiverse to converge to one, and yet it may definitely be true. In the same way, we may add or remove credence from the multiverse theory even without newly collected measurements on directly testable predictions.
A In particular, they have shown that the star formation and chemical evolution history of the Galaxy seems to be remarkably constant throughout the disk.A However, the radial migration of stars, which follows a non-circular orbit across the Milky Waya€™s spiral structure, causes mixing that makes the distribution of stellar parameters look uneven. A LANI can be used to assess where additional efforts are needed to improve energy efficiency and reduce light pollution, as well as to track changes in infrastructure and population over time. Solomonides predicts that it will be about 1500 years before it is probabilistically favorable to detect extraterrestrial civilizations, based on these assumptions. At higher energies, Saeqa Vrtilek discussed the use of color-color-intensity diagrams in X-ray wavelengths to classify objects such as cataclysmic variables, black holes and neutron stars. This odd binary undergoes eclipses about once every quarter of a century, when a dusty disk passes in from of the primary star, as shown below.
Stanley gave due credit to the Steady State Cosmology a€?movementa€™, since it was using Popperian falsifiability that Hermann Bondi and Fred Hoyle established the rules of how a theory of the universe should look like.
Whether we talk about a small Ptolemaic geocentric universe or a larger-than-life Copernican heliocentric solar system, the Milky way being the only galaxy vs.
In addition, the variable effects of the Solar wind and other space weather affect what kind of material is lost. The show includes interviews with well-known experts like Michael Hyatt, Jeff Goins, Dan Miller, Cliff Ravenscraft, Michael Stelzner, Amy Porterfield, Donald Miller, and many others.
Instead you ought to say, a€?If the Lord wills, we shall live and do this or that.a€? But now you boast in your arrogance.
Trust Him, because in the final analysis, He’s the only one you can totally trust, every time.
While such a system may well be of boring astrophysical origin, it is somewhat unexpected because typical black holes we come across in everyday life are either a bit smaller (around one solar mass) or much larger (supermassive black hole in the galactic center). Quite recently, LHC restarted operations at the top achievable and data are gathered and analysed in view of the summer conferences. The reason is that, in run I, gathered data were not enough to reduce the error bars to such small values to decide if Standard Model wins or not. In this case, the observed state at 125 GeV would be just the ground state of a tower of particles being its excited states.
This seems to point toward on overestimated number of events in ATLAS but a somewhat reduced number of events in CMS, at least for decay. This is the most shocking result: They see a significant reduced set of events and the signal strength they obtain isA now alignedA to the one of CMS (see Strandberga€™s talk at page 11).
An other important reason is that coupling with other matter does not change the spectrum of the theory in a significant way.
At the current rate of discovery gravitational-wave sources may well become quite common over the next few years. In this session, Chris Holmes also summarised his two recent papers on loss-based inference, which I discussed here in a few posts, including the Statistical Science discussion Judith and I wrote recently. The system was estimated to have merged at a distance of 1.4 billion light-years, and, due to its lower mass, stayed in LIGOa€™s detection band for a full second (5 times longer than the more massive GW150914). The semi-analytical models with feedback reproduced observables such as the slope and turnover of the initial mass function well, and this technique can also further the understanding of binary-star formation. A While he puts his own credence in the multiverse at a€?about 50%,a€? Carroll concludes that we should not reject the possibility of the multiverse out of hand solely on the basis of philosophical arguments. A Bovy also emphasized the importance of open science, sharing data and code related to their work. On the other hand, if the dark matter halo were made of black holes, scattering processes would sometimes create short-lived binary systems. As I showed recently, this is not physics beyond the Standard Model, rather is obtained by solving exactly the quantum equations of motion of the Higgs sector (see here). Knutson speculates that wide binaries have more massive disks, which in turn produce more gas giants, populating our surveys with such planets.
Stellar population modeling also revealed the star formation histories and stellar masses of the clusters. A Like all SDSS data, the APOGEE spectra have been released publicly, and all their software pipelines and stellar models have also been made public. Hence Trimble asks, then who are we to stop at a universe, with existing ideas of a multiverse!
And they’ll even send you photos of it so you can breathe easy that ita€™s on its way. Assuming a significant fraction of dark matter in the universe is made of primordial black holes, this paper estimated that the rate of merger processes is in the right ballpark to explain the LIGO events.Primordial black holes can form from large density fluctuations in the early universe. So, several theoretical proposals for the Higgs sector still stand up and could be also confirmed already in August this year.
This is done considering the other fields interacting with the Higgs field just a perturbation. Actually from my point of view the really interesting challenge is to make full use of the low signal-to-noise detections that are probable sources but with some uncertainty.
The stellar mass surface density of IC342 was measured to lie above the theoretical maximum set by stellar feedback. A Coming next is an APOGEE-2 survey of the Southern sky, a copy of the instrument to be installed at the DuPont telescope in Chile.
On the largest observable scales the universe is incredibly homogenous, as witnessed by the uniform temperature of the Cosmic Microwave Background over the entire sky. I hope to write a blog post soon about how Bayesian methods can help a great deal with that. However on smaller scales the primordial inhomogeneities could be much larger without contradicting observations.
A From the fundamental point of view, large density fluctuations may be generated by several distinct mechanism, for example during the final stages of inflation in the waterfall phase in the hybrid inflation scenario. While it is rather generic that this or similar process may seed black hole formation in the radiation-dominated era, severe fine-tuning is required to produce the right amount of black holes and ensure that the resulting universe resembles the one we know.All in all, it's fair to say that the scenario where all or a significant fraction of A dark matter A is made of primordial black holes is not completely absurd. Moreover, one typically expects the masses to span a fairly narrow range.A Could it be that the LIGO events is the first indirect detection of dark matter made of O(10)-solar-mass black holes? A Black holes sloshing through the early dense universe accrete the surrounding matter and produce X-rays which could ionize atoms and disrupt the Cosmic Microwave Background. In astrophysics, however, not only signals but also constraints should be taken with a grain of salt.
A In this particular case, the word in town is that the derivation contains a numerical error and that the corrected limit is 2 orders of magnitude less severe than what's shown in the plot. Moreover, this limit strongly depends on the model of accretion, and more favorable assumptions may buy another order of magnitude or two.
All in all, the possibility of dark matter made of A primordial black hole in the 10-100 solar mass range should not be completely discarded yet. Another possibility is that black holes make only a small fraction of dark matter, but the merger rate is faster, closer to the estimate of this paper.Assuming this is the true scenario, how will we know? Direct detection of black holes is discouraged, while the usual cosmic ray signals are absent. Instead, in most of the mass range, the best probes of primordial black holes are various lensing observations. These are strong radio signals of (probably) extragalactic origin and millisecond duration.
The radio signal passing near a O(10)-solar-mass black hole could be strongly lensed, leading to repeated signals detected on Earth with an observable time delay. In the near future we should observe hundreds of such repeated bursts, or obtain new strong constraints on primordial black holes in the interesting mass ballpark. A When more statistics is accumulated, we will be able to say something about the spatial distributions of the merger events.
Primordial black holes should be distributed like dark matter halos, whereas astrophysical black holes should be correlated with luminous galaxies. Also, the typical eccentricity of the astrophysical black hole binaries should be different.
