Professor Brian Keating and scientists at four other universities announced they've found circumstantial evidence of the spark that caused the Big Bang 13.78 billion years ago. Read More

Professor Brian Keating is among the cosmologists in the consortium that reported a detection in curling patterns in the faint glow of the universe's oldest light that appear to be traces left by cosmic inflation, an exponential expansion of the universe thought to have occurred fractions of a second after the Big Bang. The evidence comes from observations made by BICEP2, a telescope that operated at the South Pole for three years, continuously scanning the sky for variations in the cosmic microwave background, or CMB.

Dusan Keres and collaborators convincingly show that large amount of energy released by individual stars has dramatic consequences for the evolution of galaxies. For a long time astrophysicists attempted to understand why galaxies contain only a small fraction of the material available in the universe. In a new set of realistic supercomputer models of galaxies in our universe called FIRE (The Feedback in Realistic Environments) multi-university collaboration convincingly showed that this lack of cosmic material in galaxies is related to energetic events that closely follow formation of stars. Energy released by individual young stars substantially affects the evolution of galaxies and pushes large quantities of galactic gas into the inter-galactic medium preventing its accumulation in galaxies.

CASS scientists Professor Kim Griest and Agnieszka Cieplak, Kim's graduate student and now a postdoc at Brookhaven National Lab, have used data from NASA's Kepler planet finder spacecraft to do something that mission was never intended by its designers to do: look for primordial black holes. They did not find any, but they did close an important black hole mass window in which these objects could have been a very significant portion of the dark matter. In doing this study they have pioneered a new technique in the search for primordial black holes. Their work is published in the prestigious journal Physical Review Letters ("New limits on primordial black hole dark matter from an analysis of Kepler source microlensing data", Kim Griest, Agnieszka M. Cieplak, and Matthew J. Lehner) and has been "Highlighted" by the editors of that journal, an honor implying the special significance of this work. Click on 'Read More' for link to synopsis of work.

Astronomers have spotted a galaxy that is igniting new stars faster than ever seen before. Measurements from several instruments show that gas in this galaxy is condensing to form stars close to the maximum rate thought possible. “What is unique about this particular galaxy is that it is forming stars so rapidly with such a tiny supply of gas,” said Aleksandar Diamond-Stanic, a fellow at the University of California’s Southern California Center for Galaxy Evolution who helped make the discovery. A team of nine astrophysicists recently reported the finding in Astrophysical Journal Letters. Read More

Professor Alison Coil is the co-PI of a major new faint galaxy redshift survey being undertaken at the 10-meter Keck I Telescope on Mauna Kea, Hawaii. The MOSFIRE Deep Evolution Field (MOSDEF) survey will exploit the new capabilities of a recently-completed multi-object near infrared spectrograph called MOSFIRE, built at the UCLA Infrared Laboratory. Using this new spectrograph, the MOSDEF survey will target 2,000 extremely distant galaxies, lying 9 to 11.5 billion light years away. With these data, the team will obtain rest-frame optical spectra to study the stellar and gaseous content of very young galaxies, charting galaxy evolution when the Universe was only 2-4 billion years old. Professor Coil will study in particular the growing supermassive black holes in these distant galaxies. The MOSDEF team has been awarded a total of 47 observing nights on the Keck I telescope for the survey, which will take four years to complete and will result in more than an order of magnitude improvement over existing surveys. MOSDEF is a UC-wide collaboration; additional co-PIs include Alice Shapley (UCLA), Mariska Kriek (UCB), Naveen Reddy (UCI), Brian Siana (UCI), and Bahram Mobasher (UCI). Read More

Each year, a shortlist of ten papers is nominated for the prize. These are papers of the highest scientific standard, published in the journal volume from two years previous to the award year. Nominations are based on citation record and recommendations by the Board of Editors. The Board then votes by secret ballot to determine which of these papers has made the largest scientific impact.

The award was presented at the 2012 Fusion Energy Conference in San Diego.

CASS Director and Distinguished Professor of Physics George Fuller has been selected to receive the 2013 Hans A. Bethe Prize. The prestigious award is given annually by the American Physical Society to "recognize outstanding work in theory, experiment or observation in the areas of astrophysics, nuclear physics, nuclear astrophysics, or closely related fields." The prize, which was established to honor Bethe, a renowned nuclear physicist at Cornell University, consists of $10,000 and a certificate citing the contributions made by the recipient. Fuller was cited for "outstanding contributions to nuclear astrophysics, especially his seminal work on weak interaction rates for stellar evolution and collapse and his pioneering research on neutrino flavor-mixing in supernovae." He will formally receive his award at a special session of the society's April 2013 meeting in Denver.

Fuller has focused much of his recent research at CASS on the physics of the mysterious and ghostlike particles in the universe known as neutrinos, which hold the keys to physicists' improved understanding of cosmology, exploding stars called supernovae, and the origin of the elements. Fuller and his research group at UC San Diego have been calculating how neutrinos likely changed their "flavors" in the early universe, how they do so now within supernovae and how this process affects the synthesis of elements within stars--a process astrophysicists call nucleosynthesis.

Fierce galactic winds powered by an intense burst of star formation may blow gas right out of massive galaxies, shutting down their ability to make new stars. Sifting through images and data from three telescopes, a team of astronomers led by CASS Postdoctoral Fellow Aleksandar Diamond-Stanic found 29 objects with outflowing winds measuring up to 2,500 kilometers per second, an order of magnitude faster than most observed galactic winds. Read More

Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events. Physics grad student JJ Cherry models stellar explosions, including a type called a core-collapse supernova. As these stars run out of fuel, their cores suddenly collapse to form a neutron star, which quickly rebounds sending seas of neutrinos through the surrounding stellar envelope and out into space. Prof. Fuller leads the neutrino-modeling research group and is a co-author of the paper. Read More

Formation of disk-like galaxies observed in our cosmic neighborhood is a long standing problem in astrophysics. Recently a team of scientists applied new computational method to model formation and evolution of a large number of galaxies from the times when our Universe was very young to present. These new computer simulations provide much better accuracy than previous models and for the first time produced a large population of galaxies with extended gaseous disks similar to the ones in in our neighborhood. The team from CASS-UCSD, Harvard-Smithsonian CfA and HITS Institute in Germany described their work in three recently accepted publications; UCSD Assistant Professor of Physics Keres is the leading author on one of these publications.
