| 4 August 2017 : Primordial Black Holes May Have Helped to Forge|
Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis.
As the late Carl Sagan once put it: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff.”
But what about the heavier elements in the periodic chart, elements such as gold, platinum and uranium?
Astronomers believe most of these “r-process elements”—elements much heavier than iron—were created, either in the aftermath of the collapse of massive stars and the associated supernova explosions, or in the merging of binary neutron star systems.
“A different kind of furnace was needed to forge gold, platinum, uranium and most other elements heavier than iron,” explained George Fuller, a theoretical astrophysicist and professor of physics who directs UC San Diego’s Center for Astrophysics and Space Sciences. “These elements most likely formed in an environment rich with neutrons.” Read More

| 12 May 2016 : $40 Million Observatory to Search for Signals from Early Universe
UCSD has received $40 million in gifts to create and lead an observatory in Chile that’s expected to greatly improve scientists’ ability to study how the universe evolved after its calamitous birth 13.8 billion years ago. “The generosity of this award is unprecedented in our field, and will enable a major leap in scientific capability,” said Brian Keating, Professor of Physics at UCSD's Center for Astrophysics and Space Sciences and the current project director. “We have this beautiful edifice of everything that’s happened in the universe and the laws of physics since about a second after the Big Bang. But we want to go back orders of magnitude—perhaps as many as 30 orders of magnitude farther back in time or higher in temperature. We’re trying to understand the nature of matter and energy and understand the first moments of the universe, potentially what brought it into existence.” Here is the Union-Tribune press release, and the story in Nature.

| 2 May 2016 : Astronomers Discover Three Potentially Habitable Earth-Sized Worlds Around A Dim Star 40 Light-years Away
An international team of astronomers, including UC San Diego’s Professor Adam Burgasser and graduate student Daniella Bardalez Gagliuffi, has reported in Nature the discovery of three Earth-sized planets orbiting near the “habitable zone” of an ultracool dwarf star named TRAPPIST-1, 40 light years in the direction of the constellation Aquarius. These are the first terrestrial planets to be discovered around such a tiny and dim star, and opens a new avenue in the search for life beyond Earth. The planets were found via the transit method, in which a planet passing between us and its host star blocks a small portion of the starlight, producing a subtle but periodic dimming pattern. Multiple transits for this star were detected with the TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, and their timings indicate the presence of three planets with orbit periods between 1.5 days and 73 days. These short orbits are likely to be in or around the habitable zone of the star, a zone in which liquid water could potentially exist on the planets’ surfaces. Evidence that this is the case will have to wait until the 2018 launch of the James Webb Space Telescope, which will have the capability of measuring the chemical composition of these planets’ atmospheres. Also the ESO press release can be found here, USA Today story here, The Atlantic story here, National Geographic story here, and a conversation piece here. For the UCSD press release: Read More

| 28 October 2015 : The B-Mode Story You Haven't Heard
It's a tough time to be a B-mode.
B-modes rocketed to fame in March 2014, when a team of scientists working on an experiment called BICEP2 announced the first direct evidence for primordial gravitational waves rippling out from the earliest moments of the universe: a distinctive imprint in the cosmic microwave background (the light left over from the Big Bang) called "B-mode polarization," or B-modes for short. Polarization describes the way that light-waves are oriented, and B-mode waves are twisted into a swirling pattern. The detection of these swirls was a stunning confirmation of the theory of cosmic inflation. Suddenly, B-modes were electromagnetic celebrities. PBS story: Read More

| 22 January 2014 : Galaxies on FIRE: Star feedback results in less|
Assistant Professor of Physics 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 of Physics 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.

| 20 November 2012 : Professor Alison Coil awarded extensive access to the Keck Telescope over the next 4 years to undertake a new survey of distant galaxies
Associate Professor of Physics 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

| 21 September 2012 : CASS Director and Distinguished Professor of Physics George Fuller wins prestigious Hans Bethe Prize
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. Congratulations, Professor Fuller! Read More

| 20 August 2012 : Professor of Physics George Fuller co-authors paper with UCSD Physics graduate student JJ Cherry on how a halo of neutrinos alters physics of exploding stars
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

| 8 February 2011 : Profs. Alison Coil and Mark Theimens honored for improving diversity in the physical sciences at UCSD
Alison Coil, Assistant Professor of Physics, and Mark Theimens, Professor of Chemistry & Biochemistry and Dean of the Division of Physical Sciences, were recognized for helping women navigate the transition from graduate student to independent scientist, a critical time when many women drop out of the field. She has gathered a group of graduate students and postdocs in physics who regularly meet to discuss career strategies. With a roster of visitors and among themselves, they have talked about how to apply for jobs and negotiate an offer, how to counter the often unacknowledged biases that can work against their advancement, and the variety of employment opportunities available to people with a doctorate in physics.They also meet each spring with visiting prospective students, aiding the department's successful efforts to attract more women to the program. This thriving group now serves as a model for similar efforts to form communities among graduate students in other departments and for undergraduates. Chancellor Fox will recognize Theimens and Coil with campus-wide 2010 Equal Opportunity/Affirmative Action and Diversity Awards at a ceremony to be held Tuesday, February 8. Read More

| 16 February 2010 : Dr. Alison Coil awarded Sloan Research Fellowship
The Sloan Research Fellowships have been awarded since 1955 and is by far the oldest program of the Alfred P. Sloan Foundation, although those who receive the grants are among the youngest researchers the Foundation assists. The Fellowship program has grown in size and cost over the years and now includes several disciplines not covered in the beginning; but its purpose - to stimulate fundamental research by early-career scientists and scholars of outstanding promise - remains the same. The Sloan Research Fellowships support the work of exceptional young researchers early in their academic careers, and often at pivotal stages in their work," says Paul L. Joskow, President of the Alfred P. Sloan Foundation. Dr. Coil's field of research lies at the interface between large-scale structure and galaxy evolution, and she will receive a grant of $50,000 over a two year period. Congratulations, Professor Coil!
