Alex Markowitz, Liz Rivers, and Rick Rothschild released the RXTE AGN Timing and Spectral Database (cass.ucsd.edu/~rxteagn -- click on "Read More" below to link to URL) containing light curves and spectral fits to over 100 active galaxies observed by the Rossi X-ray Timing Experiment over its 16 years of observations. Light curves in various X-ray bands and spectral data may be downloaded for immediate use. UCSD analysis of these objects may be found in Rivers et al. 2013 Astrophysical Journal, volume 772, page 114. Read More

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.

CASS Research Scientist Alexei Kritsuk, lead author on a paper published this month in MNRAS entitled "A Supersonic Turbulence Origin of Larson's Law," collaborated with other CASS research team members Michael Norman, Distinguished Professor of Physics and Director of SDSC, and undergraduate researcher Christoph Lee, to provide for the first time an explanation for the origin of three observed correlations between various properties of molecular clouds in the Milky Way galaxy known as Larson's Laws. The team utilized recent observational measurements and data analysis from six supercomputer simulations of the interstellar medium to conclude that there are not three independent Larson laws, but that all three correlations are due to the same underlying physics, i.e., the properties of supersonic turbulence.

Prof. Adam Burgasser will be presenting a collaborative work between faculty from Physics, Theatre Arts and Visual Arts at the upcoming La Jolla Playhouse Without Walls Festival, October 3-6, 2013. The piece, entitled "Our Star Will Die Alone", is a participatory, outdoor performance that tracks the lifecycle of a star from formation to white dwarf remnant, integrating stellar data and models with art and music design. Performances are Friday 10/4 and Saturday 10/5 at 10:30pm, and tickets are $15. A free preview will take place on Thursday at 8pm. All performances are on the south patio of Galbraith Hall.

UCSD-CASS Assistant Physics Professor Dusan Keres has been named a Hellman Faculty Fellow for 2013-2014. The award will support Keres' work in building a set of novel supercomputer numerical models of formation of galaxies that include important, but previously unappreciated, physics processes. Results from these models will greatly improve our understanding of the origin and evolution of galaxies such as our own Milky Way. Read More

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

CASS-Physics Graduate Student Daniella Bardalez Gagliuffi has been awarded a Friends of the International Center Graduate Scholarship for 2013-2014.
