The Characteristic Star Formation Histories of Galaxies from z~2-7

Colloquium: Astronomy Colloquia | September 27 | 4 p.m. | 2 LeConte Hall

Speaker/Performer: Naveen Reddy, UC Riverside

Sponsor: Department of Astronomy

We use a large spectroscopic sample of L* galaxies at redshifts 1.5 < z < 3.4 with Keck, Hubble, and Spitzer observations, to study the average star formation history of galaxies at z~2. We first perform a detailed comparison between the bolometric SFRs of z~2 galaxies and those obtained from SED-fitting. This comparison suggests that exponentially-declining models are, in general, a poor...   More >

Planetary Protection... on Earth and Beyond

Seminar | September 27 | 5-6 p.m. | 421 Stanley Hall

Speaker/Performer: Margaret Race, Ph.D., SETI Institute

Sponsor: Science Technology Engineering Policy group

Margaret Race is concerned with protecting the planets. Actually, protecting all the planets: but especially Earth and Mars. Her work focuses on the scientific, technical, legal and societal issues of ensuring that missions to the Red Planet and other solar system bodies do not either inadvertently bring terrestrial microbes along, which would complicate our search for indigenous extraterrestrial...   More >
