The Physics department colloquia, when scheduled, begin at 3:30 PM on Friday afternoons, in Lapham Hall, Room 160 (in the Biology Bldg.). Coffee and cookies are available prior to the talks. The public is welcome to join. The title of …

Miniaturized Microwave & Millimeter Wave Biodetection for Molecular and Cellular Characterization

Dr. Katia Grenier, LAAS – CNRS (Toulouse, France)

Starbursts & Supernovae: Nature’s High Energy Particle Accelerator? Jay Gallagher, Department of Astronomy, UW-Madison The Milky Way is permeated by high-energy hadronic and leptonic cosmic rays that connect to interstellar magnetic fields and interact with interstellar gas. Although shocks in …

Hypervelocity Stars Dr. Warren R. Brown, Smithsonian Astrophysical Observatory Hypervelocity stars are ejected by the Galaxy's central massive black hole at speeds that exceed Galactic escape velocity. We discovered the first hypervelocity star in 2005, and have since found many …

The study of super-Eddington accretion is essential to our understanding of the growth of super-massive black holes in the early universe, the accretion of tidally disrupted stars, and the nature of ultraluminous X-ray sources.

Among the great surprises of modern cosmology was the discovery of Dark Energy. In this talk, I will introduce the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an ambitious project to study Dark Energy by tracing out 4 billion years of cosmic history, using a purpose-built radio telescope at the Dominion Radio Astrophysical Observatory

The development of X-ray free-electron lasers has enabled new experiments for studying uncrystallized biomolecules that were previously infeasible with traditional X-ray sources.

Quasar Absorption Lines: From Reionization to Dark Matter George Becker, Dept. of Physics & Astronomy, UC-Riverside Absorption patterns in the spectra of distant quasars are one of our most powerful probes of cosmic structure. The rich “forest” of lines produced …
