Pawan Kumar, a professor of astrophysics at the University of Texas, Austin, will be the featured speaker at a Department of Physics and Astronomy colloquium. His talk is titled, "Recent Advances in our Understanding of Gamma-Ray Bursts."
After a brief summary of key observational properties of gamma-ray bursts, Kumar will describe recent advances to our understanding of the emission mechanism. He will describe the strength and weaknesses of the various models. The high energy gamma-ray radiation detected by the Fermi satellite from GRBs and their origin also will be discussed. He will also summarize our understanding of the GRB central engine.
There will be refreshments starting at 3:30 p.m.
