Keck Week Video #16: Cosmic Explosions: Gamma Ray Bursts and Other Transient Events from Keck – Dr. Shrinivas Kulkarni

Gamma ray bursts are the brightest electromagnetic events known in the Universe. They emit a narrow beam of intense radiation during a supernova when a massive star collapses into a neutron star or a black hole.

Dr. Shrinivas Kulkarni from the California Institute of Technology gives an illuminating presentation on how spectroscopy from Keck Observatory gives insight into the most powerful forces in the Universe.
