Physics from the Gravitational and Electromagnetic Waves of a Neutron Star Merger

Friday August 24, 2018
3:30 pm


 Presenter:  Dr. Daniel Kasen, UC Berkley and LBNL
 Series:  Physics and Astronomy Colloquium
 Abstract:  The recent detection of gravitational waves and associated electromagnetic emission from a binary neutron star merger has illuminated the physics of strong gravity and dense matter, and addressed long standing questions as to the origin of the heaviest elements in the universe. I will review our physical understanding of compact object mergers -- grounded in theoretical calculations and numerical simulations -- and will describe how observations of gravitational waves, high energy photons, and radioactively powered optical emission have important physical implications, including constraints on the speed of gravity, the equation of state of nuclear matter, and the nucleosynthesis of the heavy elements. I'll highlight the successes and limitations of models of neutron star mergers, and anticipate what we may see and learn in a hopeful future of numerous, diverse joint gravitational + electromagnetic wave detections
 Host:  Huaiyu (Mike) Duan
 Location:  Room 125, Dane Smith Hall
 

Refreshments will be available before the colloquium, at 03:15 pm, in in the lobby of Dane Smith Hall.
