Gamma-Ray Bursts, Neutron Star Mergers and Muti-Messenger Astrophysics


Speaker:Prof. Peter Meszaros
Affiliation:Dept. of Astronomy & Astrophysics, Pennsylvania State University
Date:December 18, 2017 (Monday)
Time:4:00 p.m.
Venue:Room 522, 5/F, Chong Yuet Ming Physics Building, HKU

Abstract
 

Gamma-Ray Bursts are the most energetic explosions in the Universe, and are among the most promising for detecting multiple non-electromagnetic signals, including gravitational waves, cosmic rays and very high energy neutrinos. Recently, a sub-class of short gamma-ray bursts arising from neutron star mergers was, for the first time, observed both via gravitational waves, as well as electromagnetically, establishing multi-messenger astrophysics as a new approach to understand cosmic high energy objects. I will discuss some of the latest observational and theoretical developments in the GRB and multi-messenger field.  

Coffee and tea will be served 20 minutes prior to the seminar.

Anyone interested is welcome to attend.
