报告摘要：There are now over 90 confident detections of compact binary coalescences from the first 3 observing runs by Advanced LIGO and Virgo. This includes the gravitational wave signal from a binary neutron star merger (GW170817) which was observed in conjunction with a very weak short gamma-ray bursts (GRB 170817A) as well as subsequent emissions across the electromagnetic spectrum. These multi-messenger observations provide a revealing glimpse into the complex astrophysics behind short gamma-ray bursts.

This presentation will present an overview of multi-messenger activities at the University of Glasgow, including a joint analysis of gamma-ray burst and binary neutron star event rates and the potential implications on cosmology and astrophysics.
