Astronomy Seminar: Gravitational wave observations of merging black holes and neutron stars - inferring object and population properties

There is now an unprecedented population of eleven observations of gravitational waves detected by the LIGO and Virgo observatories during their first and second observing runs. I will present recent results detailing these individual gravitational sources, what they can tell us about the nature of General Relativity as well as how they give us a first glimpse of a hidden population of black holes. I will also highlight the observation of the merger of two neutron stars, and how the latest gravitational wave analysis is capable of shedding further light on this golden event.
