Gravitational wave observations: Current results & future expectations — •Harald Pfeiffer for the LIGO Scientific-Virgo-KAGRA collaboration — Max Planck Institute for Gravitational Physics, Am Mühlenberg 1, 14476 Potsdam

Gravitational Wave (GW) Astronomy has blossomed since the ground-breaking discovery in 2015 of a GW emitted by two merging black holes. The third observing run of the LIGO and Virgo observatories has increased the number of GW signals to nearly 100. Three types of compact object binaries have now been discovered: binary black holes, binary neutron stars and mixed systems with one neutron star and one black hole. This large set of GW signals enables ever more diverse conclusions about fundamental physics and astrophysics, with results including the equation of state at supernuclear densities, the mass-distribution of black holes, properties of gamma ray bursts, the nature of gravity and cosmology. This talk gives an overview of the observations and the wide variety of scientific results enabled by them. We close with an outlook to future observing runs and GW detectors.
