Gravitational Waves: what we learned so far

Abstract: It took us almost a hundred years from Einstein’s publication to have observation-ready instruments. From the first detection GW150914, we are able to observe the universe in gravitational waves. Currently, after three observing runs of the LIGO-Virgo-KAGRA detector network, we were able to observe tens of mergers of binary black holes and a bunch of mergers involving at least one neutron star. The most interesting thing was what we can get from the data, like rates of compact objects mergers, constraints on neutron star equation of state, tests of GR in extreme regimes, but also estimation of Hubble constant directly from gravitational wave events observations.
