LIGO-Virgo-KAGRA Discoveries Over Time

This animation shows the increasing sample of gravitational wave sources, starting before LIGO-Virgo-KAGRA went online (with only electromagnetic, EM, sources) and then moving through the three main data releases that are now available (GTWC-1, GWTC-2.1, and GWTC-3).  Watch as the sample of merging black holes and neutron stars has dramatically increased over the past few years, with the results of LIGO-Virgo-KAGRA.
