  • The recent detection of gravitational waves (GWs) by LIGO-Virgo [1] has opened a new window on the universe. Binary systems of compact objects such as black holes and neutron stars emit tiny ripples in spacetime when they inspiral and merge together. The ground-based interferometric system LIGO-Virgo has been measuring several such events and a new generation of experiments, both ground-based and spaceborne, will be taking life in the next two decades, among which KAGRA [2] has just begun… CONTINUE READING
