Description

In my invited talk, I will explain recent topics concerning three types of merger signals of gravitational waves related to primordial black holes: 1) dark matter primordial black holes, 2) nano-Hz gravitational waves produced by binary supermassive black holes seeded by primordial black holes, and 3) ultra-light binary primordial black holes with the memory burden effect.
