The detection rate of Inspiral and Quasi-normal modes of Pop III binary black holes which can confirm or refute the General Relativity in the strong gravity region

Using our population synthesis code, we found that the typical chirp mass of Pop III BH-BHs is \(\sim30~\msun\) with the total mass of \(\sim60~\msun\) so that the inspiral chirp signal as well as quasi normal mode (QNM) of the merging BH are interesting targets of KAGRA. The detection rate of the c...
