英文摘要The gravitational waves (GWs) from the merger events of binary black hole (BH-BH) and binary neutron star (NS-NS) have been detected by LIGO-Virgo (O1 and O2). Besides, GWs from the NS-BH mergers have been recently reported and might be hopefully confirmed in the near future. The mass distributions of these merger events are poorly understood now; thus, LIGO-Virgo adopted a simple cut rule for chirp mass (M) to distinguish the GW event candidates: M < 2.1 M-circle dot for NS-NS, 2.1 M-circle dot < M < 4.35 M-circle dot for NS-BH, and M > 4.35 M-circle dot for BH-BH. We tested its validity by simulating the chirp mass (M) distributions in two synthetic models, i.e., Model Galaxy and Model LIGO, in which the masses of BHs and NSs are observed by the electromagnetic spectrum observations in our Galaxy and inferred by LIGO-Virgo detection (O1 and O2), respectively. The simulation shows that it is unsuitable for Model LIGO due to the BHs inferred by LIGO-Virgo are usually bigger than those in our Galaxy, and M of NS-BH events would distribute in the range of 2.1 M-circle dot < M < 7.3 M-circle dot, which partially overlaps with those of BH-BH events. Therefore, we suggest that the new searching round of LIGO-Virgo (e.g., O3) should carefully seek out the underlying NS-BH candidates in the range of 2.1 M-circle dot < M < 7.3 M-circle dot.
