Indication for a compact object next to a LIGO-Virgo binary black hole merger
Shu-Cheng Yang, Wen-Biao Han, Hiromichi Tagawa +2
The astrophysical origin of binary black hole (BBH) mergers remains uncertain, although many events have been observed by the LIGO-Virgo-KAGRA network. Such mergers are potentially…

Distinguishing compact objects in extreme-mass-ratio inspirals by gravitational waves
Lu-Jia Xu, Shu-Cheng Yang, Wen-Biao Han +3
Extreme-mass-ratio inspirals (EMRIs) are promising gravitational-wave (GW) sources for space-based GW detectors. EMRI signals typically have long durations, ranging from several mo…

Tests of gravitational wave propagation with LIGO-Virgo catalog
Xian-Liang Wang, Shu-Cheng Yang, Wen-Biao Han
In the framework of general relativity (GR), gravitational waves (GWs) travel at the speed of light across all frequencies. However, massive gravity and weak equivalence principle…
