Gravitational Wave Phase shifts of black hole mergers in AGN Disks
Hiromichi Tagawa, Connar Rowan, János Takátsy +4
Ground-based gravitational wave (GW) detectors have discovered about 200 compact object mergers. The astrophysical origins of these events are highly debated, and it is possible th…
Analytical solutions of bound timelike geodesic orbits in effective-one-body frame
Chen Zhang, Wen-Biao Han
We derive the approximate analytical solutions of the bound timelike geodesic orbits in the effective-one-body (EOB) frame with extreme-mass ratio limit. The analytical solutions a…
Secondary spins of extreme mass ratio inspirals: A probe to the formation channels
Qiuxin Cui, Wen-Biao Han, Zhen Pan
Extreme mass-ratio inspirals (EMRIs), consisting of a secondary (stellar mass) black hole (BH) orbiting around a supermassive BH, are one of the primary targets for future spacebor…
Inferring the cosmological constant in early Universe only by gravitational waves
Song Li, Wen-Biao Han
The expansion of the Universe is accelerating which can be interpreted as due to the cosmological constant . In this study, we investigate the behavior of gravitational waves in…
