Constraining Lorentz symmetry breaking in bumblebee gravity with extreme mass-ratio inspirals
Sheng Long, Zhong-wu Xia, Huajie Gong +3
Extreme mass-ratio inspirals (EMRIs), with their long-lived and highly relativistic orbital evolution, can probe strong-field spacetime geometry and provide an important means to t…
Gravitational waveforms from periodic orbits around a novel regular black hole
Huajie Gong, Sheng Long, Xi-Jing Wang +3
We explore potential quantum gravity signatures by studying periodic orbits and their GW emissions around a novel regular black hole (BH) featuring a Minkowski core. Using a ration…
Bayesian inference for tidal heating with extreme mass ratio inspirals
Zhong-Wu Xia, Sheng Long, Qiyuan Pan +2
Extreme mass ratio inspirals (EMRIs) provide unique probes of near-horizon dissipation through the tidal heating. We present a full Bayesian analysis of tidal heating in equatorial…
Scalar perturbation around a rotating Kalb-Ramond BTZ black hole
Zhong-Wu Xia, Sheng Long, Huajie Gong +2
We investigate the scalar perturbation of a newly proposed Kalb-Ramond (KR) BTZ-like black hole. After the separation of variables for the Klein-Gordon equation, we find that the r…
