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…
On the instability of the fundamental mode of the Regge-Wheeler effective potential
Shui-Fa Shen, Guan-Ru Li, Ramin G. Daghigh +5
It was recently pointed out that the fundamental mode of the Regge-Wheeler effective potential is unstable against an insignificant Gaussian metric perturbation, which, in turn, mi…
Reflectionless and echo modes in asymmetric Damour-Solodukhin wormholes
Wei-Liang Qian, Qiyuan Pan, Ramin G. Daghigh +2
It is understood that the echo waveforms in ultracompact objects can be regarded as composed mainly of the asymptotic high-overtone quasinormal modes, dubbed echo modes, which pred…
Regge poles, grey body factors, and absorption cross sections for black hole metrics with discontinuity
Guan-Ru Li, Wei-Liang Qian, Qiyuan Pan +3
It was recently proposed by Rosato {\it et al.} and Oshita {\it et al.} that black hole greybody factors, as stable observables at relatively high frequencies, are more relevant qu…
