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…
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…
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…
