Probing Dark Matter with Gravitational Waves: Spin-Modulated Dephasing from Black Holes in Halos
Guoyang Fu, Yunqi Liu, Jian-Pin Wu +2
We develop a novel analytical framework for constructing axisymmetric black hole spacetimes sourced by dark matter (DM) halos. Applying this to extreme mass ratio inspirals (EMRIs)…
A metric solution for rotating black holes embedded in dark matter halos with central spikes
Rui-Hong Yue, Yu-Qian Zhao, Wei-Liang Qian
We propose an analytic metric describing rotating black holes surrounded by generic dark matter halos. This metric is an exact solution of the field equations that incorporates a d…
Effectiveness of nonflow suppression using multi-particle correlators
Chong Ye, Wei-Liang Qian, Yue Cui +4
As flow estimators, multi-particle correlators, particularly the higher-order ones, are generally regarded as effective tools for suppressing non-flow contributions. In this work,…
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…
Nonflow suppression in flow analysis with a maximum likelihood estimator
Chong Ye, Wei-Liang Qian, Cesar A. Bernardes +4
We show that the maximum likelihood estimator (MLE) is an effective tool for mitigating non-flow effects in flow analysis. To this end, one constructs two toy models that simulate…
Continued fraction method for high overtone quasinormal modes in effective potentials with discontinuity
Guan-Ru Li, Jodin C. Morey, Wei-Liang Qian +4
In this study, we extend Leaver's continued fraction method to evaluate black hole quasinormal modes (QNMs) in systems where the effective potential exhibits a discontinuity. Besid…
