Horizon-redshift transfer in black-hole direct-wave damping
Wen-Biao Han, Ye Jiang
Direct waves from black-hole mergers may probe horizon dynamics, but their observed envelopes need not decay at the Kerr surface-gravity rate. We compute the complex-frequency spin…
Measurability of Quadrupole Deviations from Kerr in Binary black hole Mergers
Song Li, Wen-Biao Han
We investigate the measurability of black hole quadrupole deviations from Kerr using five binary black hole mergers observed by the LIGO-Virgo-KAGRA Collaboration with the beyond-g…
Long-Lived Ringing of Near-Extremal Kerr Black Holes Resonantly Driven by Extreme-Mass-Ratio Inspirals
Wen-Biao Han
Near-extremal Kerr black holes support zero-damped modes (ZDMs), whose small time-domain damping rates make them long-lived probes of the near-horizon region. We show that bound ex…
A self-consistent EOB--Teukolsky framework for generic extreme mass-ratio inspirals
Xingyu Zhong, Wen-Biao Han, Ye Jiang +2
We present a full-relativistic waveform model for extreme mass-ratio inspirals (EMRIs) by self-consistently combining the effective one-body (EOB) formalism with the Teukolsky equa…
Probing Active Galactic Nuclei and Measuring the Hubble constant with Extreme-Mass-Ratio Inspirals
Jian-Dong Liu, Wen-Biao Han, Hiromichi Tagawa
Extreme-mass-ratio inspirals (EMRIs) carry valuable information about their surrounding astrophysical environments. Over the course of their long-term evolution, interactions betwe…
Waveforms and Fluxes of Generic Extreme-Mass-Ratio Inspirals with a Spinning Secondary
Qiuxin Cui, Wen-Biao Han
Extreme mass-ratio inspirals (EMRIs), comprising a stellar-mass compact object (CO) orbiting a supermassive black hole (BH), are key targets for future space-based gravitational-wa…
A New High-Performing Method for Solving the Homogeneous Teukolsky Equation
Ye Jiang, Wen-Biao Han
The numerical waveforms for the extreme mass-ratio inspirals (EMRIs) require a huge amount of homogeneous solutions of the Teukolsky equation in the frequency domain. The calculati…
Mapping inspiral-merger-ringdown waveforms of binary black holes from black hole perturbation waveforms by machine learning
Xing-Yu Zhong, Wen-Biao Han, Ling Sun
Identifying weak gravitational wave signals in noise and estimating the source properties require high-precision waveform templates. Numerical relativity (NR) simulations can provi…
Assessing the systematic errors of extreme-mass-ratio inspirals waveforms for testing general relativity
Ping Shen, Qiuxin Cui, Wen-Biao Han
Gravitational wave (GW) observations from extreme-mass-ratio inspirals (EMRIs) are powerful tools for testing general relativity (GR). However, systematic errors arising from wavef…
The imprint of cosmic expansion history on the propagation of gravitational waves
Ye Jiang, Wen-Biao Han
Gravitational waves (GWs) are regarded as standard sirens for Cosmology. GWs from compact binary coalescence (CBC) can directly determine the luminosity distance but usually can no…
Tests of gravitational wave propagation with LIGO-Virgo catalog
Xian-Liang Wang, Shu-Cheng Yang, Wen-Biao Han
In the framework of general relativity (GR), gravitational waves (GWs) travel at the speed of light across all frequencies. However, massive gravity and weak equivalence principle…
Indication for a compact object next to a LIGO-Virgo binary black hole merger
Shu-Cheng Yang, Wen-Biao Han, Hiromichi Tagawa +2
The astrophysical origin of binary black hole (BBH) mergers remains uncertain, although many events have been observed by the LIGO-Virgo-KAGRA network. Such mergers are potentially…
Resolving "dirty" effects around black holes by decoupling the Teukolsky equation
Ye Jiang, Wen-Biao Han
Detecting the environment around the supermassive black holes and tests of general relativity are important applications of extreme-mass-ratio inspirals (EMRIs). There is still a c…
Tests of no-hair theorem with binary black-hole coalescences
Song Li, Wen-Biao Han, Shu-Cheng Yang
Test of the no-hair theorem is the primary target with gravitational waves from binary black holes. In this Letter, we analyze gravitational-wave data from the LIGO-Virgo-KAGRA det…
