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…
Rapid post-merger gravitational-wave signals from magnetic black hole superradiance: novel approach to detect magnetic monopole and ultralight boson
Zhong-Hao Luo, Fa Peng Huang, Pengming Zhang +1
We present an analytic framework showing that a spinning black hole with net magnetic charge exhibits a greatly enhanced superradiant instability against charged scalar fields comp…
Analytical solutions of bound timelike geodesic orbits in effective-one-body frame
Chen Zhang, Wen-Biao Han
We derive the approximate analytical solutions of the bound timelike geodesic orbits in the effective-one-body (EOB) frame with extreme-mass ratio limit. The analytical solutions a…
Laboratory formation of scaled astrophysical outflows
Shun-yi Yang, Guang-yue Hu, Chao Xiong +7
Astrophysical systems exhibit a rich diversity of outflow morphologies, yet their mechanisms and existence conditions remain among the most persistent puzzles in the field. Here we…
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…
