Identifying lensed gravitational waves with physics-informed posterior learning
Tian-Yang Sun, Xiao Guo, Jing-Fei Zhang +1
Gravitational lensing of gravitational waves can probe compact lenses, dark matter substructure, and cosmological distances, but identifying lensed events is difficult when unrelat…
The Environmental Effects on Inspiraling Binary Black Hole Systems in the Centers of the LMC and M31
Meng Xu, Zhijin Li, Xiao Guo +1
Binary black hole (BBH) systems residing in the centers of galaxies evolve within complex astrophysical environments. These environments, comprising dark matter (DM) halos and bary…
Multiband Gravitational Wave Detection Prospects for M31 UCXB-1 System in Low and Middle Frequency Band
Xiao Guo, Zhoujian Cao, Zhiwei Chen
The recent discovery of M31 UCXB-1, the first extragalactic ultracompact X-ray binary (UCXB) with an orbital period of s, presents a unique laboratory for st…
Detectability of dark matter density distribution via gravitational waves from binary black holes in the Galactic center
Zhijin Li, Xiao Guo, Zhoujian Cao +1
The fundamental nature of dark matter (DM) remains unknown, with significant uncertainties in its density profile. DM environments surrounding massive binary black holes (BBHs) mod…
Estimation of gravitational wave from solar emerging magnetic flux tube
Siqi Guan, Shangbin Yang, Xiao Guo
This study investigates the gravitational waves (GWs) generated by the emergence of magnetic flux tubes in the solar convection zone. We focus on the upward buoyancy of magnetic fl…
Enhanced Localization of Dark Lensed Gravitational Wave Events Enables Host Galaxy Identification and Precise Cosmological Inference
Zhiwei Chen, Qingjuan Yu, Youjun Lu +1
Lensed gravitational wave (GW) events are expected to be powerful new probes of cosmology, contingent on redshift measurement by electromagnetic observations. Host galaxy identific…
