Using horizon shadows to distinguish a black hole and a white hole
Chengyu Bi, Zhoujian Cao
Within theoretical frameworks such as loop quantum gravity, black holes may evolve into white holes through a quantum bounce. This paper uses general relativistic ray-tracing techn…
Constraining Lorentz symmetry breaking in bumblebee gravity with extreme mass-ratio inspirals
Sheng Long, Zhong-wu Xia, Huajie Gong +3
Extreme mass-ratio inspirals (EMRIs), with their long-lived and highly relativistic orbital evolution, can probe strong-field spacetime geometry and provide an important means to t…
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…
Multiband gravitational wave observations of eccentric escaping binary black holes from globular clusters
Yuetong Zhao, Abbas Askar, Youjun Lu +7
Stellar-mass binary black holes (sBBHs) formed in globular clusters (GCs) are promising sources for multiband gravitational wave (GW) observations, particularly with low- and middl…
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…
The effect of the gravitational constant variation on the phase of gravitational waves
Jiachen An, Bing Sun, Zhoujian Cao
We have previously investigated the effect of the gravitational constant variation on the gravitational wave propagation. Pure theoretical analysis indicates that the leading order…
