A more stringent constraint on the mass ratio of binary neutron star merger GW170817
He Gao, Zhoujian Cao, Shunke Ai +1
Recently, the LIGO-Virgo collaboration reported their first detection of gravitational wave (GW) signals from a low mass compact binary merger GW170817, which is most likely due to…
Gravitational wave source localization for eccentric binary coalesce with a ground-based detector network
Sizheng Ma, Zhoujian Cao, Chun-Yu Lin +2
Gravitational wave source localization problem is important in gravitational wave astronomy. Regarding ground-based detector, almost all of the previous investigations only conside…
Note on the gravitational and electromagnetic radiation for the Einstein-Maxwell equations with cosmological constant
Xiaokai He, Zhoujian Cao, Jiliang Jing
In the middle of last century, Bondi and his coworkers proposed an out going boundary condition for the Einstein equations. Based on such boundary condition the authors theoretical…
Long-Term Postmerger Simulations of Binary Neutron Star Coalescence: Formation of Toroidal Remnants and Gravitational Wave Afterglow
Xuefeng Zhang, Zhoujian Cao
It has been estimated that a significant proportion of binary neutron star merger events produce long-lived massive remnants supported by differential rotation and subject to rotat…
Excitation of high frequency voices from intermediate-mass-ratio inspirals with large eccentricity
Wen-Biao Han, Zhoujian Cao, Yi-Ming Hu
The coalescence of a stellar-mass compact object together with an intermediate-mass black hole, also known as intermediate-mass-ratio inspiral, is usually not expected to be a viab…
A waveform model for eccentric binary black hole based on effective-one-body-numerical-relativity (EOBNR) formalism
Zhoujian Cao, Wen-Biao Han
Binary black hole systems are among the most important sources for gravitational wave detection. And also they are good objects for theoretical research for general relativity. Gra…
Magnetic-distortion-induced ellipticity and gravitational wave radiation of neutron stars: millisecond magnetars in short GRBs, Galactic pulsars, and magnetars
He Gao, Zhoujian Cao, Bing Zhang
Neutron stars may sustain a non-axisymmetric deformation due to magnetic distortion and are potential sources of continuous gravitational waves (GWs) for ground-based interferometr…
An axion-like scalar field environment effect on binary black hole merger
Qing Yang, Li-Wei Ji, Bin Hu +2
Environment, such as the accretion disk, could modify the signal of the gravitational wave from the astrophysical black hole binaries. In this article, we model the matter field ar…
Mass-redshift Degeneracy for Gravitational-wave Sources in the Vicinity of a Supermassive Black Hole
Xian Chen, Shuo Li, Zhoujian Cao
Retrieving the mass of a gravitational-wave (GW) source is a fundamental but difficult problem because the mass is degenerate with redshift. In astronomy, three types of redshift e…
The Gravitational-Wave Physics
Rong-Gen Cai, Zhoujian Cao, Zong-Kuan Guo +2
The direct detection of gravitational wave by Laser Interferometer Gravitational-Wave Observatory indicates the coming of the era of gravitational-wave astronomy and gravitational-…
