Residual Test for the Third Gravitational-Wave Transient Catalog
Dicong Liang, Ning Dai, Yingjie Yang
The residual test is commonly used to check the agreement between the gravitational wave signal and the theoretical waveform template. The basic idea of the residual test is to sub…
Detecting new fundamental fields with Pulsar Timing Arrays
Chao Zhang, Ning Dai, Qing Gao +3
Strong evidence of the existence of the Stochastic Gravitational-Wave Background (SGWB) has been reported by the NANOGrav, PPTA, EPTA and CPTA collaborations. The Bayesian posterio…
Importance of including higher signal harmonics in the modeling of extreme mass-ratio inspirals
Chao Zhang, Ning Dai, Dicong Liang
Extreme mass-ratio inspirals (EMRIs) are the most potential sources detectable by the Laser Interferometer Space Antenna (LISA). To analyze the influence of higher harmonics on par…
Extreme mass ratio inspirals in galaxies with dark matter halos
Ning Dai, Yungui Gong, Yang Zhao +1
Using an analytic, static, and spherically symmetric metric for a Schwarzschild black hole immersed in a dark matter (DM) halo with the Hernquist-type profile, we derive analytic e…
Intermediate Mass-Ratio Inspirals with Dark Matter Minispikes
Ning Dai, Yungui Gong, Tong Jiang +1
The dark matter (DM) distributed around an intermediate massive black hole (IMBH) forms an overdensity region called DM minispike. We consider the binary system which consists of a…
Constraint on Brans-Dicke theory from intermediate/extreme mass ratio inspirals
Tong Jiang, Ning Dai, Yungui Gong +2
Intermediate/Extreme mass ratio inspiral (I/EMRI) system provides a good tool to test the nature of gravity in strong field. Based on the method of osculating orbits, we compute th…
