Gravitational Gertsenshtein-Zeldovich mechanism for the Association between GW190425 and FRB 20190425A
Shao-Qin Wu, Jing-Rui Zhang, Rong-Gen Cai +2
The temporal and spatial coincidence between the gravitational wave (GW) event GW190425 and the fast radio burst (FRB) event FRB 20190425A raises the intriguing possibility of a ph…
Detectability of axion-like dark matter for different time-delay interferometry combinations in space-based gravitational wave detectors
Yong-Yong Liu, Jing-Rui Zhang, Ming-Hui Du +3
In the space-based gravitational wave detections, the axion-like dark matter would alter the polarization state of the laser link between spacecrafts due to the birefringence effec…
Probing Spin-2 Ultralight Dark Matter with Space-based Gravitational Wave Detectors in the mHz Regime
Jing-Rui Zhang, Ju Chen, Heng-Sen Jiao +2
Spin-2 ultralight dark matter (ULDM) is a viable dark matter candidate and it can be constrained using gravitational wave (GW) observations. In this paper, we investigate the detec…
Angular correlation and deformed Hellings-Downs curve from spin-2 ultralight dark matter
Rong-Gen Cai, Jing-Rui Zhang, Yun-Long Zhang
The pulsar timings are sensitive to both the nanohertz gravitational-wave background and the oscillation of ultralight dark matter. The Hellings-Downs angular correlation curve pro…
Slowly rotating charges from Weyl double copy for Kerr black hole with Chern-Simons correction
Yi-Ran Liu, Jing-Rui Zhang, Yun-Long Zhang
The Weyl double copy builds the relation between gauge theory and gravity theory, especially the correspondence between gauge solutions and gravity solutions. In this paper, we obt…
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…
