Energy in critical collapse
Yu Hu, Jun-Qi Guo, Junbin Li +2
We study the energy issue in critical collapse of a spherically symmetric scalar field. It is found that in critical collapse, the contribution from the material energy is greater…
Parameter estimation for Einstein-dilaton-Gauss-Bonnet gravity with ringdown signals
Cai-Ying Shao, Yu Hu, Cheng-Gang Shao
Future space-based gravitational-wave detectors will detect gravitational waves with high sensitivity in the millihertz frequency band, which provides more opportunities to test th…
New results on the dynamics of critical collapse
Jun-Qi Guo, Yu Hu, Pan-Pan Wang +1
We study the dynamics of the critical collapse of a spherically symmetric scalar field. Approximate analytic expressions for the metric functions and matter field in the large-radi…
Testing the polarization of gravitational wave background with LISA-TianQin network
Yu Hu, Pan-Pan Wang, Yu-Jie Tan +1
While general relativity predicts only two tensor modes for gravitational wave polarization, general metric theories of gravity allows up to four additional modes, including two ve…
Full analytic expression of overlap reduction function for gravitational wave background with pulsar timing arrays
Yu Hu, Pan-Pan Wang, Yu-Jie Tan +1
Pulsar timing array (PTA) is expected to detect gravitational wave background (GWB) in the nanohertz band within the next decade. This provides an opportunity to test the gravity t…
Dirac quasinormal modes of power-Maxwell charged black holes in Rastall gravity
Cai-Ying Shao, Yu Hu, Yu-Jie Tan Cheng-Gang Shao +2
In this paper, we study the quasinormal modes of the massless Dirac field for charged black holes in Rastall gravity. The spherically symmetric black hole solutions in question are…
