On the improved dynamics approach in loop quantum black holes
Hongchao Zhang, Wen-Cong Gan, Yungui Gong +1
In this paper, we consider the Böhmer-Vandersloot (BV) model of loop quantum black holes obtained from the improved dynamics approach. We adopt the Saini-Singh gauge, in which it w…
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…
Scalar induced gravitational waves in light of Pulsar Timing Array data
Zhu Yi, Qing Gao, Yungui Gong +2
The power-law parametrization for the energy density spectrum of gravitational wave (GW) background is a useful tool to study its physics and origin. While scalar induced secondary…
Detecting the secondary spin with extreme mass ratio inspirals in Scalar-Tensor theory
Hong Guo, Chao Zhang, Yunqi Liu +3
In this paper, we investigate the detectability of secondary spin in the extreme mass ratio inspirals system within a modified gravity model coupled with a scalar field. The centra…
Sky localization of space-based detectors with time-delay interferometry
Tong Jiang, Yungui Gong, Xuchen Lu
The accurate sky localization of gravitational wave (GW) sources is an important scientific goal for space-based GW detectors. The main differences between future space-based GW de…
Detecting vector charge with extreme mass ratio inspirals onto Kerr black holes
Chao Zhang, Hong Guo, Yungui Gong +1
Extreme mass ratio inspirals (EMRIs) are excellent sources for space-based observatories to explore the properties of black holes and test no-hair theorems. We consider EMRIs with…
