Boson Stars in Bumblebee Gravity and Their Gravitational Waveforms from Extreme-Mass-Ratio Inspirals
Mao-Jiang Liu, Long-Xing Huang, Yong-Qiang Wang +1
We investigate the impact of Lorentz violation on the compactness of mini-boson stars and the resulting gravitational-wave signals from extreme-mass-ratio inspirals (EMRIs) within…
Observational constraints on inflationary models with non-minimally derivative coupling by ACT
Qing Gao, Yanjiang Qian, Yungui Gong +1
The most recent data release from the Atacama Cosmology Telescope (ACT) reveals a larger value of the scalar spectral tilt , ruling out a broad class of inflationary attractor…
Gravitational wave cosmology
Ligong Bian, Rong-Gen Cai, Yu-Qi Dong +18
Gravitational waves (GWs) originating from cosmological sources offer direct insights into the physics of the primordial Universe, the fundamental nature of gravity, and the cosmic…
Electrically charged black holes in gravity with a background Kalb-Ramond field
Zheng-Qiao Duan, Ju-Ying Zhao, Ke Yang
We derive the exact solutions for electrically charged black holes both in the absence and presence of a cosmological constant in the gravitational theory with Lorentz violation in…
Static and spherically symmetric black holes in gravity with a background Kalb-Ramond field
Ke Yang, Yue-Zhe Chen, Zheng-Qiao Duan +1
The Lorentz symmetry of gravity is spontaneously broken when the nonminimally coupled Kalb-Ramond field acquires a nonzero vacuum expectation value. In this work, we present exact…
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…
