Probing the vector charge of Sagittarius A* with pulsar timing
Zexin Hu, Lijing Shao, Rui Xu +2
Timing a pulsar orbiting around Sagittarius A* (Sgr A*) can provide us with a unique opportunity of testing gravity theories. We investigate the detectability of a vector charge ca…
Impact of overlapping signals on parameterized post-Newtonian coefficients in tests of gravity
Yixuan Dang, Ziming Wang, Dicong Liang +1
Gravitational waves have been instrumental in providing deep insights into the nature of gravity. Next-generation detectors, such as the Einstein Telescope, are predicted to have a…
Probing nontensorial gravitational waves with a next-generation ground-based detector network
Jierui Hu, Dicong Liang, Lijing Shao
In General Relativity, there are only two polarizations for gravitational waves. However, up to six polarizations are possible in a generic metric theory of gravity. Therefore, mea…
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…
Extended thermodynamics of the bumblebee black holes
Zhan-Feng Mai, Rui Xu, Dicong Liang +1
As a vector-tensor theory including nonminimal coupling between the Ricci tensor and a vector field, the bumblebee gravity is a potential theory to test Lorentz symmetry violation.…
Anatomy of parameter-estimation biases in overlapping gravitational-wave signals
Ziming Wang, Dicong Liang, Junjie Zhao +2
In future gravitational-wave (GW) detections, a large number of overlapping GW signals will appear in the data stream of detectors. When extracting information from one signal, the…
Improved bounds on the bosonic dark matter with pulsars in the Milky Way
Dicong Liang, Lijing Shao
Neutron stars (NSs) can be used to constrain dark matter (DM) since a NS can transform into a black hole (BH) if it captures sufficient DM particles and exceeds the Chandrasekhar l…
Bumblebee black holes in light of Event Horizon Telescope observations
Rui Xu, Dicong Liang, Lijing Shao
We report the existence of novel static spherical black-hole solutions in a vector-tensor gravitational theory called the bumblebee gravity model which extends the Einstein-Maxwell…
