The stealth Kerr solution in the bumblebee gravity
Rui Xu, Zhan-Feng Mai, Dicong Liang
In this paper, we find Kerr solution accompanied with a nontrivial vector field as a solution to one of the simplest vector-tensor theories of gravity, namely the bumblebee model w…
Bumblebee cosmology: The FLRW solution and the CMB temperature anisotropy
Rui Xu, Dandan Xu, Lars Andersson +2
We put into test the idea of replacing dark energy by a vector field against the cosmic microwave background (CMB) observation using the simplest vector-tensor theory, where a mass…
Phase Transitions in the Early Universe: Impacts on BBN and CMB Observables
Rui Xu, Jiachen Lu, Shihao Deng +1
We explore the effects of low-scale cosmological first-order phase transitions on Big Bang Nucleosynthesis (BBN) and Cosmic Microwave Background (CMB) anisotropy and distortion. We…
The I-Love universal relation for polytropic stars under Newtonian gravity
Rui Xu, Alejandro Torres-Orjuela, Lars Andersson +1
The moment of inertia and tidal deformability of idealized stars with polytropic equations of state (EOSs) are numerically calculated under both Newtonian gravity and general relat…
Bumblebee cosmology: Tests using distance- and time-redshift probes
Xincheng Zhu, Rui Xu, Dandan Xu
In modern cosmology, the discovery of the universe's accelerated expansion has significantly transformed our understanding of cosmic evolution and expansion history. The unknown pr…
GWnext 2024: Meeting Summary
Alejandro Torres-Orjuela, Veronica Vazquez-Aceves, Rui Xu +19
GWnext 2024 was a meeting held in the Kavli Institute for Astronomy and Astrophysics at Peking University in March , 2024. In the meeting researchers at…
Combined search for Lorentz violation in short-range gravity
Cheng-Gang Shao, Yu-Jie Tan, Wen-Hai Tan +8
Short-range experiments testing the gravitational inverse-square law at the submillimeter scale offer uniquely sensitive probes of Lorentz invariance. A combined analysis of result…
