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…
