Short-Hair Black Holes and the Strong Cosmic Censorship Conjecture
Zhiqin Tu, Meirong Tang, Zhaoyi Xu
The singularity problem has always been a focus of physicists' research. In order to solve this problem, Penrose proposed the cosmic censorship conjecture, but verifying this conje…
Deformed black hole immersed in dark matter spike
Zhaoyi Xu, Jiancheng Wang
If a lot of dark matter particles accumulate near the black hole, then the chances of detecting dark matter signals near a black hole are greatly increased. These effects may be ob…
The eccentricity enhancement effect of intermediate-mass-ratio-inspirals: dark matter and black hole mass
Meirong Tang, Jiancheng Wang
It was found that the dark matter (DM) in the intermediate-mass-ratio-inspiral (IMRI) system has a significant enhancement effect on the orbital eccentricity of the stellar massive…
Observational Constraints on the Rastall gravity from Rotation Curves of Low Surface Brightness Galaxies
Meirong Tang, Zhaoyi Xu, Jiancheng Wang
The Rastall gravity is a modification of Einstein's general relativity, in which the energy-momentum conservation is not satisfied and depends on the gradient of the Ricci curvatur…
A scenario on the power-law total mass-density profile of the inner regions of early-type-galaxies
Rui Li, Zhaoyi Xu, Jiancheng Wang +1
We naturally obtain a power-law total mass-density profile for the inner regions (within several effective radius) of early-type galaxies(ETGs) from space-time structures, which ar…
