The Possible Equation Of State Of Dark Matter in Low Surface Brightness Galaxies
Xiaobo Gong, Meirong Tang, Zhaoyi Xu
The observed rotation curves of low surface brightness (LSB) galaxies play an essential role in studying dark matter, and indicate that there exists a central constant density dark…
Constraining the Rastall parameters in static spacetimes with galaxy-scale strong gravitational lensing
Rui Li, Jiancheng Wang, Zhaoyi Xu +1
Recently, Rastall gravity is undergoing a significant surge in popularity. We obtain a power-law total mass-density profile for the inner region (within several effective radius) o…
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…
The discrepancy between Einstein mass and dynamical mass for SIS and power-law mass models
Rui Li, Jiancheng Wang, Yiping Shu +1
We investigate the discrepancy between the two-dimensional projected lensing mass and the dynam- ical mass for an ensemble of 97 strong gravitational lensing systems discovered by…
