Rotating Black Hole Shadow in Perfect Fluid Dark Matter
Xian Hou, Zhaoyi Xu, Jiancheng Wang
We study analytically the shadow cast by the rotating black hole in the perfect fluid dark matter. The apparent shape of the shadow depends upon the black hole spin and the per…
Possibility of Identifying Matter around Rotating Black Hole with Black Hole Shadow
Zhaoyi Xu, Xian Hou, Jiancheng Wang
Shadows cast by the rotating black hole in perfect fluid matter are studied using analytical method. We consider three kinds of matter with standard equation of state in Cosmology:…
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…
Black Hole Space-time In Dark Matter Halo
Zhaoyi Xu, Xian Hou, Xiaobo Gong +1
For the first time, we obtain the analytical form of black hole space-time metric in dark matter halo for the stationary situation. Using the relation between the rotation velocity…
Black Hole Shadow of Sgr A in Dark Matter Halo
Xian Hou, Zhaoyi Xu, Ming Zhou +1
We study, for the first time, the shadow of the supermassive black hole Sgr A at the center of the Milky Way in dark matter halos. For the Cold Dark Matter and Scalar Field D…
Kerr-Newman-AdS Black Hole Surrounded by Perfect Fluid Matter in Rastall Gravity
Zhaoyi Xu, Xian Hou, Xiaobo Gong +1
The Rastall gravity is the modified Einstein general relativity, in which the energy-momentum conservation law is generalized to . In this work, we derive th…
Kerr-Anti-De-Sitter/De-Sitter Black Hole In Perfect Fluid Dark Matter Background
Zhaoyi Xu, Xian Hou, Jiancheng Wang
We obtain the Kerr-anti-de-sitter (Kerr-AdS) and Kerr-de-sitter (Kerr-dS) black hole (BH) solutions to the Einstein field equation in the perfect fluid dark matter background using…
Perfect fluid dark matter influence on thermodynamics and phase transition for a Reissner-Nordstrom-anti-de Sitter black hole
Zhaoyi Xu, Xian Hou, Jiancheng Wang +1
Based on Reissner-Nordstrom-anti-de Sitter(RN-AdS) black hole surrounded by perfect fluid dark matter, we study the thermodynamics and phase transition by extending the phase space…
