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…
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…
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…
A mathematical form of force-free magnetosphere equation around Kerr black holes and its application to Meissner effect
Xiaobo Gong, Yi Liao, Zhaoyi Xu
Based on the Lagrangian of the steady axisymmetric force-free magnetosphere (FFM) equation around Kerr black holes(KBHs), we find that the FFM equation can be rewritten in a new fo…
Assessing the Effects of the Uncertainty in Reheating Energy Scale on Primordial Spectrum and CMB
Bo Feng, Xiaobo Gong, Xiulian Wang
The details of reheating energy scale is largely uncertain today, independent of inflation models. This would induce uncertainty in predicting primordial spectrum. Such u…
