Inner radius and energy conditions of dark matter halos surrounding Schwarzschild black holes
Zibo Shen, Anzhong Wang, Shaoyu Yin
We study a class of analytic models for a dark matter halo surrounding a Schwarzschild black hole sitting at the center of a galaxy, with a variable inner radius at…

Einstein Cluster as Central Spiky Distribution of Galactic Dark Matter
Kei-ichi Maeda, Vitor Cardoso, Anzhong Wang
Using the Einstein cluster models, we construct a fully relativistic, spherically symmetric, spiky structure of matter distribution near a supermassive black hole. We introduce and…

Analytical models of supermassive black holes in galaxies surrounded by dark matter halos
Zibo Shen, Anzhong Wang, Yungui Gong +1
In this Letter, we present five analytical models in closed forms, each representing a supermassive black hole (SMBH) located at the center of a galaxy surrounded by dark matter (D…
