Probing the black holes in a dark matter halo of M87 using gravitational wave echoes
Dong Liu, Yi Yang, Zheng-Wen Long
Variations at the event horizon structure of a black hole will emit the signals of the gravitational wave echoes associated with the ringdown of the binary black hole merger. In th…
Black hole surrounded by the pseudo-isothermal dark matter halo
Yi Yang, Dong Liu, Ali Övgün +2
The abundance of dark matter in the actual universe motivates us to construct the black hole spacetime enveloped by dark matter. In this paper, we derive a new spherically symmetri…
Modeling the black holes surrounded by a dark matter halo in the galactic center of M87
Dong Liu, Yi Yang, Zhaoyi Xu +1
In this paper, the structure of a dark matter halo can be well described by the mass model of M87 and the Einasto profile for the cold dark matter model, i.e., $ρ_{\text{eina}} (r)…
Rotating black hole mimicker surrounded by the string cloud
Yi Yang, Dong Liu, Ali Övgün +2
Traversable wormholes and regular black holes usually represent completely different scenarios. But in the black bounce spacetime they can be described by a same line element, whic…
Page Curve of AdS-Vaidya Model for Evaporating Black Holes
Chia-Jui Chou, Hans B. Lao, Yi Yang
We study an evaporating black hole in the boundary conformal field theory (BCFT) model under the fully time-dependent AdS-Vaidya spacetime geometry. We introduce the time-dependent…
