Ringdown of a black hole sourced by a Burkert-density effective anisotropic source
Yi Yang, Gaetano Lambiase, Ali Ovgun +2
We construct a static, spherically symmetric black hole spacetime sourced by an effective anisotropic matter distribution whose energy density follows the cored Burkert profile. Th…

Black holes surrounded by dark matter spike: Spacetime metrics and gravitational wave ringdown waveforms
Dong Liu, Yi Yang, Zheng-wen Long
The supermassive black holes at the centers of galaxies may be surrounded by dark matter spike, which could leave detectable imprints on the gravitational wave signals they emit. I…
