Charged black holes embedded in matter with anisotropic pressure: Horizon Structure and Quasinormal Mode Spectra
D. N. Garzon, Jiayi Zhang, Elena Kopteva +1
In realistic settings, black holes are expected to be embedded in astrophysical environments. These environments, including possible dark matter distributions, can modify observabl…

The crust of dark-matter admixed neutron stars: bulk properties and torsional oscillations
Jiayi Zhang, Hector O. Silva
We study how dark matter (DM) impacts the crust and the spectrum of torsional crust oscillations of dark-matter-admixed neutron stars (DANSs). We construct two-fluid equilibrium so…
