Ringdown and greybody signatures of rational regular black holes in non-polynomial gravity
Shohzod Jumaniyozov, Javlon Rayimbaev, Azam Payzullaev +3
We study the quasinormal mode spectrum and wave-scattering properties of the four-dimensional rational regular black hole recently obtained in non-polynomial (quasi-topological) gr…
Pulsar magnetospheres in dynamical Chern-Simons gravity: deathline conditions and polar-cap particle acceleration
Sherzod Sayfiyev, Bobomurat Ahmedov, Chengxun Yuan +3
The role of surface gravity in neutron stars (NSs) is considerable in the radiation mechanisms of the surrounding plasma magnetosphere near the star surface, as they are highly mag…
Kerr-referenced analytical parametrization of rotating black holes in dynamical Chern-Simons gravity
Sardor Murodov, Bahodir Ahmedov, Bekzod Rahmatov +2
Rotating black holes in dynamical Chern-Simons gravity are known nonperturbatively mainly through numerical solutions, which limits their direct use in strong-field applications. W…
Massive neutral Dirac quasibound states in a Newman-Janis-generated rotating charged Kalb-Ramond black-hole geometry
Sardor Murodov, Olimjon Kholturayev, Bahodir Ahmedov +3
We study quasibound states of a massive neutral Dirac field in the Newman-Janis-generated rotating charged geometry used in Lorentz-violating Kalb-Ramond (KR) gravity. Rather than…
