Luminosity of accretion disks around rotating regular black holes

open access: yesEuropean Physical Journal C: Particles and Fields
We study thin accretion disks in the gravitational field of a class of rotating regular black holes. Our objective is to determine the key parameters governing these accretion disks: the radius of the innermost stable circular orbit $$(r_{\textrm{ISCO}})$

Quasinormal modes and universality of the Penrose limit of black hole photon rings

open access: yesJournal of High Energy Physics
We study the physics of photon rings in a wide range of axisymmetric black holes admitting a separable Hamilton-Jacobi equation for the geodesics. Utilizing the Killing-Yano tensor, we derive the Penrose limit of the black holes, which describes the ...
