Horizon-Brightened Acceleration Radiation and the Deflection Angle Near a Degenerate Photon Sphere of Schwarzschild-like Quantum-Corrected Black Hole
Yunqiao Xu, Uktamjon Uktamov, Bobomurat Ahmedov +1
We investigate horizon-brightened acceleration radiation (HBAR) and a strong-deflection expansion for the deflection angle of light rays scattered in the vicinity of a degenerate p…
Spinning particle dynamics, epicyclic frequencies, and transient QPO signatures in Schwarzschild spacetime
Uktamjon Uktamov, Ali Ãvgün, Reggie C. Pantig +1
The paper analyzes how the spin of a test particle affects its motion, orbital stability, and epicyclic frequencies around a non‑rotating (Schwarzschild) black hole, and explores i…
Chaotic motion and power spectral density in Schwarzschild Bertotti-Robinson black hole spacetime
Yunqiao Xu, Uktamjon Uktamov, Pierros Ntelis +3
In this paper, we show that in weak field limit Schwarzschild Bertotti-Robinson black hole (Schwarzschild-BR BH) turns into Schwarzschild black hole immersed in external uniform ma…
New analytical model of static black hole with a dark matter halo and parametric constraints through quasiperiodic oscillations
Uktamjon Uktamov, Sanjar Shaymatov, Bobomurat Ahmedov +1
A novel analytical Schwarzschild-like black hole (BH) solution is derived. It exhibits a static BH with a dark matter (DM) halo characterized by a Dehnen-type density profile. This…
Horizon-Brightened Acceleration Radiation and Optical Signatures of Generic Regular Black Holes from Nonlinear Electrodynamics
Uktamjon Uktamov, Ali Ãvgün, Reggie C. Pantig +1
We investigate horizon-brightened acceleration radiation (HBAR) and optical signatures for a broad class of regular black holes sourced by nonlinear electrodynamics. The spacetimes…
New analytical model of rotating black hole with dark matter halo: constraints from EHT observations and accretion disk
Uktamjon Uktamov, Sanjar Shaymatov, Bobomurat Ahmedov +1
In this paper, we start from a static black hole (BH) immersed in a Deanne-type dark matter (DM) halo and employ the Newman-Janis algorithm (NJA) to generate the rotating black hol…
