Magnetic Modification of Black Hole Photospheres with Image Contraction, Efficiency Shifts and Redshift Boosts in Schwarzschild-Bertotti-Robinson Spacetime
Javokhir Sharipov, Pankaj Sheoran, Sanjar Shaymatov
We investigate the optical and radiative signatures of an accretion disk around a Schwarzschild black hole (BH) immersed in a uniform magnetic field. The spacetime geometry is desc…
Optical Signatures of a Schwarzschild Black Hole in a Dehnen-Type Dark Matter Halo
Javokhir Sharipov, Jonibek Khasanov, Pankaj Sheoran +2
In this paper, the optical effects that occur near a Schwarzschild-like black hole (BH) with a Dehnen-type dark matter (DM) halo are explored. We first derive the photon…
Nonlinear electrodynamic black holes and their role in testing modified theories of gravity
Javokhir Sharipov, Mirzabek Alloqulov, Pankaj Sheoran +1
The nature of black holes (BHs) and their potential deviations from classical General Relativity (GR) remain central questions in modern astrophysics. Nonlinear electrodynamics (NE…
Periodic orbits and observational accretion disk around a Schwarzschild-like black hole surrounded by dark matter halo
Javokhir Sharipov, Tursunali Xamidov, Qiang Wu +2
In this work, we investigate the dynamics of periodic orbits and the properties of accretion disks around a Schwarzschild-like black hole (BH) immersed in a King-type dark matter (…
Observable thin accretion disk around a self-dual black hole in loop quantum gravity
Tursunali Xamidov, Javokhir Sharipov, Sanjar Shaymatov
In this paper, we study a self-dual black hole (BH) in Loop Quantum Gravity (LQG), analyzing both timelike and null geodesics. Using observational data from Mercury's perihelion sh…
