Effect of induced frame dragging on energy extraction from axially symmetric magnetized Reissner-Nordström BH and observational benchmarks
Ikhtiyor Eshtursunov, Chen Zhou, Sanjar Shaymatov +2
In this paper, we probe the effect of induced frame dragging on the energy extraction process via magnetic reconnection in axially symmetric magnetized Reissner-Nordström black hol…
Operator-Level Quantum-Classical Correspondence in Relativistic Quantum Theory and Curved Spacetime
Pankaj Sheoran, Gopal Kashyap, Sanjay Siwach
In a recent work \cite{Shaikh:2026nsi}, it was shown that for a non-relativistic particle, the operator equations of motion can be cast in the same differential form as Newton's eq…
Constraining ModMax Black Holes with EHT and GRAVITY Observations: Optical Signatures and Accretion Disk Properties
Tursunali Xamidov, Mirjavoxir Mirkhaydarov, Sanjar Shaymatov +2
In this work, we study photon propagation and the radiative properties of a thin accretion disk around a ModMax black hole and examine the effects of the charge (i.e. $Q^2 = Q^…
Comisso-Asenjo Mechanism in Rotating Gauged Supergravity Black Holes: Extended Comparison With Kerr Black Hole
Abhinav Jaguri, Hemwati Nandan, Pankaj Sheoran +1
In this paper, we investigate energy extraction via the Comisso-Asenjo (CA) magnetic reconnection process near a coupled gauged supergravity Black Hole (BH…
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…
Non-Monotonic Enhancement of the Magnetic Penrose Process in Kerr-Bertotti-Robinson Spacetime and its Implication for Electron Acceleration
Mirjavoxir Mirkhaydarov, Tursunali Xamidov, Pankaj Sheoran +2
We studied the magnetic Penrose process (MPP) in the Kerr-Bertotti-Robinson (KBR) spacetime, an exact rotating electrovacuum solution describing a black hole (BH) immersed in an in…
