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^…

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…
