Extending the Comisso-Asenjo Energy Extraction Mechanism to Pure Lovelock Gravity
Chen Zhou, Ikhtiyor Eshtursunov, Sanjar Shaymatov +1
In this paper, we extend the Comisso-Asenjo magnetic reconnection (MR) mechanism to rotating black holes (BHs) in pure Lovelock/Gauss-Bonnet (GB) gravity in dimension $2N+2\leq D\l…
Plasma impact on black hole shadow and gravitational weak lensing for Schwarzschild-like black hole
Weiqiang Yang, Mirzabek Alloqulov, Ahmadjon Abdujabbarov +3
This article delves into the observational properties of a Schwarzschild-like black hole (BH). Initially, the research provides a succinct examination of the spacetime geometry and…
Spherically-symmetrical vacuum solution in Freund-Nambu scalar-tensor gravity
Akbar Davlataliev, Bobur Turimov, Bobomurat Ahmedov +3
Scalar--tensor theories of gravity provide a natural extension of general relativity and may predict naked singularities as alternative compact objects. In this work, we investigat…
Effect of gravitational lensing around black hole in dark matter halo in the presence of plasma
Zhiyu Dou, Akbar Davlataliev, Mirzabek Alloqulov +4
This article is devoted to the investigation of the observational properties of the Schwarzschild black hole (BH) surrounded by a dark matter (DM) halo. Our study commences with a…
