Repetitive Penrose Process in Kerr-Taub-NUT black hole spacetime
Mirzabek Alloqulov, Bobomurat Ahmedov, Chengxun Yuan
In this article, we study the repetitive Penrose process for the Kerr-Taub-NUT black hole (BH). First of all, we briefly review the spacetime of the Kerr-Taub-NUT BH, including hor…
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…
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…
Can a Dehnen-type dark matter halo affect the neutrino flavor oscillations?
Mirzabek Alloqulov, Ahmadjon Abdujabbarov, Bobomurat Ahmedov +1
The gravitational weak lensing of neutrinos in the presence of a Schwarzschild black hole surrounded by a Dehnen-type dark matter halo is investigated. The event horizon structure…
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…
Probing the gravity of a Schwarzschild black hole in the presence of a cloud of strings with EMRIs
Mirzabek Alloqulov, Ahmadjon Abdujabbarov, Bobomurat Ahmedov +1
Here, we explore the effect of the cloud of strings (CoS) on the gravitational waveforms of extreme mass ratio inspirals (EMRIs). The EMRI system consists of a supermassive black h…
