Long-lived quasinormal modes and asymptotic tails of regular Schwarzschild-like black holes in the presence of a magnetic field
Akbar Davlataliev, Bakhtiyor Narzilloev, Ibrar Hussain +2
We analyze the evolution of perturbations of a (charged) massive scalar field near a regular Simpson-Visser black hole, allowing for a non-zero external magnetic field. We show tha…
Particle Dynamics and Quasi-Periodic Oscillations in the GUP-Modified Schwarzschild Spacetime: Constraint Using Micro-Quasars Data
Husanboy Hoshimov, Odil Yunusov, Farruh Atamurotov +2
In this work, we have worked out dynamical aspects for the particles moving around the GUP-corrected-Schwarzschild (S-GUP) black hole. We have calculated the innermost stable circu…
Constraints on Metric-Palatini Gravity from QPO Data
Elham Ghorani, Samik Mitra, Javlon Rayimbaev +4
In this work, we study metric-Palatini gravity extended by the antisymmetric part of the affine curvature. This gravity theory leads to general relativity plus a geometric Proca fi…
Influence of scalar field in massive particle motion in JNW spacetime
Bobur Turimov, Akbar Davlataliev, Ahmadjon Abdujabbarov +1
In this paper, we investigated the motion of massive particles in the presence of scalar and gravitational fields, particularly focusing on the Janis-Newman-Winicour (JNW) naked si…
Gravitational lensing of neutrinos in the Rezzolla-Zhidenko spacetime
Mirzabek Alloqulov, Hrishikesh Chakrabarty, Daniele Malafarina +2
We consider gravitational lensing of neutrinos in the Rezzolla-Zhidenko spacetime in the weak-field limit with plane-wave approximation. We apply the analysis to an hypothetical sy…
Observed jet power and radiative efficiency of black hole candidates in Kerr + PFDM model
Bakhtiyor Narzilloev, Ahmadjon Abdujabbarov, Bobomurat Ahmedov +1
In this research, we explore the electromagnetic energy emitted by astrophysical black holes within the Kerr+PFDM spacetime, a model encompassing rotating black holes surrounded by…
