Four Black Holes Shadows
Yassine Sekhmani, Dhruba Jyoti Gogoi, Ratbay Myrzakulov +2
In this work, we examine the optical behaviors and thermodynamic phase structures using shadow analysis for four black holes. The study is conducte…
Observational constraints on the equation of state of viscous fluid in gravity
M. Koussour, A. Altaibayeva, S. Bekov +3
In this paper, we investigate a cosmological model based on viscous gravity as a potential alternative to dark energy. This model incorporates bulk viscosity and is analyz…
Signature flips in time-varying cosmological models with observational data
Yerlan Myrzakulov, M. Koussour, M. Karimov +1
In this study, we investigate signature flips within the framework of cosmological models featuring a time-varying vacuum energy term . Specifically, we consider the power-la…
Corrected Thermodynamics and Stability of Magnetic charged AdS Black Holes surrounded by Quintessence
Dhruba Jyoti Gogoi, Yassine Sekhmani, Shyamalee Bora +3
In this study, we explore the corrected thermodynamics of non-linear magnetic charged anti-de Sitter (AdS) black holes surrounded by quintessence, incorporating thermal fluctuation…
Orbits of particles with magnetic dipole moment around magnetized Schwarzschild black holes: Applications to S2 star orbit
Uktamjon Uktamov, Mohsen Fathi, Javlon Rayimbaev +1
This study provides a comprehensive analytical investigation of the bound and unbound motion of magnetized particles orbiting a Schwarzschild black hole immersed in an external asy…
Exploring late-time cosmic acceleration: A study of a linear cosmological model using observational data
A. Zhadyranova, M. Koussour, S. Bekkhozhayev +2
Understanding the evolution of dark energy poses a significant challenge in modern cosmology, as it is responsible for the universe's accelerated expansion. In this study, we focus…
Parameter Constraints on Traversable Wormholes within Beyond Horndeski Theories through Quasi-Periodic Oscillations
Farukh Abdulkhamidov, Petya Nedkova, Javlon Rayibaev +2
{\it Hunting} compact astrophysical objects such as black holes and wormholes, as well as testing gravity theories, are important issues in relativistic astrophysics. In this sense…
Phase structures and critical behaviour of rational non-linear electrodynamics AdS black holes in Rastall gravity
Yassine Sekhmani, Dhruba Jyoti Gogoi, Ratbay Myrzakulov +1
This research paper presents a black hole solution with a rational non-linear electrodynamics source in the Rastall gravity framework. The paper analyzes the thermodynamic properti…
