Accretion Disk Luminosity and Topological Characteristics for a Schwarzschild Black Hole Surrounded by King Dark Matter Halo
Soroush Zare, Farokhnaz Hosseinifar, Luis Miguel Nieto +4
This study delves into the intricate properties of a Schwarzschild black hole enveloped by King dark matter in an isotropic configuration. The thermodynamic characteristics of this…
Constraints on Kalb-Ramond Gravity from EHT Observations of Rotating Black Holes in Traceless Conformal Electrodynamics
Yassine Sekhmani, Kuantay Boshkayev, Mustapha Azreg-Aïnou +3
We present a phenomenological study of rotating, charged black holes in Einstein gravity coupled to a traceless (conformal) matter sector formed by ModMax nonlinear electrodynamics…
Constraints on the Sen black hole mass and charge from quasi-periodic oscillations
Kuantay Boshkayev, Marco Muccino
We analyze quasi-periodic oscillation data from selected X-ray binary systems hosting black holes. To model the spacetime geometry, we resort the static Sen solution -- originally…
Effects of matter with anisotropic pressure on the Fan-Wang regular black hole shadows
Yergali Kurmanov, Orlando Luongo, Daulet Berkimbayev +4
We here investigate the consequences of an exotic fluid, exhibiting negative radial and tangential pressures, \emph{de facto} violating the Zel'dovich limit, on a regular solution…
Accretion Disk Luminosity and Topological Characteristics for a Schwarzschild Black Hole Surrounded by a Hernquist Dark Matter Halo
Luis M. Nieto, Farokhnaz Hosseinifar, Kuantay Boshkayev +2
In this work, we study some characteristics and gravitational signatures of the Schwarzschild black hole immersed in a Hernquist dark matter halo (SBH-HDM). We determine the black…
Numerical analysis of quasiperiodic oscillations in the Hartle-Thorne spacetime
K. Boshkayev, T. Konysbayev, Ye. Kurmanov +2
We numerically analyze quasiperiodic oscillations (QPOs) using a well-established spacetime model with neutron star sources. Within the framework of general relativity, we present…
