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…
Geometric properties versus particle motion in the Fan-Wang spacetime
Gulnara Suliyeva, Kuantay Boshkayev, Talgar Konysbayev +7
In this work, we explore general relativistic effects and geometric properties of the Fan-Wang spacetime, one of the simplest regular solutions that can be obtained in nonlinear el…
Accretion disk luminosity around rotating naked singularities
Yergali Kurmanov, Kuantay Boshkayev, Talgar Konysbayev +6
We explore circular geodesics of neutral test particles in the gravitational field of a rotating deformed mass. The geometry around this source is described by the Quevedo-Mashhoon…
Accretion disks properties around regular black hole solutions obtained from non-linear electrodynamics
Yergali Kurmanov, Kuantay Boshkayev, Talgar Konysbayev +5
We investigate a family of spherically symmetric, static, charged regular black hole solutions derived within the framework of Einstein-nonlinear electrodynamics. Our study focuses…
Luminosity of accretion disks around rotating regular black holes
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +4
We consider thin accretion disks in the field of a class of rotating regular black holes. For this purpose, we obtain the radius of the innermost stable circular orbit, …
Accretion disk in the Hartle-Thorne spacetime
Yergali Kurmanov, Marco Muccino, Kuantay Boshkayev +4
We consider the circular motion of test particles in the gravitational field of a rotating deformed object described by the Hartle-Thorne metric. This metric represents an approxim…
Numerical analyses of M31 dark matter profiles
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +4
We reproduce the rotation curve of the Andromeda galaxy (M31) by taking into account its bulge, disk, and halo components, considering the last one to contain the major part of dar…
Luminosity of accretion disks in compact objects with quadrupole
Kuantay Boshkayev, Talgar Konysbayev, Ergali Kurmanov +3
We consider the circular motion of test particles in the gravitational field of a static and axially-symmetric compact object described by the -metric. To this end, we calculate…
