Testing dark matter density profiles based on Padé approximants of different orders

Talgar Konysbayev, Orlando Luongo, Marco Muccino +5

We investigate whether low-order Padé rational functions can be used as empirical density profiles for modeling dark matter halos from galaxy RCs. We introduce three parameterizati…

Schwarzschild-like Black Holes Submerged in an Exponential Density Dark Matter Profile

Kuantay Boshkayev, Yassine Sekhmani, Soroush Zare +3

We study a class of Schwarzschild black holes embedded in an exponential-spheroidal dark matter halo, modelled by a phenomenological density profile . By solvi…

Testing Scalar Field Dark Matter models in M31 galaxy through the Rotation Curve analysis

Gulnara Suliyeva, Kuantay Boshkayev, Talgar Konysbayev +2

We explore the viability of scalar field dark matter halo models through the rotation curve analysis of the Andromeda galaxy (M31), taking into account a realistic description of i…

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…

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…

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…
