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…
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…
Accretion disk luminosity for black holes surrounded by dark matter with anisotropic pressure
Kuantay Boshkayev, Roberto Giambò, Talgar Konysbayev +4
We investigate the luminosity of the accretion disk for a static black hole surrounded by dark matter with anisotropic pressure. We calculate all basic orbital parameters of test p…
Effects of non-vanishing dark matter pressure in the Milky Way galaxy
Kuantay Boshkayev, Talgar Konysbayev, Ergali Kurmanov +4
We consider the possibility that the Milky Way's dark matter halo possesses a non vanishing equation of state. Consequently, we evaluate the contribution due to the speed of sound,…

We check the dynamical and observational features of four typologies of logotropic dark energy models, leading to a \emph{thermodynamic cosmic speed up} fueled by a single fluid th…
