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 parameterizat…
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…
The exponential metric: traversable wormhole and possible identification of scalar background
Eduard Mychelkin, Gulnara Suliyeva, Maxim Makukov
The static antiscalar solution of the Einstein-Klein-Gordon equations in the form of the Papapetrou exponential metric had been interpreted as a traversable wormhole with a throat…
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 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…
On the weak and strong field effects in antiscalar background
Eduard Mychelkin, Maxim Makukov, Gulnara Suliyeva +1
The triumph of general relativity under the banner "gravity is geometry" began with confirming the crucial effects within the Solar system and proceeded recently to the strong-fiel…
