Quasiperiodic oscillations as probes of rotating black holes in exponential dark matter environments
Madina Alimkulova, Kuantay Boshkayev, Sholpan Gumarova +2
We construct the rotating counterpart of a black hole embedded in a dark-matter halo with the exponential-sphere profile , using the Newman--Janis algorithm in the…
Constraints on Scalar--Tensor--Vector Gravity Theory Parameters Inferred from Quasiperiodic Oscillations
Marco Muccino, Kuantay Boshkayev, Binay Prakash Akhouri +2
We study circular geodesics of neutral test particles in the static charged solution of Scalar--Tensor--Vector Gravity (STVG), and we use the twin kilohertz quasiperiodic oscillati…
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…
Newtonian Shirokov Effect: Epicyclic Frequency Splitting from Mass Multipoles
Anuar Idrissov, Kuantay Boshkayev, Abylaikhan Tlemissov +1
We analyze small oscillations of nearly circular orbits in an axisymmetric Newtonian potential expanded in mass multipoles, as the classical counterpart of the relativistic Shiroko…
Shadow, Emission, and Strong-Field Lensing of Dilatonic Black Holes
Kuantay Boshkayev, Ainur Urazalina, Aidana Kurmanbek +2
We study the shadow and strong-field optical properties of a static, spherically symmetric dyon-like dilatonic black hole. The photon sphere radius, critical impact parameter, and…
