Numerical analysis of quasi-periodic oscillations with spherical spacetimes
Kuantay Boshkayev, Orlando Luongo, Marco Muccino
We numerically test quasi-periodic oscillations using three theoretically-motivated models of spacetime adopting neutron star sources. Then, we compare our findings with a spherica…
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…
Constraints on the transition redshift from the calibrated Gamma-ray Burst - correlation
Marco Muccino, Orlando Luongo, Deepak Jain
We constrain the deceleration-acceleration epoch, namely the transition redshift , adopting model-independent techniques that utilize a calibrated -…
Intermediate redshift calibration of Gamma-ray Bursts and cosmic constraints in non-flat cosmology
Orlando Luongo, Marco Muccino
We propose how to calibrate long gamma-ray burst (GRB) correlations employing intermediate redshift data sets, instead of limiting to catalogs. To do so, we examine the…
Accretion disk luminosity for black holes surrounded by dark matter with tangential pressure
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +2
We study the motion of test particles in the gravitational field of a Schwarzschild black hole surrounded by a spherical dark matter cloud with non-zero tangential pressure and com…
