  • The Erez-Rosen Solution Versus the Hartle-Thorne Solution 
    Boshkayev, Kuantay; Quevedo, Hernando; Nurbakyt, Gulmira; Malybayev, Algis; Urazalina, Ainur (MDPI, 2019-10)
    In this work, we investigate the correspondence between the Erez–Rosen and Hartle–Thorne solutions. We explicitly show how to establish the relationship and find the coordinate transformations between the two metrics. For ...
  • Extended logotropic fluids as unified dark energy models 
    Boshkayev, Kuantay; D'Agostino, Rocco; Luongo, Orlando (Springer, 2019-04)
    We study extended classes of logotropic fluids as unified dark energy models. Under the hypothesis of the Anton–Schmidt scenario, we consider a universe obeying a single fluid model with a logarithmic equation of state. ...
  • IMPRINT OF PRESSURE ON CHARACTERISTIC DARK MATTER PROFILES: THE CASE OF ESO0140040 
    Boshkayev, Kuantay; Konysbayev, Talgar; Kurmanov, Ergali; Luongo, Orlando; Muccino, Marco (MDPI, 2020-10-22)
    We investigate the dark matter distribution in the spiral galaxy ESO0140040, employing the most widely used density profiles: the pseudo-isothermal, exponential sphere, Burkert, Navarro-Frenk-White, Moore and Einasto ...
  • NEUTRINO OSCILLATION IN THE Q-METRIC 
    Boshkayev, Kuantay; Luongo, Orlando; Muccino, Marco (EDP Sciences, 2020-10-19)
    We investigate neutrino oscillation in the field of an axially symmetric space-time, employing the so-called q-metric, in the context of general relativity. Following the standard approach, we compute the phase shift ...
