ACCRETION DISK LUMINOSITY FOR BLACK HOLES SURROUNDED BY DARK MATTER WITH ANISOTROPIC PRESSURE

Kurmanov, E.; Boshkayev, K.; Giambò, R.; Konysbayev, T.; Luongo, O.; Malafarina, D.; Quevedo, H. (The Astrophysical Journal, 2022)

We investigate the luminosity of the accretion disk of a static black hole surrounded by dark matter with anisotropic pressure. We calculate all basic orbital parameters of test particles in the accretion disk, such as ...
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 ...
