Accretion discsTheoryApplicationsAccretion disks are important for many astrophysics phenomena and objects such as: quasars,active galatic nuclei,X-ray binary systems,young stellar objects and gamma ray bursts etc. Here,we review the main contents of disk's theory and some recent progress associated...

Astrophysics in the lab By rotating the outer cylinder more slowly than the inner cylinder, and carefully controlling their respective motions, researchers can closely recreate the motions of evolving accretion discs as closely as possible. Their aim here is to determine whether turbulent flows could ...
We study the effect caused by external magnetic fields on the observed thermal spectra and iron line profiles of thin accretion discs formed around Kerr black holes and naked singularities. We aim to provide a tool that can be used to estimate the presence of magnetic fields in the ...

Abstract Accretion onto supermassive black holes (SBHs) is widely believed to be responsible for the phenomena of active galactic nuclei (AGN). While there has been considerable theoretical work on the inner regions of such accretion flows, little is known about the outer boundaries of AGN. Except...

Our results are applicable to thin Keplerian discs with an arbitrary radial distribution of density and a rather general prescription for the stardisc interaction. Temporal evolution is given in the form of quadrature which can be carried out numerically....
fluctuations became noticeably smaller, known as the “damping” time scale (usually several hundred days). They find that this damping time scale is related to SMBH mass over the entire range of SMBH masses observed in active galaxies and may even extend to smaller accretion di...
