In a companion paper, we reported the self-consistent formation of quasar accretion disks
with inflow rates $\sim 10\,{\rm M_ {\odot}\, yr^{-1}} $ down to< 300 Schwarzschild radii from …

Accretion disc outbursts are re-occurring events observed in various astrophysical systems,
including X-ray binaries and cataclysmic variables. These outbursts are characterized by a …

Observational evidence and many numerical simulations show the existence of winds (ie,
uncollimated outflows) in the accretion systems of elliptical galaxy centers. One of the …

According to the standard thin disc theory, it is predicted that the radiation-pressure-
dominated inner region of a thin disc is thermally unstable, while observations suggest that it …

Accretion processes near black hole candidates are associated with the high-energy
emission of radiation from relativistic particles and outflows. It is widely believed that the …

Observational evidence and many numerical simulations show the existence of wind (ie,
uncollimated outflow) in accretion systems of the elliptical galaxy center. One of the primary …

In this paper, we explore the self-similarity time evolution of a hot accretion flow around a
compact object in the presence of a toroidal magnetic field. We focus on a simplified model …

Supermassive black hole binaries (SMBHBs) are, by all means, expected to exist; galaxies
contain supermassive black holes, galaxies merge, and, so, there ought to be galaxies …

We study the stability of a model of magnetized accretion disk, in whichoutflows play a
significant role in driving the inflow, and magnetic field is generated bya dynamo operating …

Changing-look active galaxies belong to very interesting objects because they are suddenly
changing the presence of broad emission lines in the optical domain, or their X-ray flux is …
