Global structure and dynamics of slowly rotating accretion flows

, 2022
We study the global solutions of slowly rotating accretion flows around the supermassive black hole in the nucleus of an elliptical galaxy. The velocity of accreted gas surrounding the black hole is initially subsonic and then falls onto the black hole ...

Bondi Flow from a Slowly Rotating Hot Atmosphere [PDF]

, 2011
A supermassive black hole in the nucleus of an elliptical galaxy at the centre of a cool-core group or cluster of galaxies is immersed in hot gas. Bondi accretion should occur at a rate determined by the properties of the gas at the Bondi radius and the ...

Bridging Scales: How Much Do Supermassive Black Holes Grow in the Suppressed Bondi Regime?

The Astrophysical Journal Letters
The coevolution of supermassive black holes (SMBHs) and their host galaxies remains one of the central open questions in cosmology, rooted in the coupling between accretion, feedback, and the multiscale physics that links the event horizon to the ...

Bondi Accretion and the Problem of the Missing Isolated Neutron Stars

, 2019
A large number of neutron stars (NSs), similar to10(9), populate the Galaxy, but only a tiny fraction of them is observable during the short radio pulsar lifetime.

Theory of wind accretion

EPJ Web of Conferences, 2014
A review of wind accretion in high-mass X-ray binaries is presented. We focus attention to different regimes of quasi-spherical accretion onto the neutron star: the supersonic (Bondi) accretion, which takes place when the captured matter cools down ...

A Deep Chandra View of A2597: Bubbles, Shocks, Cold Fueling, and a Plasma Depletion Layer

The Astrophysical Journal
To examine how active galactic nucleus (AGN) feedback shapes the intracluster medium (ICM) and fuels black hole accretion in the cool-core galaxy cluster A2597, we present deep (∼600 ks) Chandra X-ray observations complemented by archival GMRT radio and ...

Radiative efficiency, variability and Bondi accretion on to massive black holes: the transition from radio AGN to quasars in brightest cluster galaxies [PDF]

, 2013
We examine unresolved nuclear X-ray sources in 57 brightest cluster galaxies to study the relationship between nuclear X-ray emission and accretion on to supermassive black holes.
