Observational constraints on black hole spin

CS Reynolds - Annual Review of Astronomy and Astrophysics, 2021 - annualreviews.org
The spin of a black hole is an important quantity to study, providing a window into the
processes by which a black hole was born and grew. Furthermore, spin can be a potent …

Foundations of black hole accretion disk theory

MA Abramowicz, PC Fragile - Living Reviews in Relativity, 2013 - Springer
This review covers the main aspects of black hole accretion disk theory. We begin with the
view that one of the main goals of the theory is to better understand the nature of black holes …

General relativistic magnetohydrodynamic simulations of magnetically choked accretion flows around black holes

JC McKinney, A Tchekhovskoy… - Monthly Notices of the …, 2012 - academic.oup.com
Black hole (BH) accretion flows and jets are qualitatively affected by the presence of ordered
magnetic fields. We study fully 3D global general relativistic magnetohydrodynamic (MHD) …

Hot accretion flows around black holes

F Yuan, R Narayan - Annual Review of Astronomy and …, 2014 - annualreviews.org
Black hole accretion flows can be divided into two broad classes: cold and hot. Whereas
cold accretion flows consist of cool optically thick gas and are found at relatively high mass …

Measuring black hole spin using X-ray reflection spectroscopy

CS Reynolds - The Physics of Accretion onto Black Holes, 2015 - Springer
I review the current status of X-ray reflection (aka broad iron line) based black hole spin
measurements. This is a powerful technique that allows us to measure robust black hole …

GRMHD simulations of magnetized advection-dominated accretion on a non-spinning black hole: role of outflows

R Narayan, A Sądowski, RF Penna… - Monthly Notices of the …, 2012 - academic.oup.com
We present results from two long-duration general relativistic magneto-hydrodynamic
(GRMHD) simulations of advection-dominated accretion around a non-spinning black hole …

Black hole spin via continuum fitting and the role of spin in powering transient jets

JE McClintock, R Narayan, JF Steiner - Space Science Reviews, 2014 - Springer
The spins of ten stellar black holes have been measured using the continuum-fitting method.
These black holes are located in two distinct classes of X-ray binary systems, one that is …

Three-dimensional general relativistic radiation magnetohydrodynamical simulation of super-Eddington accretion, using a new code harmrad with M1 closure

JC McKinney, A Tchekhovskoy… - Monthly Notices of …, 2014 - academic.oup.com
Black hole (BH) accretion flows and jets are dynamic hot relativistic magnetized plasma
flows whose radiative opacity can significantly affect flow structure and behaviour. We …

Numerical simulations of super-critical black hole accretion flows in general relativity

A Sądowski, R Narayan, JC McKinney… - Monthly Notices of …, 2014 - academic.oup.com
A new general relativistic radiation magnetohydrodynamical code koral is described, which
employs the M1 scheme to close the radiation moment equations. The code has been …

Global radiation magnetohydrodynamic simulations of sub-Eddington accretion disks around supermassive black holes

YF Jiang, O Blaes, JM Stone… - The Astrophysical …, 2019 - iopscience.iop.org
We conduct global three-dimensional radiation magnetohydrodynamic simulations of the
inner regions of accretion flows around a 5× 10 8 M⊙ black hole, with mass accretion rates …
