We consider the shape of an accretion disc whose outer regions are misaligned with the spin axis of a central black hole and calculate the steady state form of the warped disc in the case where the viscosity and surface densities are power laws in the distance from the central black hole. We discuss the shape of the resulting disc in both the frame of the black hole and that of the outer disc. We note that some parts of the disc and also any companion star maybe shadowed from the central…

The shape of an accretion disc in a misaligned black hole binary
We model the overall shape of an accretion disc in a semidetached binary system in which mass is transferred on to a spinning black hole the spin axis of which is misaligned with the orbital rotation
Mass and spin co-evolution during the alignment of a black hole in a warped accretion disc
In this paper, we explore the gravitomagnetic interaction of a black hole (BH) with a misaligned accretion disc to study BH spin precession and alignment jointly with BH mass M BH and spin parameter
A Study of a Tilted Thin Inner Accretion Disk around a Spinning Black Hole
The inner part of a thin accretion disk around a Kerr black hole can serve as an important tool to study the physics of the strong gravity regime. A tilt in such a disk with respect to the black hole
Circumbinary discs around merging stellar-mass black holes
A circumbinary disc around a pair of merging stellar-mass black holes may be shocked and heated during the recoil of the merged hole, causing a near-simultaneous electromagnetic counterpart to the
Tidal warping and precession of Be star decretion discs
Rapidly rotating Be stars are observed as shell stars when the decretion disc is viewed edge on. Transitions between the two implies that the discs may be warped and precessing. Type II X-ray
Warped Circumbinary Disks in Active Galactic Nuclei
We study a warping instability of a geometrically thin, non-self-gravitating disk surrounding binary supermassive black holes on a circular orbit. Such a circumbinary disk is subject to not only
Reprocessed emission from warped accretion discs induced by the Bardeen–Petterson effect
The broad Balmer emission-line profiles resulting from the reprocessing of UV/X-ray radiation from a warped accretion disc induced by the Bardeen-Petterson effect are studied. We adopt a thin warped
Dual black holes in merger remnants – II. Spin evolution and gravitational recoil
Using high-resolution hydrodynamical simulations, we explore the spin evolution of massive dual black holes orbiting inside a circumnuclear disc, relic of a gas-rich galaxy merger. The black holes
The Bardeen–Petterson effect in accreting supermassive black hole binaries: a systematic approach
Disc-driven migration is a key evolutionary stage of supermassive black hole binaries hosted in gas-rich galaxies. Besides promoting the inspiral, viscous interactions tend to align the spins of
Warping and tearing of misaligned circumbinary disks around eccentric supermassive black hole binaries
We study the warping and tearing of a geometrically thin, non-self-gravitating disk surrounding binary supermassive black holes on an eccentric orbit. The circumbinary disk is significantly

The evolution of misaligned accretion discs and spinning black holes
In this paper, we consider the process of alignment of a spinning black hole and a surrounding misaligned accretion disc. We use a simplified set of equations, that describe the evolution of the
Warped discs and the directional stability of jets in active galactic nuclei
Warped accretion discs in active galactic nuclei (AGN) exert a torque on the black hole that tends to align the rotation axis with the angular momentum of the outer disc. We compute the magnitude of
Aligning spinning black holes and accretion discs
We consider the alignment torque between a spinning black hole and an accretion disc whose angular momenta are misaligned. This situation must hold initially in almost all gas accretion events on to
A simple approach to the evolution of twisted accretion discs
A simple set of equations is introduced which governs the time evolution of a twisted accretion disc. The time evolution is governed by two «viscosities», one governing shear within the plane of the
Accretion Discs in Astrophysics
If we put a particle in a circular orbit around a central gravitating body, it will stay in that orbit. If we then extract energy and angular momentum from the particle we may allow it to spiral

Neufeld & Maloney have proposed a model in which the warp in the subparsec-scale molecular disk in NGC 4258 allows direct illumination of the disk by a central X-ray source, heating the gas to
