Evidence for Supermassive Black Hole Binaries
Martin G. H. Krause, Martin A. Bourne, Silke Britzen +10
We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy…
Converged simulations of the nozzle shock in tidal disruption events
Fangyi Fitz Hu, Ilya Mandel, Rebecca Nealon +1
When debris from a star that experienced a tidal disruption events (TDE) after passing too close to a massive black hole returns to pericenter on the second passage, it is compress…
The Bardeen-Petterson effect in accreting supermassive black-hole binaries: disc breaking and critical obliquity
Rebecca Nealon, Enrico Ragusa, Davide Gerosa +2
The inspiral of supermassive black-hole binaries in gas-rich environment is driven by the presence of an accretion disc and viscous interactions tend to align the spin of the black…
Gravitational wave emission from unstable accretion discs in tidal disruption events
M. Toscani, G. Lodato, R. Nealon
Gravitational waves can be emitted by accretion discs if they undergo instabilities that generate a time varying mass quadrupole. In this work we investigate the gravitational sign…
Generalised warped disk equations
Rebecca G. Martin, Stephen H. Lubow, J. E. Pringle +6
The manner in which warps in accretion disks evolve depends on the magnitude of the viscosity. For small viscosity the warp evolves in a wave-like manner; for large visc…
On the Papaloizou-Pringle instability in tidal disruption events
Rebecca Nealon, Daniel J. Price, Clément Bonnerot +1
We demonstrate that the compact, thick disc formed in a tidal disruption event may be unstable to non-axisymmetric perturbations in the form of the Papaloizou-Pringle instability.…
Apsidal precession, disc breaking and viscosity in warped discs
Rebecca Nealon, Chris Nixon, Daniel J. Price +1
We demonstrate the importance of general relativistic apsidal precession in warped black hole accretion discs by comparing three - dimensional smoothed particle hydrodynamic simula…
On the Bardeen-Petterson Effect in black hole accretion discs
Rebecca Nealon, Daniel Price, Chris Nixon
We investigate the effect of black hole spin on warped or misaligned accretion discs - in particular i) whether or not the inner disc edge aligns with the black hole spin and ii) w…
