Journal ArticleDOI
Phantom: A smoothed particle hydrodynamics and magnetohydrodynamics code for astrophysics
Daniel J. Price,James Wurster,Terrence S. Tricco,Chris Nixon,Stéven Toupin,Alex R. Pettitt,Conrad Chan,Daniel Mentiplay,Guillaume Laibe,Simon C. O. Glover,Clare Dobbs,Rebecca Nealon,David Liptai,Hauke Worpel,Clément Bonnerot,Giovanni Dipierro,Giulia Ballabio,Enrico Ragusa,Christoph Federrath,Roberto Iaconi,Thomas Reichardt,Duncan Forgan,Mark Hutchison,T. Constantino,Ben A. Ayliffe,Kieran Hirsh,Giuseppe Lodato +26 more
TL;DR: Phantom as discussed by the authors is a fast, parallel, modular, and low-memory smoothed particle hydrodynamics code developed over the last decade for astrophysical applications in three dimensions.
Journal ArticleDOI
Tearing up the disc: misaligned accretion on to a binary
TL;DR: The calculations for this paper were performed on the Complexity node of the DiRAC2 HPC Facility which is jointly funded by STFC, the department of Business Innovation and Skills and the University of Leicester as mentioned in this paper.
Journal ArticleDOI
Retrograde accretion and merging supermassive black holes
TL;DR: In all cases the binary coalesces once it has absorbed the angular momentum of a gas mass comparable to that of the secondary black hole, and the coalescence time-scale is always ∼ M2/M.
Journal ArticleDOI
The Kozai-Lidov Mechanism in Hydrodynamical Disks
Rebecca G. Martin,Chris Nixon,Stephen H. Lubow,Philip J. Armitage,Daniel J. Price,S. Doğan,Andrew J. King +6 more
TL;DR: In this article, the authors used three-dimensional hydrodynamical simulations to show that a highly misaligned accretion disk around one component of a binary system can exhibit global Kozai-Lidov cycles, where the inclination and eccentricity of the disk are interchanged periodically.
Journal ArticleDOI
Tearing up the Disk: How Black Holes Accrete
TL;DR: In this paper, the Lense-Thirring effect was shown to break the central regions of tilted accretion disks around spinning black holes into a set of distinct planes with only tenuous flows connecting them.
