Tearing up the disc: how black holes accrete
Chris Nixon, Andrew King, Daniel Price +1
We show that in realistic cases of accretion in active galactic nuclei or stellar-mass X-ray binaries, the Lense-Thirring effect breaks the central regions of tilted accretion disc…
Stable counteralignment of a circumbinary disc
Chris Nixon
In general, when gas accretes on to a supermassive black hole binary it is likely to have no prior knowledge of the binary angular momentum. Therefore a circumbinary disc forms wit…
Rapid AGN accretion from counter-rotating discs
Chris Nixon, Andrew King, Daniel Price
Accretion in the nuclei of active galaxies may occur chaotically. This can produce accretion discs which are counter-rotating or strongly misaligned with respect to the spin of the…
Broken discs: warp propagation in accretion discs
Chris Nixon, Andrew King
We simulate the viscous evolution of an accretion disc around a spinning black hole. In general any such disc is misaligned, and warped by the Lense-Thirring effect. Unlike previou…
