A physical model for state transitions in black hole X-ray binaries
Chris Nixon, Greg Salvesen
We present an accretion cycle which can explain state transitions and other observed phenomena in black hole X-ray binaries. This model is based on the process of disc tearing, whe…
Modeling quasar accretion disc temperature profiles
Patrick B. Hall, E. S. Noordeh, L. S. Chajet +2
Microlensing observations indicate that quasar accretion discs have half-light radii larger than expected from standard theoretical predictions based on quasar fluxes or black hole…
SMBH accretion & mergers: removing the symmetries
Andrew King, Chris Nixon
We review recent progress in studying accretion flows on to supermassive black holes (SMBH). Much of this removes earlier assumptions of symmetry and regularity, such as aligned an…
Tearing up the disc: misaligned accretion on to a binary
Chris Nixon, Andrew King, Daniel Price
In a recent paper we have shown that the evolution of a misaligned disc around a spinning black hole can result in tearing the disc into many distinct planes. Tearing discs with ra…
Do jets precess... or even move at all?
Chris Nixon, Andrew King
Observations of accreting black holes often provoke suggestions that their jets precess. The precession is usually supposed to result from a combination of the Lense-Thirring effec…
