Disc tearing: implications for black hole accretion and AGN variability
Anagha Raj, Chris Nixon
Accretion discs around black holes power some of the most luminous objects in the Universe. Discs that are misaligned to the black hole spin can become warped over time by Lense-Th…
Be star discs: powered by a non-zero central torque
Chris Nixon, Jim Pringle
Be stars are rapidly rotating B stars with Balmer emission lines that indicate the presence of a Keplerian, rotationally supported, circumstellar gas disc. Current disc models, ref…
Nonthermal filaments from the tidal destruction of clouds in the Galactic center
Eric R. Coughlin, C. J. Nixon, Adam Ginsburg
Synchrotron-emitting, nonthermal filaments (NTFs) have been observed near the Galactic center for nearly four decades, yet their physical origin remains unclear. Here we investigat…
The persistence of pancakes and the revival of self-gravity in tidal disruption events
Eric R. Coughlin, C. J. Nixon, Patrick R. Miles
The destruction of a star by the tides of a supermassive black hole (SMBH) powers a bright accretion flare, and the theoretical modeling of such tidal disruption events (TDEs) can…
Accretion discs with non-zero central torque
C. J. Nixon, J. E. Pringle
We present analytical and numerical solutions for accretion discs subject to a non-zero central torque. We express this in terms of a single parameter, , which is the ratio of o…
Instability of non-Keplerian warped discs
Suzan Dogan, Chris Nixon
Many accretion discs are thought to be warped. Recent hydrodynamical simulations show that (i) discs can break into distinct planes when the amplitude of an imposed warp is suffici…
