A full relativistic thin disc -- the physics of the plunging region and the value of the stress at the ISCO
William J. Potter
The widely used Novikov-Thorne relativistic thin disc equations are only valid down to the radius of the innermost stable circular orbit (ISCO). This leads to an undetermined bound…
The Feasibility of Magnetic Reconnection Powered Blazar Flares from Synchrotron Self-Compton Emission
Paul J. Morris, William J. Potter, Garret Cotter
Order of magnitude variability has been observed in the blazar sub-class of Active Galactic Nuclei on minute timescales. These high-energy flares are often difficult to explain wit…
Modelling blazar flaring using a time-dependent fluid jet emission model - an explanation for orphan flares and radio lags
William J. Potter
Blazar jets are renowned for their rapid violent variability and multiwavelength flares, however, the physical processes responsible for these flares are not well understood. In th…
Demonstration of a magnetic Prandtl number disc instability from first principles
William J. Potter, Steven A. Balbus
Understanding what determines the strength of MHD turbulence in accretion discs is a question of fundamental theoretical and observational importance. In this work we investigate w…
Using radiative energy losses to constrain the magnetisation and magnetic reconnection rate at the base of black hole jets
William J. Potter
We calculate the severe radiative energy losses which occur at the base of black hole jets using a relativistic fluid jet model, including in-situ acceleration of non-thermal lepto…
Surprises in astrophysical gasdynamics
Steven A. Balbus, WIlliam J. Potter
Much of astrophysics consists of the study of ionised gas under the influence of gravitational and magnetic fields. Thus, it is not possible to understand the astrophysical univers…
