Supernova Light Curves Powered by Fallback Accretion
Jason Dexter, Daniel Kasen
Some fraction of the material ejected in a core collapse supernova explosion may remain bound to the compact remnant, and eventually turn around and fall back. We show that the lat…
Inhomogeneous accretion discs and the soft states of black hole X-ray binaries
Jason Dexter, Eliot Quataert
Observations of black hole binaries (BHBs) have established a rich phenomenology of X-ray states. The soft states range from the low variability, accretion disc dominated thermal s…
Tilted black hole accretion disc models of Sagittarius A*: time-variable millimetre to near-infrared emission
Jason Dexter, P. Chris Fragile
High-resolution, multi-wavelength, and time-domain observations of the Galactic centre black hole candidate, Sgr A*, allow for a direct test of contemporary accretion theory. To da…
Radiative Models of Sagittarius A* and M87 from Relativistic MHD Simulations
Jason Dexter, Eric Agol, P. Chris Fragile +1
Ongoing millimeter VLBI observations with the Event Horizon Telescope allow unprecedented study of the innermost portion of black hole accretion flows. Interpreting the observation…
