A More Rigorous Test Problem For Viscous Hydrodynamics Codes
Alexander J. Dittmann, Geoffrey Ryan
We advocate for a more stringent test problem for codes that aim to solve the equations of viscous hydrodynamics. Specifically, we discuss a nonuniform-density version of the commo…

Accretion onto supermassive black hole binaries
Eduardo M. Gutiérrez, Luciano Combi, Geoffrey Ryan
In this chapter, we give an overview of our current understanding of the physics of accreting massive black hole binaries (MBHBs), with a special focus on the latest developments i…
