SHH method for SIDM: An SIDM-hydro hybrid method for simulating self-interacting dark matter
Sarah Schon, Michael Ryan, John Blakely +3
We present a new scheme to couple existing numerical methods for elastic self-interacting dark matter (SIDM) to the hydrodynamic equations via a continuous function of the local Kn…

Gas-dynamical Mass Measurements of the Supermassive Black Holes in the Early-Type Galaxies NGC 4786 and NGC 5193 from ALMA and HST Observations
Kyle M. Kabasares, Jonathan H. Cohn, Aaron J. Barth +10
We present molecular gas-dynamical mass measurements of the central black holes in the giant elliptical galaxies NGC 4786 and NGC 5193, based on CO(21) observations from the Ata…
