Gaseous Flux: How the Gas Flows of Dwarf Satellites are Influenced by Mass and Position
Abstract
Satellite dwarf galaxies of the Milky Way galaxy are significantly more likely to be quenched than surrounding field galaxies. We determine which gas removal processes contribute most to the quenching of satellites using 4 ultra-high-resolution simulations of analogue Milky Way galaxies created with the Charm N-Body GrAvity Solver (ChaNGa). We investigate the extent to which varying internal and external processes, such as supernovae (SNe), strangulation, tidal stirring, and RAM pressure stripping, influence the flow of gas in and out of satellites by examining the properties of the gas at the time of removal. We then examine their contribution to the quenching of dwarfs by exploring the relationship between star formation and gas flow.
