GalaRP#
Ram pressure is a physical process that a galaxy experiences when it travels through a gaseous medium, such as the intergalactic medium or the intracluster medium. The gas is stripped from the galaxy, which can lead to the formation of a tail of gas and stars. This process is known as ram pressure stripping. This process leads to the creation of “RPS Galaxies”: some of the most visually striking objects in galaxy evolution.
GalaRP
leverages the Gala python package, combined with nonconservative orbit
integration,
to simulate the larger-scale effects of ram pressure absent hydrodynamical instabilities. Its primary purpose is to
be an efficient tool for finding optimal setup conditions for hydrodynamical wind-tunnel simulations of ram pressure
stripping.
The central purpose of GalaRP
is to simulate (to first order) the expected large-scale conditions of an RP
interaction from a hydrodynamical simulation.
Development is active on Github, and the Authors encourage
updates and suggestions to improve and enhance its functionality. Furthermore, some videos showing what GalaRP
can
do are available (and can be used in presentations with credit given) on
Youtube.
