Offset Hα Emission and Ram Pressure Stripping in Satellite Galaxies
Abstract
We present our efforts to observe evidence of the ram pressure stripping of cold gas in satellite galaxies as they move through the intracluster/group medium. We have been looking for a statistical offset of Hα emission (representing the gas) and the r-band light (representing the stars) of ~3,000 galaxies using integral field data from the SDSSIV MaNGA survey. Using Marvin, a Python package developed for interactively working with MaNGA data cubes, we have mapped out the galaxies and determined their Hα/r-band offsets. We will present results on the dependence of the Hα offset on the the properties of the satellite galaxies, their alignment to and distance from the cluster/group center and on the cluster/group mass.
