Rethinking Ram Pressure Stripping of Elliptical Galaxies in Galaxy Clusters
Min-Su Shin (Univ. Michigan)

I present new results of ram pressure stripping simulations for elliptical galaxies in dense environments by using grid-based codes. First, I show ram pressure stripping effects with turbulent ISM in elliptical galaxies. I find that stripping is strongly suppressed by turbulent motion and the absence of instability on the boundary between ISM and ICM. Second, ram pressure stripping with turbulent magnetic fields is also investigated to understand how morphology of stripping changes and how strongly stripping efficiency decreases by magnetic fields. I discuss key differences between conventional ram pressure stripping simulations without turbulent gas and magnetic fields and our new simulations.
