[21.02] HST Imaging of Ongoing Ram Pressure Stripping in the Virgo Spiral NGC 4522

J. Kenney (Yale U.), T. Tal (Ben-Gurion U.), A. Abramson (Yale U.)

We present Hubble Space Telescope ACS images of the Virgo cluster spiral galaxy NGC 4522, one of the nearest and clearest cases for ongoing ram pressure stripping of a galaxy's ISM by an interaction with the gas in the intracluster medium. The images show extraplanar star clusters which formed from stripped gas, large-scale dust lanes leaving the plane of the stellar disk, and small-scale head-tail dust features, which we propose are dense gas clouds being ablated by the ICM wind after the low density ISM has been stripped.
