Description
As satellite galaxies in clusters orbit through the ICM they experience a wind, which in many cases is strong enough to directly remove ISM material from the disc. This ram pressure stripping has a profound impact on the cold-gas content of cluster galaxies and can both compress gas in the disc, boosting star formation and stellar feedback, as well as directly strip cold-gas leading to rapid quenching. Understanding the results of this interplay between the hot cluster gas and the cold gas in galaxies requires deep, high-resolution observations of perturbed galaxies in nearby clusters. In this talk I will highlight a suite of recent results from the VERTICO ALMA survey on the impact of these environmental perturbations on molecular gas in the Virgo cluster. I will also preview the next phase of the VERTICO project, which will reach ~50pc spatial resolution in Virgo galaxies giving an unprecedented view into the properties of molecular gas in cluster galaxies at the scales of individual molecular clouds. I will finish with a discussion of the ultimate fate of the stripped ISM in these galaxies, particularly with respect to mixing into the ICM as well as contributions to the build-up of intracluster light.
