Ram Pressure Stripping in Clusters and Groups
Ram pressure stripping is an important process in the evolution of both dwarf galaxies and large spirals. Large spirals are severely stripped in rich clusters and may be mildly stripped in groups. Dwarf galaxies can be severely stripped in both clusters and groups. A model is developed that describes the stripping of a satellite galaxy’s outer H i disk and hot galactic halo. The model can be ap...
متن کاملRam Pressure Stripping in Groups: Comparing Theory and Observations
Ram pressure stripping may be one of the dominant mechanisms driving the evolution of galaxies in groups and clusters. In this paper, models of ram pressure stripping are confronted with observations of galaxy colors and star formation rates using a group catalog drawn from the Sloan Digital Sky Survey and model predictions based on an analytical model of stripping presented in Hester (2006). A...
متن کاملRam pressure stripping in a viscous intracluster medium
In the recent literature there is circumstantial evidence that the viscosity of the intracluster medium may not be too far from the Spitzer value. In this letter, we present two-dimensional hydrodynamical simulations of ram pressure stripping of disc galaxies in a viscous intracluster medium (ICM). The values of viscosity explored range between 0.1 and 1.0 times the Spitzer value. We find that ...
متن کاملThe Impact of Icm Substructure on Ram Pressure Stripping
Cluster galaxies moving through the intracluster medium (ICM) are expected to lose some of their interstellar medium (ISM) through ram pressure stripping and related ISM-ICM interactions. Using high-resolution cosmological simulations of a large galaxy cluster including star formation, we show that the ram pressure a galaxy experiences at a fixed distance from the cluster center can vary by wel...
متن کاملRam pressure stripping of disc galaxies orbiting in clusters .
We present 3D hydrodynamical simulations of ram pressure stripping of a disc galaxy orbiting in a galaxy cluster. In this paper, we focus on the properties of the galaxies’ tails of stripped gas. The galactic wakes show a flaring width, where the flaring angle depends on the gas disc’s cross-section with respect to the galaxy’s direction of motion. The velocity in the wakes shows a significant ...
