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 the hot gaseous halos of galaxies in groups and clusters
We use a large suite of carefully controlled full hydrodynamic simulations to study the ram pressure stripping of the hot gaseous halos of galaxies as they fall into massive groups and clusters. The sensitivity of the results to the orbit, total galaxy mass, and galaxy structural properties is explored. For typical structural and orbital parameters, we find that ∼ 30% of the initial hot galacti...
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 ...
متن کاملRam pressure stripping of disk galaxies in galaxy clusters
While galaxies move through the intracluster medium of their host cluster, they experience a ram pressure which removes at least a significant part of their interstellar medium. This ram pressure stripping appears to be especially important for spiral galaxies: this scenario is a good candidate to explain the differences observed between cluster spirals in the nearby universe and their field co...
