Ram 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 halo gas in disk galaxies: Implications on galactic star formation in different environments
We numerically investigate evolution of gaseous halos around disk galaxies in different environments ranging from small groups to rich clusters in order to understand galaxy evolution in these environments. Our simulations self-consistently incorporate effects of ram pressure of intergalactic medium (IGM) on disk and halo gas of galaxies and hydrodynamical interaction between disk and halo gas ...
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...
متن کاملRam pressure stripping and the formation of cold fronts
Chandra and XMM-Newton observations of many clusters reveal sharp discontinuities in the surface brightness, which, unlike shocks, have lower gas temperature on the X-ray brighter side of the discontinuity. For that reason these features are called “cold fronts”. It is believed that some cold fronts are formed when a subcluster merges with another cluster and the ram pressure of gas flowing out...
متن کاملThe effect of ram pressure on the star formation, mass distribution and morphology of galaxies
Aims. We investigate the dependence of star formation and the distribution of the components of galaxies on the strength of ram pressure. Several mock observations in X-ray, Hα and HI wavelength for different ram-pressure scenarios are
