Ram pressure stripping: An analytical approach
  We use an analytical approach to study ram pressure stripping with simple
models for discs and halo gas distribution to study the phenomena in cluster,
group and galaxy halos. We also study variations with galaxy properties and
redshift. In each case we model the worst case scenario (i.e., maximum effect
due to ram pressure). We show that there is little variation in the worst case
scenario with redshift. We find that gas discs in galaxies with a higher spin
parameter get stripped sooner than galaxies with a smaller spin parameter.
Galaxies in cluster halos get stripped of gas more effciently as compared to
group and galaxy halos: this is due to the higher infall speed and a higher
density of gas in the ICM due to a greater retention of baryons. We comment on
the limitations of our model and situations where a signiffcant amount of gas
may be retained in galaxy disc and also give an illustration for the same.
Lastly, we discuss implications for star formation in galaxies as these fall
into halos.
