Query: Simulations of the Effects of Stripping and Accretion on Galaxy Haloes
  in Clusters   We present results from a series of hydrodynamic simulations investigating
ram pressure stripping of galactic haloes as the host galaxy falls radially
into a cluster. We perform a parameter study comprising of variations in
initial gas content, gas injection rate (via stellar mass loss processes),
galaxy mass and amplitude of infall. From the simulation results we track
variations in both physical quantities (e.g. gas mass) and directly observable
quantities (e.g. X-ray luminosities). The luminosity of the galaxy's X-ray halo
is found to compare favourably with the observationally determined correlation
with optical blue band luminosity (L_X:L_B) relation. Factors affecting the
X-ray luminosity are explored and it is found that the gas injection rate is a
dominant factor in determining the integrated luminosity. Observational
properties of the material stripped from the galaxy, which forms an X-ray wake,
are investigated and it is found that wakes are most visible around galaxies
with a substantial initial gas content, during their first passage though the
cluster. We define a statistical skewness measure which may be used to
determine the direction of motion of a galaxy using X-ray observations.
Structures formed in these simulations are similar to the cold fronts seen in
observation of cluster mergers where a sharp increase in surface brightness is
accompanied by a transition to a cooler region.
