Query: Tidal truncation of gas replenishment and global suppression of galactic
  star formation in distant clusters   Recent spectroscopic observations of galaxies in distant clusters have
revealed that the rate of star formation in star-forming galaxies is
significantly suppressed with respect to their counterparts in the field at a
similar redshift. It is, however, highly uncertain which physical processes are
responsible for this suppression. We present the results of a numerical
investigation of how the global tidal field of a cluster dynamically influences
the reservoir of halo gas surrounding a disk galaxy as it falls into the
cluster from the surrounding field. We find that the tidal field of the cluster
efficiently removes the halo gas from the galaxy, thereby halting its accretion
onto the disk, and thus the fueling of star formation within. This effectively
truncates the galaxy's star formation. We also find that this tidal truncation
does not depend very strongly on the orbit of the disk with respect to the
center of the cluster.
  These results suggest that the global tidal field of clusters is capable of
causing a widespread and uniform suppression of star formation in galaxies
accreted by the cluster. In light of these results, we discuss the importance
of this tidal truncation of the gas supply in the formation of S0 galaxies in
clusters.
