Query: HI imaging of galaxies in X-ray bright groups   Environment plays an important role in the evolution of the gas contents of
galaxies. Gas deficiency of cluster spirals and the role of the hot
intracluster medium (ICM) in stripping gas from these galaxies is a well
studied subject. Loose groups with diffuse X-ray emmision from the intragroup
medium (IGM) offer an intermediate environment between clusters and groups
without a hot IGM. These X-ray bright groups have smaller velocity dispersion
and lower temperature than clusters, but higher IGM density than loose groups
without diffuse X-ray emission. A single dish comparative study of loose groups
with and without diffuse X-ray emission from the IGM, showed that the galaxies
in X-ray bright groups have lost more gas on average than the galaxies in non
X-ray bright groups. In this paper we present GMRT HI observations of 13
galaxies from 4 X-ray bright groups: NGC5044, NGC720, NGC1550 and IC1459. The
aim of this work is to study the morphology of HI in these galaxies and to see
if the hot IGM has in any way affected their HI content or distribution. In
addition to disturbed HI morphology, we find that most galaxies have shrunken
HI disks compared to the field spirals. This indicates that IGM assisted
stripping processes like ram pressure may have stripped gas from the outer
edges of the galaxies.
