IGCs in the Virgo Cluster

ABSTRACT Preliminary results of the ACS Virgo Cluster Survey WFPC2 parallel observations are presented. We searched for intergalactic
globular clusters in 100 WFPC2 fields within the Virgo Cluster. We find globular clusters preferentially near the most luminous
cluster galaxies (M87, M49, and M60). For M87, the number density of globular clusters out to 70 kpc is consistent with that
determined by ground based studies of the globular cluster systems. The intergalactic nature of the population of globular
clusters we are detecting is still a matter of controversy.
