Abstract:
Intracluster stars - stars outside of individual galaxies - are a
sensitive measure of the poorly understood processes of galactic
mergers, cluster accretion, and tidal stripping that occur in galaxy
clusters. In particular, intracluster planetary nebulae are a useful
probe of intracluster light as a whole. We present a catalog of 318
intracluster planetary nebula candidates in the nearby Virgo Cluster
of galaxies, taken with the Kitt Peak National Observatory 4m
telescope. We detail the automated detection routines developed to
search for these candidates and discuss the routines' strengths and
weaknesses. We discuss the importance of contamination in the catalog,
and the likely causes. We present magnitudes and positions of these
candidates, suitable for spectroscopic follow-up observations.
Analyses of these candidates are presented in other papers of this
series.
