More Evidence for a Population of Intracluster Planetary Nebulae in the Virgo Cluster
We surveyed a 50 arcmin 2 region in the Virgo cluster core to search for intergalactic planetary nebulae and found 11 candidates in the surveyed area. The measured fluxes of these unresolved sources are consistent with these objects being planetary nebulae from an intergalactic population of stars, although we cannot exclude some minor
