Intracluster Planetary Nebulae in Clusters and Groups


We present the results from multiple surveys for intracluster planetary nebulae (IPNe) in nearby galaxy clusters and groups. We find that in the case of clusters, our observations imply: 1) the amount of intracluster starlight is significant, up to 20% of the total starlight, 2) the Virgo Cluster is elongated along our line of sight, and 3) the intracluster… (More)
