Color Selection of Intracluster Globular Clusters in the Next Generation Virgo Survey
Abstract
The Next Generation Virgo Survey (NGVS) is a large, 104 square degree deep imaging survey (with CFHT's MegaCam) of the Virgo Cluster. One of the (many) science drivers for the NGVS is to quantify the population of intracluster globular clusters (IGCs) present between the galaxies. The large color baseline of the NGVS ugriz images allows for the effective extraction of candidates IGCs from background galaxies and foreground Milky Way stars. Here we present preliminary results on the definition of the selection of IGCs in color-color space, as well as early results on the surface density of IGCs over a large part the Virgo Cluster.
