Large-Scale Structure in the Direction of the Virgo Cluster
Abstract
We explore the distribution of galaxies behind the Virgo cluster out to z < 0.1, using the CfA redshift catalog, ZCAT, in conjunction with Abell clusters and pencil beam surveys as other tracers of large-scale structure. The field galaxies of ZCAT are found to trace the same overdensity as indicated by a supercluster defined by Abell clusters in the catalog of Einasto et al. [MNRAS, 269,351(1994)]. On even larger scales, galaxy peaks in three different pencil beam lines of sight toward the Virgo cluster are all found to fall at z ~ 0.08. We show this similarity in redshift to have a small probability of being caused by a random alignment, suggesting a sheet-like structure at that redshift, spanning >~ 150h_75_^-1^ Mpc.
