The HectoMAP cluster survey. II. X-ray clusters
Listed in IVOA Registry (Virtual Observatory)
We apply a friends-of-friends algorithm to the HectoMAP redshift survey and cross-identify associated X-ray emission in the ROSAT All-Sky Survey data (RASS).
Description
The resulting flux-limited catalog of X-ray cluster surveys is complete to a limiting flux of ~3x10^-13^erg/s/cm^2^ and includes 15 clusters (7 newly discovered) with redshifts z<=0.4. HectoMAP is a dense survey (~1200 galaxies deg^-2^) that provides ~50 members (median) in each X-ray cluster.
We provide redshifts for the 1036 cluster members. Subaru/Hyper Suprime-Cam imaging covers three of the X-ray systems and confirms that they are impressive clusters. The HectoMAP X-ray clusters have an LX-{sigma}cl scaling relation similar to that of known massive X-ray clusters.

The HectoMAP X-ray cluster sample predicts ~12000+/-3000 detectable X-ray clusters in RASS to the limiting flux, comparable with previous estimates.
