Abstract:
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). The resulting flux-limited catalog of
X-ray cluster surveys is complete to a limiting flux of
∼3x10-13erg/s/cm2 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-σcl 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.
Description:
From 2009 to 2016, we conducted a redshift survey with the 300-fiber
spectrograph Hectospec mounted on the Multiple Mirror 6.5m telescope (MMT).
The 270 line mm-1 grating yields a wavelength range of 3700-9150Å
with a resolution of ∼6.2Å. To guarantee uniform sampling even in
the densest regions, we revisit each HectoMAP position ∼7 times.
For all the clusters found by the FoF algorithm in the HectoMAP
survey, we searched for X-ray emission in ROSAT all-sky survey (RASS;
Truemper 1993Sci...260.1769T 1993Sci...260.1769T).

The flux is obtained from the plateau of the growth curve analysis
method within the rest-frame energy band 0.5-2.0keV.
Note (2): The luminosity is corrected to give the values within an aperture
of R500.
