cds-question@unistra.frgalaxy-clustersvisible-astronomyspectroscopyredshiftedgalaxy-kinematicssurveysWe use dense redshift surveys to explore the properties of galaxy clusters selected from the redMaPPer catalog. Our new survey, Hectospec Cluster Survey of red-sequence-selected clusters (HeCS-red), includes 10589 new or remeasured redshifts from MMT/Hectospec observations of 27 redMaPPer clusters at redshifts z=0.08-0.25 with large estimated richnesses (richness estimate {lambda}>64). Our spectra confirm that each candidate cluster corresponds to a large overdensity in redshift space. The redMaPPer photometric redshifts have a slight bias toward higher redshifts. We measure the relation between velocity dispersion {sigma}p and {lambda}. The relation shows intrinsic scatter of 24% (and a range of 2x) in velocity dispersion at fixed richness. We extend our analysis to HeCS-red-ext, a sample that includes several clusters selected by X-ray flux or Sunyaev-Zeldovich signal. The heterogeneous sample of 121 clusters in HeCS-red-ext shows similar intrinsic scatter in the {sigma}p-{lambda} relation as the HeCS-red sample, but the range of {sigma}p at fixed richness increases to 3x. We evaluate the membership probability estimates Pmem for individual galaxies provided by redMaPPer. The spectroscopic membership fraction is larger than Pmem for 0.05<=P_mem_<=0.7; conversely, the spectroscopic membership fraction is smaller than P_mem_ at P_mem_>=0.8. We compare spectroscopic richness estimates with redMaPPer richness estimates and find good agreement on average, but a range of a factor of two in spectroscopic richness at fixed redMaPPer richness. Overall, within the high-richness and low-redshift cut of our sample, spectroscopically estimated parameters such as velocity dispersion correlate well with photometric richness estimates, although the relations contain substantial scatter.2018ApJ...862..172Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/862/172CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/267 : The SDSS Photometric Catalog, Release 4 (Adelman-McCarthy+, 2006)VIII/91 : Planck Catalog of Compact Sources Release 1 (Planck, 2013)J/ApJ/471/694 : Abell 2390 Gunn photometry & equivalent widths (Abraham+ 1996)J/ApJ/511/65 : Einstein images of galaxy clusters (Jones & Forman, 1999)J/AJ/126/2152 : Cluster And Infall Region Nearby Survey.
