cds-question@unistra.frredshiftedgalaxy-clustersgravitational-lensingspectroscopygalaxy-kinematicsWe present results from a spectroscopic program targeting 26 strong-lensing cluster cores that were visually identified in the Sloan Digital Sky Survey (SDSS; Gladders et al. 2011, in prep) and the Second Red-Sequence Cluster Survey (RCS-2; Bayliss et al. 2011, in prep). The 26 galaxy cluster lenses span a redshift range of 0.2<z<0.65, and our spectroscopy reveals 69 unique background sources with redshifts as high as z=5.200. We also identify redshifts for 262 cluster member galaxies and measure the velocity dispersions and dynamical masses for 18 clusters where we have redshifts for N>=10 cluster member galaxies. We account for the expected biases in dynamical masses of strong-lensing-selected clusters as predicted by results from numerical simulations and discuss possible sources of bias in our observations.2011ApJS..193....8Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/193/8CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)IX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)VII/110 : Rich Clusters of Galaxies (Abell+ 1989)J/MNRAS/406/1318 : Lensed-arc statistics of galaxy clusters (Horesh+, 2010)J/ApJ/690/670 : The Sloan lens ACS Survey.
