cds-question@unistra.frgalaxy-clustersvisible-astronomyspectroscopyredshiftedWe present a catalog of spectroscopic redshifts for SPT-CLJ0615-5746, the most distant cluster in the Reionization Lensing Cluster Survey. Using Nod & Shuffle multislit observations with LDSS-3 on Magellan, we identify ~50 cluster members and derive a cluster redshift of z_c_=0.972, with a velocity dispersion of {sigma}=1244+/-162km/s. We calculate a cluster mass using a {sigma}_200_-M_200_ scaling relation of M_200_=(9.6+/-3.5)x10^14^M_{sun}_, in agreement with previous, independent mass measurements of this cluster. In addition, we examine the kinematic state of SPT-CLJ0615-5746, taking into consideration prior investigations of this system. With an elongated profile in lensing mass and X-ray emission, a non-Gaussian velocity dispersion that increases with clustercentric radius, and a brightest cluster galaxy not at rest with the bulk of the system, there are multiple cluster properties that, while not individually compelling, combine to paint a picture that SPT-CLJ0615-5746 is currently being assembled.2019ApJ...878...66Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/878/66CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)J/ApJ/455/60 : CFRS II: 0000-00 and 1000+25 fields (Le Fevre+ 1995)J/ApJS/150/1 : VV29 and NGC 4676 HST photometry (Benitez+, 2004)J/AJ/132/926 : Galaxies in the Hubble Ultra Deep Field (Coe+, 2006)J/ApJS/199/25 : CLASH sources for MACS1149.6+2223 (Postman+, 2012)J/ApJ/792/76 : Lensed z~6-8 galaxies behind CLASH clusters (Bradley+, 2014)J/ApJS/211/21 : Spectroscopic redshifts of galaxies in MACS (Ebeling+, 2014)J/ApJS/216/27 : Galaxy clusters discovered in the SPT-SZ survey (Bleem+, 2015)J/MNRAS/452/1437 : Abell 2744 strong-lensing analysis (Jauzac+, 2015)J/ApJ/812/114 : Grism Lens-Amplified Survey from Space.
