cds-question@unistra.frgalaxy-clustersgalaxiesspectroscopyredshiftedWe present the first dynamical mass estimates and scaling relations for a sample of Sunyaev-Zel'dovich effect (SZE) selected galaxy clusters. The sample consists of 16 massive clusters detected with the Atacama Cosmology Telescope (ACT) over a 455deg^2^ area of the southern sky. Deep multi-object spectroscopic observations were taken to secure intermediate-resolution (R~700-800) spectra and redshifts for {approx}60 member galaxies on average per cluster. The dynamical masses M_200c_ of the clusters have been calculated using simulation-based scaling relations between velocity dispersion and mass. The sample has a median redshift z=0.50 and a median mass M_200c_~12x10^14^h_70_^-1^M_{sun}_ with a lower limit M_200c_~6x10^14^h_70_^-1^M_{sun}_, consistent with the expectations for the ACT southern sky survey. These masses are compared to the ACT SZE properties of the sample, specifically, the match-filtered central SZE amplitude {overline}{y_0_}, the central Compton parameter y_0_, and the integrated Compton signal Y_200c_, which we use to derive SZE-mass scaling relations. All SZE estimators correlate with dynamical mass with low intrinsic scatter (<~20%), in agreement with numerical simulations. We explore the effects of various systematic effects on these scaling relations, including the correlation between observables and the influence of dynamically disturbed clusters. Using the three-dimensional information available, we divide the sample into relaxed and disturbed clusters and find that ~50% of the clusters are disturbed. There are hints that disturbed systems might bias the scaling relations, but given the current sample sizes, these differences are not significant; further studies including more clusters are required to assess the impact of these clusters on the scaling relations.2013ApJ...772...25Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/772/25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/88 : Planck Early Release Compact Source Catalogue (Planck, 2011)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/MNRAS/439/1556 : ACT high significance 148 & 218GHz sources (Marsden+, 2014)J/ApJ/771/137 : WMAP observations of Planck ESZ clusters (Ma+, 2013)J/ApJ/763/127 : Galaxy clusters in the SPT survey (Reichardt+, 2013)J/ApJ/731/100 : 148GHz ACT extragalactic sources catalog (Marriage+, 2011)J/ApJS/191/340 : Southern Cosmology Survey.
