Mass Accretion Rates of the HectoMAP Clusters of Galaxies.

PIZZARDO M., SOHN J., GELLER M.J., DIAFERIO A. and RINES K.

Abstract (from CDS):

We estimate the mass accretion rate (MAR) of 321 clusters of galaxies in the HectoMAP Cluster Survey. The clusters span the redshift range 0.17-0.42 and the M 200 mass range ≃ (0.5-3.5) x 1014 M ☉. The MAR estimate is based on the caustic technique along with a spherical infall model. Our analysis extends the measurement of MARs for 129 clusters at z < 0.3 from the Cluster Infall Regions in the Sloan Digital Sky Survey and the Hectospec Cluster Survey to redshift z ∼ 0.42. Averaging over redshift, low-mass clusters with masses near 0.7 x 1014 M ☉ roughly accrete 3 x 104 M ☉ yr–1; more massive clusters with masses near 2.8 x 1014 M ☉ roughly accrete 1 x 105 M ☉ yr–1. Low- and high-mass clusters increase their MAR by approximately 46% and 84%, respectively, as the redshift increases from z in the range 0.17-0.29 to z in the range 0.34-0.42. The MARs at fixed redshift increase with mass and MARs at fixed mass increase with redshift in agreement with the ΛCDM cosmological model for hierarchical structure formation. We consider the extension of MAR measurements to z ∼ 1.
