Forming Early-type Galaxies in Groups Prior to Cluster Assembly
Stefan J. Kautsch, Anthony H. Gonzalez, Christian A. Soto +3
We study a unique proto-cluster of galaxies, the supergroup SG1120-1202. We quantify the degree to which morphological transformation of cluster galaxies occurs prior to cluster as…
Constraining the Scatter in the Mass-Richness Relation of maxBCG Clusters With Weak Lensing and X-ray Data
Eduardo Rozo, Eli S. Rykoff, August Evrard +10
We measure the logarithmic scatter in mass at fixed richness for clusters in the maxBCG cluster catalog, an optically selected cluster sample drawn from SDSS imaging data. Our meas…
Generation of Vorticity and Velocity Dispersion by Orbit Crossing
Sebastian Pueblas, Roman Scoccimarro
We study the generation of vorticity and velocity dispersion by orbit crossing using cosmological numerical simulations, and calculate the backreaction of these effects on the evol…
The Dark Energy Survey Data Management System
Joseph J. Mohr, Wayne Barkhouse, Cristina Beldica +17
The Dark Energy Survey collaboration will study cosmic acceleration with a 5000 deg2 griZY survey in the southern sky over 525 nights from 2011-2016. The DES data management (DESDM…
Detectability of Gravitational Waves from Phase Transitions
Tina Kahniashvili, Arthur Kosowsky, Grigol Gogoberidze +1
Gravitational waves potentially represent our only direct probe of the universe when it was less than one second old. In particular, first-order phase transitions in the early univ…
The Late Stellar Assembly of Massive Cluster Galaxies Via Major Merging
Kim-Vy H. Tran, John Moustakas, Anthony H. Gonzalez +3
We present multi-wavelength observations of the brightest galaxies in four X-ray luminous groups at z~0.37 that will merge to form a cluster comparable in mass to Coma. Ordered by…
