The study of galaxy protoclusters is beginning to fill in unknown details of the important
phase of the assembly of clusters and cluster galaxies. This review describes the current …

Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it
can control the critical process of transforming galaxies from star forming to quiescent …

We report the identification of an extreme protocluster of galaxies in the early universe
whose core (nicknamed Distant Red Core, DRC, because of its very red color in Herschel …

Measurements of X-ray scaling laws are critical for improving cosmological constraints
derived with the halo mass function and for understanding the physical processes that …

ABSTRACT The South Pole Telescope (SPT) is currently surveying 2500 deg 2 of the
southern sky to detect massive galaxy clusters out to the epoch of their formation using the …

We report the discovery of a galaxy cluster at z= 1.62 located in the Spitzer Wide-Area
Infrared Extragalactic survey XMM–LSS field. This structure was selected solely as an …

We present a detailed analysis from new multi-wavelength observations of the exceptional
galaxy cluster ACT-CL J0102− 4915, likely the most massive, hottest, most X-ray luminous …

We report evidence of a fully established galaxy cluster at z= 2.07, consisting of a~ 20σ
overdensity of red, compact spheroidal galaxies spatially coinciding with extended X-ray …

We present the results of a search for galaxy clusters in the first 36 XMM-Newton pointings
on the Cosmic Evolution Survey (COSMOS) field. We reach a depth for a total cluster flux in …

We have identified 335 galaxy cluster and group candidates, 106 of which are at z> 1, using
a 4.5 μm-selected sample of objects from a 7.25 deg 2 region in the Spitzer Infrared Array …
