The eleventh and twelfth data releases of the Sloan Digital Sky Survey: final data from SDSS-III
The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical
redMaPPer I: Algorithm and SDSS DR8 Catalog
We describe redMaPPer, a new red sequence cluster finder specifically designed to make optimal use of ongoing and near-future large photometric surveys. The algorithm has multiple attractive
A spectroscopically confirmed X-ray cluster at z = 1.62 with a possible companion in the Subaru/XMM-Newton deep field
We report on a confirmed galaxy cluster at z = 1.62. We discovered two concentrations of galaxies at z ~ 1.6 in the Subaru/XMM-Newton deep field based on deep multi-band photometric data. We made a
The Chandra COSMOS Survey. I. Overview and Point Source Catalog
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra program that has imaged the central 0.5 deg^2 of the COSMOS field (centered at 10 ^h , +02 ^o ) with an effective exposure of ~160 ks,
A mature cluster with X-ray emission at z = 2.07
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 emission detected
The Chandra Deep Field-South Survey: 2 Ms Source Catalogs
We present point-source catalogs for the ≈2 Ms exposure of the Chandra Deep Field-South (CDF-S); this is one of the two most sensitive X-ray surveys ever performed. The survey covers an area of ≈436
Details of the mass-temperature relation for clusters of galaxies
We present results on the total mass and temperature determination using two samples of clusters of galaxies. One sample is constructed with emphasis on the completeness of the sample, while the
Stellar and Total Baryon Mass Fractions in Groups and Clusters Since Redshift 1
We investigate if the discrepancy between estimates of the total baryon mass fraction obtained from observations of the cosmic microwave background (CMB) and of galaxy groups/clusters persists when a
The Birmingham-CfA cluster scaling project - III. Entropy and similarity in galaxy systems
We examine profiles and scaling properties of the entropy of the intergalactic gas in a sample of 66 virialized systems, ranging in mass from single elliptical galaxies to rich clusters, for which we
The XMM-Newton wide-field survey in the COSMOS field - The point-like X-ray source catalogue
Context. The COSMOS survey is a multiwavelength survey aimed to study the evolution of galaxies, AGN and large scale structures. Within this survey XMM-COSMOS a powerful tool to detect AGN and
