Cross-correlation Weak Lensing of SDSS galaxy Clusters II: Cluster Density Profiles and the Mass--Richness Relation

TL;DR: In this article, a non-parametric inversion of the 2D shear profiles to the mean 3D cluster density and mass profiles in bins of both optical richness and cluster i-band luminosity is presented.
Journal ArticleDOI

Dark Energy Survey Year 1 Results: The Photometric Data Set for Cosmology

I. Sevilla-Noarbe, +131 more
TL;DR: The Dark Energy Survey (DES) photometric data set Y3 GOLD as discussed by the authors contains nearly 5000 deg2 of grizY imaging in the south Galactic cap including nearly 390 million objects, with depth reaching a signal-to-noise ratio ∼10 for extended objects up to i AB ∼ 23.0, and top-of-the-atmosphere photometric uniformity 98% and purity >99% for galaxies with 19 < i AB < 22.5.
Journal ArticleDOI

The Connection between Galaxies and their Dark Matter Halos

TL;DR: In this paper, the authors define the galaxy-halo connection as the multi-variate distribution of galaxy and halo properties that can be derived from observations and simulations and highlight key open questions about how galaxies and halos are connected.
Journal ArticleDOI

CANDELS: The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey

Norman A. Grogin, +108 more
TL;DR: The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) as mentioned in this paper was designed to document the first third of galactic evolution, over the approximate redshift (z) range 8--1.5.
