Journal ArticleDOI

TL;DR: In this article, a self-organizing map is proposed to map the distribution of data in a high-dimensional space and projecting it onto a lower-dimensional representation, which can be used to estimate the additional spectroscopy needed to map out the color-redshift relation.
Journal ArticleDOI

TL;DR: The Kilo-Degree Survey is an optical wide-field survey designed to map the matter distribution in the Universe using weak gravitational lensing as mentioned in this paper, which is used to measure the density profiles and masses of a sample of ∼1400 spectroscopically identified galaxy groups and clusters from the Galaxy And Mass Assembly survey.
Journal ArticleDOI

TL;DR: In this paper, the authors present new constraints on the relationship between galaxies and their host dark matter haloes, measured from the location of the peak of the stellar-to-halo mass ratio (SHMR), up to the most massive galaxy clusters at redshift z ∼ 0.8 and over a volume of nearly 0.1 Gpc3.

TL;DR: In this paper, the authors presented a quantitative analysis of the largest contiguous maps of projected mass density obtained from gravitational lensing shear using data from the 154'deg^2 covered by the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS).

TL;DR: In this paper, the authors present cosmological constraints using tomographic weak gravitational lensing by large-scale structure, and demonstrate that the redshift probability distribution function summed over galaxies provides an accurate representation of the galaxy redshift distribution accounting for random and catastrophic errors.
