Journal ArticleDOI
The cluster abundance in flat and open cosmologies
TL;DR: In this article, the authors use the galaxy cluster X-ray temperature distribution function to constrain the am-plitude of the power spectrum of density inhomogeneities on the scale corresponding to clusters.

TL;DR: The redMaPPer algorithm as discussed by the authors was applied to 150 deg(2) of Science Verification (SV) data from the Dark Energy Survey (DES), and to the Sloan Digital Sky Survey (SDSS) DR8 photometric data set.

TL;DR: The largest uncertainty for cosmological studies using clusters of galaxies is introduced by our limited knowledge of the statistics of galaxy cluster structure, and of the scaling relations between observables and cluster mass as mentioned in this paper.
