An Improved Cluster Richness Estimator
Eduardo Rozo, Eli S. Rykoff, Benjamin P. Koester +11
Minimizing the scatter between cluster mass and accessible observables is an important goal for cluster cosmology. In this work, we introduce a new matched filter richness estimato…
Cross-correlation Weak Lensing of SDSS galaxy Clusters II: Cluster Density Profiles and the Mass--Richness Relation
David E. Johnston, Erin S. Sheldon, Risa H. Wechsler +7
We interpret and model the statistical weak lensing measurements around 130,000 groups and clusters of galaxies in the Sloan Digital Sky Survey presented by Sheldon et al. 2007 (Pa…
Optically-Selected Cluster Catalogs as a Precision Cosmology Tool
Eduardo Rozo, Risa H. Wechsler, Benjamin P. Koester +2
We introduce a framework for describing the halo selection function of optical cluster finders. We treat the problem as being separable into a term that describes the intrinsic gal…
Cosmological Constraints from SDSS maxBCG Cluster Abundances
Eduardo Rozo, Risa H. Wechsler, Benjamin P. Koester +6
We perform a maximum likelihood analysis of the cluster abundance measured in the SDSS using the maxBCG cluster finding algorithm. Our analysis is aimed at constraining the power s…
