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…
Biases in the Gravitational Lens Population Induced by Halo and Galaxy Triaxiality
Eduardo Rozo, Jacqueline Chen, Andrew R. Zentner
The lensing cross section of triaxial halos depends on the relative orientation between a halo's principal axes and its line of sight. Consequently, a lensing subsample of randomly…
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…
