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…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters III: Mass-to-light Ratios
Erin S. Sheldon, David E. Johnston, Morad Masjedi +8
We present measurements of the excess mass-to-light ratio measured aroundMaxBCG galaxy clusters observed in the SDSS. This red sequence cluster sample includes objects from small g…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters I: Measurements
Erin S. Sheldon, David E. Johnston, Ryan Scranton +12
This is the first in a series of papers on the weak lensing effect caused by clusters of galaxies in Sloan Digital Sky Survey. The photometrically selected cluster sample, known as…
The Dark Side of ROTSE-III Prompt GRB Observations
S. A. Yost, F. Aharonian, C. W. Akerlof +22
We present several cases of optical observations during gamma-ray bursts (GRBs) which resulted in prompt limits but no detection of optical emission. These limits constrain the pro…
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…
