redMaPPer I: Algorithm and SDSS DR8 Catalog
E. S. Rykoff, E. Rozo, M. T. Busha +12
We describe redMaPPer, a new red-sequence cluster finder specifically designed to make optimal use of ongoing and near-future large photometric surveys. The algorithm has multiple…
The SDSS Coadd: Cosmic Shear Measurement
Huan Lin, Scott Dodelson, Hee-Jong Seo +7
Stripe 82 in the Sloan Digital Sky Survey was observed multiple times, allowing deeper images to be constructed by coadding the data. Here we analyze the ellipticities of backgroun…
The SDSS Coadd: Cross-Correlation Weak Lensing and Tomography of Galaxy Clusters
Melanie Simet, Jeffrey M. Kubo, Scott Dodelson +7
The shapes of distant galaxies are sheared by intervening galaxy clusters. We examine this effect in Stripe 82, a 275 square degree region observed multiple times in the Sloan Digi…
The SDSS Coadd: A Galaxy Photometric Redshift Catalog
Ribamar R. R. Reis, Marcelle Soares-Santos, James Annis +7
We present and describe a catalog of galaxy photometric redshifts (photo-z's) for the Sloan Digital Sky Survey (SDSS) Coadd Data. We use the Artificial Neural Network (ANN) techniq…
Robust Optical Richness Estimation with Reduced Scatter
E. S. Rykoff, B. P. Koester, E. Rozo +7
Reducing the scatter between cluster mass and optical richness is a key goal for cluster cosmology from photometric catalogs. We consider various modifications to the red-sequence…
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…
