Lensed Type Ia Supernovae as Probes of Cluster Mass Models
J. Nordin, D. Rubin, J. Richard +19
Using three magnified Type Ia supernovae (SNe Ia) detected behind CLASH clusters, we perform a first pilot study to see whether standardizable candles can be used to calibrate clus…
Exploiting Cross Correlations and Joint Analyses
J. Rhodes, S. Allen, B. A. Benson +12
In this report, we present a wide variety of ways in which information from multiple probes of dark energy may be combined to obtain additional information not accessible when they…
redMaPPer II: X-ray and SZ Performance Benchmarks for the SDSS Catalog
Eduardo Rozo, Eli S. Rykoff
We evaluate the performance of the SDSS DR8 redMaPPer photometric cluster catalog by comparing it to overlapping X-ray and SZ selected catalogs from the literature. We confirm the…
Cluster Cosmology at a Crossroads: Neutrino Masses
Eduardo Rozo, Eli S. Rykoff, James G. Bartlett +1
Galaxy clusters --- in combination with CMB and BAO data --- can provide precise constraints on the sum of neutrino masses. However, these constraints depend on the calibration of…
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…
