redMaPPer. I. ALGORITHM AND SDSS DR8 CATALOG
- E. Rykoff, E. Rozo, R. Wechsler
- Physics
- 14 March 2013
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 attractive…
Dark Energy Survey year 1 results: Cosmological constraints from galaxy clustering and weak lensing
- D. Abbott, F. Abdalla, J. Zuntz
- PhysicsPhysical Review D
- 4 August 2017
We present cosmological results from a combined analysis of galaxy clustering and weak gravitational lensing, using 1321 deg2 of griz imaging data from the first year of the Dark Energy Survey (DES…
A GMBCG GALAXY CLUSTER CATALOG OF 55,424 RICH CLUSTERS FROM SDSS DR7
- J. Hao, T. Mckay, E. Sheldon
- Physics
- 1 August 2010
We present a large catalog of optically selected galaxy clusters from the application of a new Gaussian Mixture Brightest Cluster Galaxy (GMBCG) algorithm to SDSS Data Release 7 data. The algorithm…
MaxBCG: A Red-Sequence Galaxy Cluster Finder
- B. Koester, T. Mckay, D. Johnston
- Physics
- 9 January 2007
Measurements of galaxy cluster abundances, clustering properties, and mass-to-light ratios in current and future surveys can provide important cosmological constraints. Digital wide-field imaging…
Cross-correlation Weak Lensing of SDSS galaxy Clusters II: Cluster Density Profiles and the Mass--Richness Relation
- D. Johnston, E. Sheldon, J. Annis
- Physics
- 9 September 2007
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). We present…
EIGHT NEW MILKY WAY COMPANIONS DISCOVERED IN FIRST-YEAR DARK ENERGY SURVEY DATA
- K. Bechtol, A. Drlica-Wagner, J. Zuntz
- Physics
- 9 March 2015
We report the discovery of eight new Milky Way companions in ∼ 1800 deg 2 ?> of optical imaging data collected during the first year of the Dark Energy Survey (DES). Each system is identified as a…
The DESI Experiment Part I: Science,Targeting, and Survey Design
- Desi Collaboration Amir Aghamousa, J. Aguilar, Y. Zu
- Physics
- 31 October 2016
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-space…
ROBUST OPTICAL RICHNESS ESTIMATION WITH REDUCED SCATTER
- E. Rykoff, B. Koester, R. Wechsler
- Physics
- 11 April 2011
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-matched filter…

CONSTRAINING THE SCATTER IN THE MASS–RICHNESS RELATION OF maxBCG CLUSTERS WITH WEAK LENSING AND X-RAY DATA
- E. Rozo, E. Rykoff, J. Frieman
- Physics
- 16 September 2008
We measure the logarithmic scatter in mass at fixed richness for clusters in the maxBCG cluster catalog, an optically selected cluster sample drawn from Sloan Digital Sky Survey imaging data. Our…
