Measuring the Mean and Scatter of the X‐Ray Luminosity–Optical Richness Relation for maxBCG Galaxy Clusters
Measuring the Mean and Scatter of the X‐Ray Luminosity–Optical Richness Relation for maxBCG Galaxy Clusters
Determining the scaling relations between galaxy cluster observables requires large samples of uniformly observed clusters. We measure the mean X-ray luminosity--optical richness (L_X--N_200) relation for an approximately volume-limited sample of more than 17,000 optically-selected clusters from the maxBCG catalog spanning the redshift range 0.1
