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 (L̄X–N̄200) 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 < z < 0.3. By stacking the X-ray emission from many c...
متن کاملThe optical/X-ray connection: intra-cluster medium iron content and galaxy optical luminosity in 20 galaxy clusters
X-ray observations of galaxy clusters have shown that the intra-cluster gas has iron abundances of about one-third of the solar value. These observations also show that part (if not all) of the intra-cluster gas metals was produced within the member galaxies. We present a systematic analysis of 20 galaxy clusters to explore the connection between the iron mass and the total luminosity of earlya...
متن کاملCluster X - ray Luminosity Evolution
Whether the X-ray luminosities of clusters of galaxies evolve has been a contentious issue for over ten years. However, the data available to addresss this issue have improved dramatically as cluster surveys from the ROSAT archive near completion. There are now three samples of nearby clusters and seven distant cluster samples. We present a uniform analysis of four of the distant cluster sample...

متن کاملThe Lx −yx Relation: Using Galaxy Cluster X-ray Luminosity as a Robust, Low Scatter Mass Proxy
We use a sample of 115 galaxy clusters at 0.1 < z < 1.3 observed with Chandra ACIS-I to investigate the relation between luminosity and YX (the product of gas mass and temperature). The scatter in the relation is dominated by cluster cores, and a tight LX −YX relation (11% intrinsic scatter in LX) is recovered if sufficiently large core regions (0.15R500) are excluded. The intrinsic scatter is ...
