Galaxy cluster X-ray luminosity scaling relations from a representative local sample (REXCESS)
We examine the X-ray luminosity scaling relations of 31 nearby galaxy clusters from the Representative XMM-Newton Cluster Structure Survey (REXCESS). The objects are selected only in X-ray luminosity, optimally sampling the cluster luminosity function. Temperatures range from 2 to 9 keV, and there is no bias toward any particular morphological type. To reduce measurement scatter we extract pert...
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 کاملCenter-Excised X-ray Luminosity as an Efficient Mass Proxy for Future Galaxy Cluster Surveys
The cosmological constraining power of modern galaxy cluster catalogs can be improved by obtaining low-scatter mass proxy measurements for even a small fraction of sources. In the context of large upcoming surveys that will reveal the cluster population down to the group scale and out to high redshifts, efficient strategies for obtaining such mass proxies will be valuable. In this work, we use ...
متن کاملGravitating mass profiles of nearby galaxy clusters and relations with X-ray gas temperature, luminosity and mass
We consider a sample of 22 nearby clusters of galaxies observed with the Medium Energy Concentrator Spectrometer (MECS) on board of BeppoSAX . They cover the range in gas temperature between 3 and 10 keV, with bolometric Xray luminosity between 2× 10 erg s−1 and 6× 10 erg s−1. Using the de-projected gas temperature and density profiles resolved in a number of bins between 5 and 7 and obtained f...
متن کاملEvolution of the K-band Galaxy Cluster Luminosity Function and Scaling Relations
We study the evolution of two fundamental properties of galaxy clusters: the luminosity function (LF) and the scaling relations between the total galaxy number N (or luminosity) and cluster mass M. Using a sample of 27 clusters (0 ≤ z ≤ 0.9) with new near-IR observations and mass estimates derived from X–ray temperatures, in conjunction with data from the literature, we construct the largest sa...
