Scaling relations and X-ray properties of moderate-luminosity galaxy clusters from 0.3<z<0.6 with XMM-Newton. Connor T., Donahue M., Sun M., Hoekstra H., Mahdavi A., Conselice C.J., McNamara B. <Astrophys. J., 794, 48 (2014)> =2014ApJ...794...48C (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, galaxy ; X-ray sources ; Redshifts Keywords: galaxies: clusters: general - X-rays: galaxies: clusters Abstract: We present new X-ray temperatures and improved X-ray luminosity estimates for 15 new and archival XMM-Newton observations of galaxy clusters at intermediate redshift with mass and luminosities near the galaxy group/cluster division (M2500<2.4x1070-1M, L<2x1044erg/s, 0.3<z<0.6). These clusters have weak-lensing mass measurements based on Hubble Space Telescope observations of clusters representative of an X-ray-selected sample (the ROSAT 160SD survey). The angular resolution of XMM-Newton allows us to disentangle the emission of these galaxy clusters from nearby point sources, which significantly contaminated previous X-ray luminosity estimates for 6 of the 15 clusters. We extend cluster scaling relations between X-ray luminosity, temperature, and weak-lensing mass for low-mass, X-ray-selected clusters out to redshift ∼0.45. These relations are important for cosmology and the astrophysics of feedback in galaxy groups and clusters. Our joint analysis with a sample of 50 clusters in a similar redshift range but with larger masses (M500<21.9x1014M, 0.15≤z≤0.55) from the Canadian Cluster Comparison Project finds that within r2500, M∝L0.44±0.05, T∝L0.23±0.02, and M∝T1.9±0.2. The estimated intrinsic scatter in the M-L relation for the combined sample is reduced to σlog(M|L)=0.10, from σlog(M|L)=0.26 with the original ROSAT measurements. We also find an intrinsic scatter for the T-L relation, σlog(T|L)=0.07±0.01. Description: Our sample is based on 25 galaxy clusters first detected in the ROSAT 160 Square Degree Survey. Vikhlinin et al. (1998, J/ApJ/502/558) describe the initial survey, and a reanalysis with spectroscopic redshifts comes from Mullis et al. (2003, J/ApJ/594/154). These 25 clusters were further studied with an HST snapshot program (PI: Donahue) of one orbit per cluster with the F814W filter. Due to the nature of the snapshot program, the clusters were randomly selected from a master list of 72 clusters. We searched the archive of XMM-Newton observations with the XMM-Newton Science Archive (XSA) v7.2 within a 15' radius of the cluster positions given in Hoekstra et al. (2011ApJ...726...48H). As of 2013 June 28, we found 27 observations that included the cluster. All observations were taken with the European Photon Imaging Camera (EPIC), which consists of two MOS cameras (Turner et al. 2001A&A...365L..27T) and the pn camera (Struder et al. 2001A&A...365L..18S).
