Galaxy cluster X-ray luminosity scaling relations from a representative local sample (REXCESS)
Böhringer, H.; Arnaud, M.; Pratt, G. W. +1 more
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 typ…
The XMM-Newton serendipitous survey. V. The Second XMM-Newton serendipitous source catalogue
Pietsch, W.; Motch, C.; Brusa, M. +47 more
Aims: Pointed observations with XMM-Newton provide the basis for creating catalogues of X-ray sources detected serendipitously in each field. This paper describes the creation and characteristics of the 2XMM catalogue.
Methods: The 2XMM catalogue has been compiled from a new processing of the XMM-Newton EPIC camera data. The main features of t…
The XMM-Newton wide-field survey in the COSMOS field. The point-like X-ray source catalogue
Finoguenov, A.; Böhringer, H.; Salvato, M. +24 more
Context: The COSMOS survey is a multiwavelength survey aimed to study the evolution of galaxies, AGN and large scale structures. Within this survey XMM-COSMOS a powerful tool to detect AGN and galaxy clusters. The XMM-COSMOS is a deep X-ray survey over the full 2 deg2 of the COSMOS area. It consists of 55 XMM-Newton pointings for a tota…
CAIXA: a catalogue of AGN in the XMM-Newton archive. I. Spectral analysis
Bianchi, S.; Ponti, G.; Guainazzi, M. +2 more
Aims: We present CAIXA, a Catalogue of AGN In the XMM-Newton Archive. It consists of all the radio-quiet X-ray unobscured (N_H<2×1022 cm-2) active galactic nuclei (AGN) observed by XMM-Newton in targeted observations, whose data are public as of March 2007. With its 156 sources, this is the largest catalogue of high signal…
An X-ray view of 82 LINERs with Chandra and XMM-Newton data
Guainazzi, M.; Jiménez-Bailón, E.; González-Martín, O. +2 more
We present the results of a homogeneous X-ray analysis for 82 nearby low-ionisation, narrow emission-line regions (LINERs) selected from the catalogue of Carrillo et al. (1999, Rev. Mex. Astron. Astrofis., 35, 187). All sources have available Chandra (68 sources) and/or XMM-Newton (55 sources) observations. This is the largest sample of LINERs wit…
The bolometric luminosity of type 2 AGN from extinction-corrected [OIII]. No evidence of Eddington-limited sources
Perola, G. C.; Bianchi, S.; Barcons, X. +3 more
Context: There have been recent claims that a significant fraction of type 2 AGN accrete close to or even above the Eddington limit. In type 2 AGN, the bolometric luminosity (L_b) is generally inferred from the [OIII] emission line luminosity (L_OIII). The key issue in estimating the bolometric luminosity in these AGN, is therefore to know the bol…
Hot stars observed by XMM-Newton. I. The catalog and the properties of OB stars
Nazé, Y.
Aims: Following the advent of increasingly sensitive X-ray observatories, deep observations of early-type stars became possible. However, the results for only a few objects or clusters have until now been reported and there has been no large survey comparable to that based upon the ROSAT All-Sky Survey (RASS).
Methods: A limited survey of X-ra…
The second INTEGRAL AGN catalogue
Mas-Hesse, J. M.; Gehrels, N.; Ricci, C. +7 more
Aims: The INTEGRAL mission provides a large data set for studying the hard X-ray properties of AGN and allows testing of the unified scheme for AGN.
Methods: We present analysis of INTEGRAL IBIS/ISGRI, JEM-X, and OMC data for 199 AGN supposedly detected by INTEGRAL above 20 keV.
Results: The data analysed here allow significant spectral ex…
Chemical enrichment in the cluster of galaxies Hydra A
Finoguenov, A.; Böhringer, H.; Simionescu, A. +4 more
We analyzed global properties, radial profiles, and 2D maps of the metal abundances and temperature in the cool core cluster of galaxies Hydra A using a deep ~120 ks XMM-Newton exposure. The best fit among the available spectral models is provided by a Gaussian distribution of the emission measure (gdem). We can accurately determine abundances for…
The XMM-Newton serendipitous survey. VI. The X-ray luminosity function
Silverman, J. D.; Ebrero, J.; Page, M. J. +6 more
Aims: To study the cosmological evolution of active galactic nuclei (AGN) is one of the main goals of X-ray surveys. To accurately determine the intrinsic (before absorption) X-ray luminosity function, it is essential to constrain the evolutionary properties of AGN and therefore the history of the formation of supermassive black holes with cosmic …
