J/ApJ/649/730    ULX population in nearby galaxies from XMM    (Winter+, 2006)

XMM-Newton archival study of the ultraluminous X-ray population in nearby galaxies. Winter L.M., Mushotzky R.F., Reynolds C.S. <Astrophys. J., 649, 730-752 (2006)> =2006ApJ...649..730W
ADC_Keywords: Surveys ; Galaxies, nearby ; X-ray sources Keywords: accretion, accretion disks - galaxies: general - surveys - X-rays: binaries Abstract: We present the results of an archival XMM-Newton study of the bright X-ray point sources (LX>1038ergs/s) in 32 nearby galaxies. From our list of approximately 100 point sources, we attempt to determine if there is a low-state counterpart to the ultraluminous X-ray (ULX) population, searching for a soft-hard state dichotomy similar to that known for Galactic X-ray binaries and testing the specific predictions of the intermediate-mass black hole (IMBH) hypothesis. To this end, we searched for low-state objects, which we defined as objects within our sample that had a spectrum well fitted by a simple absorbed power law, and high-state objects, which we defined as objects better fitted by a combined blackbody and a power law. Description: The data used in this investigation were drawn from the XMM-Newton public data archive. File Summary:

Source identified as [WMR2006] Galaxy Source in Simbad Note (2): Flag on name as follows: 5 = Transient 8 = Spectra too scattered to model 9 = bright sources coincide with nucleus (unresolvable star cluster and X-ray binaries), fore-ground star, and background AGN (Martin, Kobulnicky, Heckman (2002ApJ...574..663M) 12 = bright source is too close to other sources 15 = Unable to model sprectrum due to an error in χ2-space 16 = bright sources are too close, but resolvable by Chandra (Summers et al., 2004MNRAS.351....1S) 18 = bright sources near the nucleus are unresolvable, but seen by Chandra (Smith & Wilson, 2001ApJ...557..180S) Note (3): Flag on ID as follows: 4 = identification for NGC0253 following Humphrey et al. (2003, Cat. J/MNRAS/344/134). 10 = IXO designation from Colbert & Ptak (2002, Cat. J/ApJS/143/25). 11 = spectrum from Hol IX observation. 13 = Chandra observations of point sources in NGC4449 published in Summers et al. (2003MNRAS.342..690S); Source 27 varied from ROSAT observations 14 = three other sources near the nucleus are unresolvable in the XMM obs., but seen by Chandra (Eracleous et al., 2002ApJ...565..108E). 17 = alternate ID from Jenkins et al.
