J/A+A/495/733       XMM-Newton spectral survey of M31 disc        (Shaw+, 2009)

An X-ray spectral survey of the disc of M31 with XMM-Newton. Shaw Greening L., Barnard R., Kolb U., Tonkin C., Osborne J.P. <Astron. Astrophys., 495, 733-741 (2009)> =2009A&A...495..733S
ADC_Keywords: Galaxies, nearby ; X-ray sources Keywords: galaxies: individual: M 31 - X-rays: general - X-rays: binaries Abstract: We present the results of a complete spectral survey of the X-ray point sources detected in five XMM-Newton observations along the major axis of M 31 but avoiding the central bulge, aimed at establishing the population characteristics of X-ray sources in this galaxy. We obtained background subtracted spectra and lightcurves for each of the 335 X-ray point sources detected across the five observations from 2002. We also correlate our source list with those of earlier X-ray surveys and radio, optical and infra-red catalogues. Sources with more than 50 source counts are individually spectrally fit in order to create the most accurate luminosity functions of M 31 to date. Description: One observation of each disc field of M 31 was taken using the EPIC pn and MOS cameras on XMM-Newton in January and June 2002 File Summary:

Note (1): The best fit model to a source can be as follows: faint = less than 50 source counts (no Gamma/kT value) pl = power law (Gamma) bb = blackbody (kT) br = bremsstrahlung (kT) nsa = neutron star atmosphere (kT) diskbb = disk blackbody (kT) Note (2): Appropriate parameter (photon index, Gamma, or temperature, kT) of the best fit model Note (3): derived from the model parameters with 90% confidence; in 1036erg/s Note (4): Classifications as follows: fg Star = foreground star <fg Star> = foreground star candidate AGN = active galactic nucleus <AGN> = AGN candidate Gal = galaxy GCl = galaxy cluster <SSS> = supersoft source candidate in M 31 SNR = supernova remnant in M 31 <SNR> = supernova remnant candidate in M 31 GlC = source in globular cluster <GlC> = source in globular cluster candidate XRB = X-ray binary in M 31 <hard> = HR2-e_HR2>-0.2 or only HR3 and HR4 defined, and no other classification Note (5): Flag "a" for this work classification, else from [PFH2005] (Pietsch et al., 2005, Cat.
