Abstract (from CDS):

This paper reports on a partially simultaneous observation of the bright Seyfert 1 Galaxy Mrk 590, performed by XMM-Newton and Chandra. The long exposure (∼100ks) allows us to investigate the FeK complex at 6-7keV and the presence of soft X-ray spectral features in great detail. We have analysed XMM-Newton data from the European Photon Imaging Camera (EPIC) in the 0.5-12keV band and from the Reflection Grating Spectrometer (RGS) in the 0.35-2.5keV band, and data from the High Energy Transmission Gratings (HETGs) onboard Chandra. UV and optical data from the Optical Monitor (OM) onboard XMM-Newton are also included in the analysis. The broad band spectrum is well described by an unabsorbed power law and three unresolved Fe K lines in the 6-7keV range. The presence of a Compton reflection component and a narrow Fe K line at 6.4keV is consistent with an origin via torus reflection. The ionised Fe lines at ∼6.7 and 7keV are instead most likely originated by scattering on a warm and ionised gas. The soft X-ray spectrum appears to be almost featureless due to the very bright continuum emission, except for one emission line identified as OVIII Lyα detected at ∼19Å by both RGS and Chandra-MEG. The emerging picture consists of an active nucleus seen directly on a ``clean'' line of sight without intervening material, surrounded by photoionised circumnuclear gas at a high ionisation level. We also study three serendipitous sources in the field of view of Chandra and XMM-Newton. One of these sources may be identified with an ULX of L0.3–10keV∼4x1040erg/s.
