Abstract (from CDS):

We present analysis of the optical and X-ray spectra of the low Galactic latitude bright (F2–10=3.6x10–11erg/cm2/s) source u. On the basis of the optical data we propose to classify u as an intermediate type Seyfert galaxy and we measure a value of z=0.012±0.001 for its redshift. From the XMM-Newton observation we find that the overall X-ray spectral shape of u is complex and can be described by a power-law continuum (Γ≃1.55) obscured by two neutral absorption components (NHf∼1022cm–2 and NHp∼4x1022cm–2), the latter covering only the ∼50% of the primary X-ray source. The X-ray data therefore lend support to our classification of u. It exhibits a broad and skewed Fe Kα line at ∼6.4keV, which suggests the existence of an accretion disk that is able to reprocess the primary continuum down to a few gravitational radii. Such a line represents one of the clearest examples of a relativistic line observed by XMM-Newton so far. Our analysis has also revealed the marginal presence of two narrow line-like emission features at ∼4.9 and ∼5.2keV.
