Iras 13197-1627, Xmm-Newton Proposal 02065801

Scientific paper

We request a 40 ks XMM-Newton observation of the nearby Sy 2 galaxy IRAS 13197-1627. Previous BeppoSAX observations have shown that this source is X-ray bright [F(2-10 keV)~4x10e-12 erg/s/cm2] and absorbed (Nh>1e24 cm-2) implying a luminosity of L(2-10 keV)>2x1e44 erg/s, i.e. it is the nearest and brightest type-II QSO. The BeppoSAX spectrum also exhibits complex spectral features that point to different physical interpretations that cannot be disentangled. Moreover, it shows interesting analogies with the most recent findings on NLSY1s. Our goals are to use the unique throughput of XMM-Newton to further investigate:i)the possible presence of a relativistic line in this type-II QSO;ii)its time resolved properties;iii)the nature of the ~7 keV absorption line.
