Revealing the nature of the extreme blueshifted iron line profile in PG1402+261

We propose to observe the NLS1 PG 1402+261 (at z0.164). A short 9ks observationrevealed an unusually strong (EW2keV) and very broad Fe K emission line. Theline centroid energy at 7.3 keV appears blueshifted with respect to the Fe Kaband, while the bluewing of the line extends to 9 keV. The line profile can befitted with reflection from a disk around a Kerr black hole, but requires aninclination in excess of 60 degrees, inconsistent with AGN unified models.Alternatively the spectrum may be explained by a large column density, highionization absorber from a powerful outflow. We propose for 2x50ks XMMNewtonobservations to distinguish between the disk reflection and outflow scenarios. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
