Scientific paper

We propose to observe a sample of four Narrow Line Seyfert 1 galaxies with strong Fe II emission (FeNLS1s) for a total allocation time of 115 ks. The goal of this proposal is to test how common is the spectral hard X-ray (E~7-8 keV) absorption feature in FeNLS1s, recently observed in two objects of this class. This feature appears as a clear signature of dense matter outflowing from the nucleus. If our optically-based criterion (i.e. Fe II4570/Hbeta higher than 1.5) would be efficient in selecting objects with deep sharp X-ray edges, the origin of this feature in outflowing clouds would be supported. A frequent occurrence of this spectral drop will therefore provide clues of an intimate link between NLS1s and BAL QSOs phenomena.
