Scientific paper

We request a long 130ks XMM-Newton observation of the narrow-line Seyfert 1 galaxy IIZw177. The existing short 8.5ks XMM-Newton exposure has suggested a relativistically broadened iron K line with the red-wing extending down to 4.5keV in the EPIC-pn data. These data also suggest the presence of quasi-periodic oscillations (QPO) at 9e-4 Hz. The long observation can not only determine the relativistic disk emission line but also confirm the presence of QPO and allow us to search for PSD breaks, thus leading to unique and the only discovery of a broad line and QPO from the same AGN.
