A prominent relativistic iron line in the Seyfert 1 MCG-02-14-009.

PORQUET D.

Abstract (from CDS):

I report the discovery of a prominent broad and asymmetrical feature near 6.4keV in the Seyfert 1 MCG-02-14-009 (z=0.028) with XMM-Newton/EPIC. The present short X-ray observation (PN net exposure time ∼5ks) is the first one above 2keV for MCG-02-14-009. The feature can be explained by either a relativistic iron line around either a Schwarzschild (non-rotating) or a Kerr (rotating) black hole. If the feature is a relativistic iron line around a Schwarzschild black hole, the line energy is 6.51+0.21–0.12keV with an equivalent width of 631+259–243eV and that the inclination angle of the accretion disc should be less than 43°. A relativistically blurred photoionized disc model gives a very good spectral fit over the broad band 0.2-12keV energy range. The spectrum is reflection dominated and this would indicate that the primary source in MCG-02-14-009 is located very close to the black hole, where gravitational light bending effect is important (about 3-4R_ g_), and that the black hole may rapidly rotate.
