The origin of the iron lines in NGC 7213.

BIANCHI S., MATT G., BALESTRA I. and PEROLA G.C.

Abstract (from CDS):

The analysis of a simultaneous XMM-Newton/BeppoSAX plus three previous BeppoSAX observations revealed that NGC 7213 is a rather peculiar Seyfert 1. No significant Compton reflection component was observed, while an iron line complex, best explained in terms of three narrow lines, is clearly apparent in the data. Due to the absence of the reflection component, the neutral iron line is likely not produced in a Compton-thick material, but current data do not allow to choose between a Compton-thin torus and the BLR. The two ionized iron lines from FeXXV and FeXXVI may be produced in a photoionized gas with a column density of a few 1023cm–2, in analogy with the case of NGC 5506.
