XMM-Newton observations of an absorbed z=0.67 QSO: no dusty torus?

I. Georgantopoulos, A. Georgakakis, G. C. Stewart +4

We present XMM-Newton observations of AXJ0341.4-4453, a mildly reddened A_V<7 QSO at a redshift of z=0.672. The XMM-Newton spectrum shows a large obscuring column N_H~10^23 cm^{-2}…
