Dust lanes, thick absorbers, and the unification model for Seyfert galaxies
Received 4 January 2000 / Accepted 20 February 2000
A modification of the popular unification model for Seyfert galaxies is proposed, which takes into account recent observational findings on the statistical properties of both type 1 and type 2 Seyferts.
In the proposed scenario, Compton-thick Seyfert 2 galaxies are those sources observed through compact, thick matter (the `torus'), while Compton-thin/ intermediate Seyfert galaxies are obscured by dust lanes at larger distances.
Key words: galaxies: Seyfert X-rays: galaxies
