One more surprise from the Circinus Galaxy: BeppoSAX discovery of a transmission component in hard X-rays
G. Matt, M. Guainazzi, R. Maiolino +11
The Circinus Galaxy has been observed, for the first time above 10 keV, by BeppoSAX. An excess emission above the extrapolation of the best fit 0.1--10 keV spectrum is apparent in…

A 3 dimensional diagnostic diagram for Seyfert 2s: probing X-ray absorption and Compton thickness
L. Bassani, M. Dadina, R. Maiolino +5
We present and discuss a "3-dimensional" diagnostic diagram for Seyfert2 galaxies obtained by means of X-ray and [OIII] data on a large sample of objects (reported in the Appendix)…

Heavy obscuration in X-ray weak AGNs
R. Maiolino, M. Salvati, L. Bassani +5
We present observations in the 0.1-100 keV spectral band of 8 Seyfert 2 galaxies, obtained by means of BeppoSAX. These sources were selected according to their [OIII] optical emiss…
