BeppoSAX observations of Mkn 3: Piercing through the torus of a Seyfert 2 galaxy
ASTRONOMY & ASTROPHYSICS, no. 3 (1999): 857-867
Abstract
A new BeppoSAX broad-band (0.6-150 keV) spectrum of the Seyfert 2 galaxy Mkn 3 is presented. The spectrum provides a direct measurement of a large, neutral column of gas with N-H similar to 10(24) cm(-2) in the source direction. The source, as bright as 3C 273 above 10 keV, has a steep (Gamma similar to 1.8) spectrum without any evidence ...More
