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…
