Chandra Detection of the Iron Compton Shoulder in the Circinus Galaxy
Abstract
We report on the detection of the iron Kalpha Compton shoulder with a flux of about 20% the line core in the Chandra HEG spectrum of the Circinus Galaxy. This feature is predicted on theoretical grounds as arising from Compton scattering of the fluorescent line photons in optically thick matter, and the observed flux and width are fully consistent with Monte Carlo simulations, which are also presented here.
