Average AGN X-ray Spectrum


Date: 22 February 2005
Satellite: XMM-Newton
Depicts: Average X-ray spectrum of AGN in the X-ray background
Copyright: MPE

The light of about 100 distant active galaxies was first corrected to the rest frame of our Milky Way and then added together. Then a simple spectral model without lines was subtracted. The residual spectrum shows a strong, relativistically broadened iron line, which must originate from matter in the immediate vicinity of the black holes.
