The Cosmic History of Black Hole Growth from Deep Multiwavelength Surveys
Figure 4
Typical AGN X-ray spectrum from 0.1 to 100 keV. Each spectrum includes a power law with photon index , a Compton reflection hump, peaking at ~30 keV, a high-energy cutoff at 300 keV, and photoelectric absorption. Numbers for each curve indicate the amount of absorption, given as , with in units of atoms cm−2.
