A broad-line region origin for the iron Kα line in NGC 7213
A broad-line region origin for the iron Kα line in NGC 7213
The X-ray spectrum of NGC7213 is known to present no evidence for Compton reflection, a unique result among bright Seyfert 1s. The observed neutral iron K$α$ line, therefore, cannot be associated with a Compton-thick material, like the disc or the torus, but is due to Compton-thin gas, with the Broad …
