Chandra Observations of Excess Fe K Line Emission in Galaxies with High Star Formation Rates: X-ray Reflection on Galaxy Scales?

Wei Yan, Ryan C. Hickox, Chien-Ting J. Chen +4

In active galactic nuclei (AGN), fluorescent Fe K (iron) line emission is generally interpreted as originating from obscuring material around a supermassive black hole (SMBH) on…
