Detection of the Fe K lines from the binary AGN in 4C+37.11

We report the discovery of the Fe K line emission at approximately 6.62 keV with a width of approximately 0.19 keV using two epochs of Chandra archival data from the nucleus of the galaxy 4C+37.11, which is known to host a binary supermassive black hole (BSMBH) system where the SMBHs are separated by approximately 7 milliarcseconds, or about 7 parsecs.
