Title

THE ORIGIN OF THE FE KA LINE IN THE BRIGHT SEYFERT 2 NGC 4507

Abstract

NCG 4507 is one of the X-ray brightest, but highly obscured, Seyfert 2 galaxies. It has been observed several times in the X-ray band, and it has always shown a strong iron K emission line. NCG 4507 is one of the few Compton thin AGN with a clear detection of the Ni Ka emission line. Iron K absorption lines have also been detected, suggesting the presence of an ionized absorber, possibly outflowing. The proposed 100 ksec XRISM observation will allow us to resolve with unprecedented precision the origin of the Fe K emission and absorption lines. Thanks to the high spectral resolution offered by Resolve any contribution from a BLR-Fe Ka will be fully revealed.
