Scientific paper

We propose to add 70ks of Chandra GTO HETGS time (through Canizares) to the approved 80ks Chandra--HST observation of the Seyfert galaxy NGC 7469 (PI: Kriss). This will nearly double the number counts in the HETGS spectrum, improving S/N on emission and absorption lines and revealing weaker lines from the intrinsic absorber in this source. This will allow a better determination of the column densities vs. ionization state, resolve any separate kinematic components, and look for evidence of any collisionally ionized (versus photoionized) material. Understanding the circumnuclear absorbing gas and its influence on the radiation escaping from AGN has additional important implications for the radiative input to the IGM and the origins of the X-ray background.
