Scientific paper

We propose a 180 ks Chandra METG/HETG observation of the heavily absorbed Seyfert 2 galaxy NGC 4945; this is a follow-up to our imaging observation from AO-1. Our goals are: (1) to study the spectrum of the nucleus (and specifically, the profile of the Fe K line which dominates there) to determine the geometry of the innermost nuclear region around the AGN, and (2) to obtain high resolution spectrum of the slighly extended (10"x20") "plume" emanating from the nucleus (in the direction perpendicular to the plane of the galaxy disk), to determine the heating mechanism of the gas in the "plume."
