THE JET-LAUNCHING DISK AND ACCRETION FLOW IN CENTAURUS A
A full understanding of the AGN that drive the most powerful jets - those that reshape clusters and galaxies - requires that we study the accretion disk in such systems. However, in most cases, the accretion inflow is obscured, hidden, or otherwise inaccessible. Cen A is a nearby radio galaxy (d=3.8 Mpc) with dramatic bipolar jets; it is the brightest such galaxy in the 4-10~keV band, and its spectra show the strongest narrow Fe~Ka emission line among radio-loud AGN. It is possible to associate the narrow Fe line with the elusive optical BLR, and some spectra hint at ultra-fast, v~0.1c winds. Resolve spectroscopy of Cen A will reveal the inner and intermediate disk in the jet mode, and reveal the properties of slow and ultra-fast disk winds.
