AGN Outflows, the tip of the Iceberg?X-ray Spectroscopy Workshop, Cambridge, MA, July 2007 Outflows in AGN Iron K-shell Absorption in Seyfert 1s. Absorption Variability in NGC 3516 A highly ionized outflow in NGC 3516 (Turner et al. 2007, in prep) Zones of gas can cover wide range of ionization Relativistic Outflow in PDS 456(Deep Suzaku Observation, 190ks, Feb 07) Fe K Absorption line variability in PG 1211+143 A high velocity outflow in IC4329a (Markowitz et al. 2006) Do the iron K outflows have to be fast? Origins of the Blue-shifted Fe K-shell Absorption Local (z=0) absorption, such as the WHIM or local hot bubble unlikely due to variability. In many cases the outflow velocity differs from the AGN recessional velocity Therefore likely intrinsic to AGN, via outflow. Lower velocity solutions have difficulty in fitting Fe K band data in physically realistic model. High velocity, high ionization outflow seems the most plausible solution Future calorimeter resolution (6 eV) spectra will provide a wealth of data at Fe K on high column density outflows. * Collaborators:- Jane Turner (UMBC/GSFC), Valentina Braito (JHU/GSFC), Alex Markowitz (JHU/GSFC), Ken Pounds (Leicester) James Reeves, Keele University, UK (Formerly at NASA/GSFC/JHU) (Outflow Schematic; Elvis 2000) Outflows (in the form of warm absorbers) are seen in the majority of nearby AGN. Typically velocities ( from a few 100 km/s to a 1000 km/s, which could carry a few solar masses per year (out to pc scales). In some higher luminosity AGN strong blue-shifted Fe K absorption features are seen above 7 keV - possible high v outflows at v~0.1c Such outflows can carry significant Kinetic power - equivalent to the bolometric output. Can provide feedback between BH/bulge mass in galaxy. MCG-6-30-15, Chandra/HETG (500ks) NGC 1365/XMM, (Risaliti et al. 2005) Column densities are high, 1023 cm-2. Can effect broad Fe K modeling. McKernan et al. (04, 05) suggested some such lines could arise locally, e.g. WHIM,
