Abstract: AGN outflows impact the evolution of super-massive black holes, host galaxies, surrounding IGM, and cluster cooling flows. However, while the theoretical interest in these outflows increased dramatically, we have only weak constraints on the most important properties of real AGN winds: kinetic luminosity, chemical abundances and physical conditions. The best approach to advance our understanding of these issues is to execute simultaneous UV/X-ray observations of the brightest AGN outflows, which are found in local Seyfert 1 galaxies. Here we report preliminary results from a deep simultaneous FUSE/HST/Chandra campaign on the Mrk 279 outflow. Unprecedented combination of high S/N data and unblended outflow troughs allows us to overcome the major obstacle in analyzing AGN outflow: the velocity-dependent non-black saturation. With this phenomenon accounted for we are able to advance towards a reliable determination of chemical abundances in the AGN environment. In addition we show the powerful diagnostics offered by multi epoch observations of the outflow troughs.
