Title: What is driving quasar winds in radio-quiet luminous AGN?

Abstract: In powerful radio galaxies relativistic jets can interact with the interstellar medium of the host galaxy, producing cocoons and carrying material out of the galaxy. But what is driving quasar feedback activity in radio-quiet quasars? Is it accomplished through the mechanical action of jets or through nuclear winds driven by radiation pressure? In this proposal we will investigate a sample of 10 quasars with the strongest ionized gas outflows to definitively answer the questions of what drives gas outflows in radio-quiet quasars. We propose a GMOS integral field unit survey of 10 luminous quasars at z=0.2-0.7. We will obtain resolved [OIII] kinematics of the ionized gas and combine these data with high resolution radio images we are simultaneously obtaining with the EVLA. We will measure outflow energetics, ouflow direction and spatial extents of the ionized gas nebulae. In combination with the EVLA radio data, these observations will go to the heart of one of the key issues in modern galaxy formation of whether quasar feedback is ultimately driven by collimated outflows or by disk winds.
