Title: Feedback in Luminous Red Quasars at z~0.5

Abstract: The correlations between properties of supermassive black holes and stellar spheroids in galaxies imply a physical connection in spite of their vastly different masses and physical scales. Many quasar and galaxy evolution models postulate a spectacular ``blow-out'' phase, in which merger-driven accretion power succeeds in driving a powerful wind, clearing out the galaxy of future fuel for star formation. Red quasars, the most luminous quasars at every epoch, appear to be caught in this phase. Our previous Gemini programs have shown that luminous type 1 and type 2 radio-quiet quasars ubiquitously drive gas outflows similar to those by powerful radio galaxies. However, we miss a critical sample of red quasars that are likely in the postulated ``blow-out'' phase. We propose a GMOS IFU survey of the ionized gas nebulae in 10 non-radio- loud red quasars with WISE luminosities and redshifts matched to the observed type 2 sample. We will learn whether they also drive large- scale winds, and compare their morphology and energetics in the nebulosities to type 1 and 2 quasars. This program, along with our previous Gemini observations, will be a thorough investigation of the ionized gas outflows initiated by non-radio-loud supermassive black holes at z~0.5, and provide a solid point of comparison of the evolutionary state of different quasar populations.
