Title: Feedback in action: mapping the molecular outflow in NGC1266 with NIFS+LGS-AO

Abstract: NGC1266 is an ordinary-looking early-type galaxy harboring an extra-ordinary amount of dense molecular gas, a significant fraction of which is leaving the galaxy centre in a massive, compact outflow. X-ray and radio data reveal the presence of an AGN, which is likely responsible for powering the outflow given the insufficient energy from ongoing star formation. This appears to be a 'text-book' case of AGN-driven feedback resulting in a 'quenching' of the star formation, which in turn may be responsible for driving this galaxy to join the red sequence. We propose to put this speculation to the observational test by obtaining high spatial resolution observations of the stellar, gas and dust properties of NGC1266 using NIFS with LGS-AO. By mapping the central dynamics (stars and gas), star-formation history and emission line distributions at HST-like resolution, we will attempt to directly determine the causal connections between the accreting central black hole, the molecular outflow, and the star formation properties (both past and present). In addition, we will obtain an accurate dynamical measure of the central black hole mass, and search for dynamical and chemical tracers of the events that lead up to this brief but crucial phase of this galaxy's evolution.
