Title: Mapping sub-kpc gas flows in NGC1365

Abstract: We propose GMOS IFU emission-line spectroscopy of the gas within the inner kiloparsec of the nearby activity galaxy NGC1365. This is part of a program of optical and NIR IFU spectroscopy to map the kinematics and excitation conditions of the circum-nuclear gas in a sample of 20 nearby active galaxies. Our main goal is to study AGN "feeding" and "feedback" processes on sub-kiloparsec scales for range of activity types and luminosities. As a barred spiral with a Seyfert Type 1.9 nucleus and a high ionization outflow, NGC1365 represents a prime opportunity to study the links between large scale motions along the bar, AGN fuelling, and AGN-driven outflow. The proposed observations will map the kinematics and ionization structure of the circumnclear gas on scales 50 pc. We will use the [OIII] emission lines to map the outflowing gas and Halpha emission to look for inflows associated with the dust lanes extending inwards from the large scale bar. We will estimate mass inflow and outflow rates from the data and for the sample as a whole, relate these to the current inferred AGN accretion rates.
