Mapping the Temperature Profile of the AGN-driven Outflow in NGC1266
Abstract
An open question in the transition of galaxies from star-forming to quiescent is the role played by active galactic nuclei (AGN). NGC1266 provides an interesting window into this problem, as the post-starburst host of a massive molecular outflow driven by its AGN. We investigated the nature of the hot gas involved in this outflow, using Chandra observations of the extended X-ray emission in the vicinity of the AGN. We characterized the temperature profile of this gas both along the direction and perpendicular to the outflow and sought to find whether gradients in the temperature of the gas exist. We present the temperature maps of the hot gas that resulted from this analysis. Characterizing the properties of the hot component of the outflow of NGC1266 provides important insights into the role of AGN feedback in the transition to quiescence. This in turn will aid in the interpretation of other local post-starburst galaxies including NGC1377 and IC860.
