Object

NGC6240

Abstract

We propose Resolve measurements of Fe K lines in to determine whether the starburst wind in NGC 6240 can drive a quenching outflow. NGC 6240 is the archetypal major merger, with a starburst, two AGN, and a molecular outflow of around 4000 solar masses per year coincident with the starburst that will rapidly quench the galaxy. If the starburst cannot drive the wind, then the AGN must. These data will also enable the kinematic separation of the dual AGN in Fe Ka, making NGC 6240 (where these nuclei are resolved by Chandra) a Rosetta stone for interpreting kinematic signatures of candidate dual or binary AGN in more distant systems. Finally, high-resolution spectra from the starburst wind will also constrain the metal outflow rate, key to measuring the cumulative enrichment of the cosmic web.
