MUSE reveals extended circumnuclear outflows in the Seyfert 1 NGC 7469

Astrophysics of Galaxies 2021-01-20 v1

Abstract

NGC 7469 is a well known Luminous IR Galaxy, with a circumnuclear star formation ring (830\sim 830 pc radius) surrounding a Seyfert 1 AGN. Nuclear unresolved winds were previously detected in X-rays and UV, as well as an extended biconical outflow in IR coronal lines. We search for extended outflows by measuring the kinematics of the Hβ\mathrm{H\beta} and [O III] λ5007\lambda 5007 optical emission lines, in data of the VLT/MUSE integral field spectrograph. We find evidence of two outflow kinematic regimes: one slower regime extending across most of the star formation ring -- possibly driven by the massive star formation -- and a faster regime (with a maximum velocity of 715 km s1-715 \ \mathrm{km \ s^{-1}}), only observed in [O III], in the western region between the AGN and the massive star forming regions of the ring, likely AGN-driven. This work shows a case where combined AGN/star-formation feedback can be effectively spatially-resolved, opening up a promising path toward a deeper understanding of feedback processes in the central kiloparsec of AGN.
