The excitation of [C II] is complex and can best be studied in detail at low redshifts. Here we report the discovery of the highest global [C II] excess with respect to the FIR luminosity in the nearby AGN host galaxy HE 1353-1917. This galaxy is exceptional among a sample of five targets because the AGN ionization cone and radio jet directly intercept the cold galactic disk. As a consequence, a massive multiphase gas outflow on kiloparsec scales is embedded in an extended narrow-line region. Because HE 1353-1917 is distinguished by these special properties from our four bright AGN, we propose that a global [C II] excess in AGN host galaxies could be a direct signature of a multiphase AGN-driven outflow with a high mass-loading factor.STAMPAenArticle10.1051/0004-6361/2019355772-s2.0-85082833842000471640400001https://www.aanda.org/articles/aa/abs/2019/06/aa35577-19/aa35577-19.html2019A&A...626L...3SFIS/05 - ASTRONOMIA E ASTROFISICA
