Data pubblicazione: | 2019 | Rivista: | ASTRONOMY & ASTROPHYSICS | Numero: | 626 | Da pagina:: | L3 | Abstract: | The [C II]λ158 μm line is one of the strongest far-infrared (FIR) lines and an important coolant in the interstellar medium of galaxies that is accessible out to high redshifts. 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. | URI: | http://hdl.handle.net/20.500.12386/29265 | URL: | https://www.aanda.org/articles/aa/abs/2019/06/aa35577-19/aa35577-19.html | ISSN: | 0004-6361 | DOI: | 10.1051/0004-6361/201935577 | Bibcode ADS: | 2019A&A...626L...3S | Fulltext: | open |
