Zusammenfassung
Abridged We combine extensive spatially-resolved multi-wavelength
observations, taken as part of the Close AGN Reference Survey (CARS), for the
edge-on disc galaxy HE1353-1917 to characterize the impact of the AGN on its
host galaxy via outflows and radiation. Multi-color broad-band photometry is
combined with spatially-resolved optical, NIR and sub-mm and radio observations
taken with VLT/MUSE, Gemini-N/NIFS, ALMA and the VLA to map the physical
properties and kinematics of the multi-phase inter-stellar medium (ISM). We
detect a biconical extended narrow-line region (ENLR) ionized by the luminous
AGN oriented nearly parallel to the galaxy disc, extending out to at least
25kpc. The extra-planar gas originates from galactic fountains initiated by
star formation processes in the disc, rather than an AGN outflow, as shown by
the kinematics and the metallicity of the gas. Nevertheless, a fast multi-phase
AGN-driven outflow with speeds up to 1000km/s is detected close to the nucleus
at 1kpc distance. A radio jet, in connection with the AGN radiation field, is
likely responsible for driving the outflow as confirmed by the energetics and
the spatial alignment of the jet and multi-phase outflow. Evidence for negative
AGN feedback suppressing the star formation rate (SFR) is mild and restricted
to the central kpc. But while any SFR suppression must have happened recently,
the outflow has the potential to greatly impact the future evolution of the
galaxy disc due to its geometrical orientation. Our observations reveal that
low-power radio jets can play a major role in driving fast multi-phase
galaxy-scale outflows even in radio-quiet AGN. Since the outflow energetics for
HE1353-1917 are consistent with literature scaling relations of AGN-driven
outflows the contribution of radio jets as the driving mechanisms still needs
to be systematically explored.
