Radio Jets Clearing the Way Through a Galaxy: Watching Feedback in Action in the Seyfert Galaxy IC 5063

High-resolution (0.5 arcsec) CO(2-1) observations performed with the At-acama Large Millimetre/submillimetre Array have been used to trace the kinematics of the molecular gas in the Seyfert 2 galaxyIC 5063. Although one of the most radio-loud Seyfert galaxy, IC 5063 is a relatively weak radio source (P-1.4 GHz = 3 x 10(23) W Hz(-1) The data reveal that the kinematics of the gas is very complex. A fast outflow of molecular gas extends along the entire radio jet (similar to 1 kpc), with the highest outflow velocities about 0.5 kpc from the nucleus, at the location of the brighter hot-spot in the W lobe. All the observed characteristics can be described by a scenario of a radio plasma jet expanding into a clumpy medium, interacting directly with the clouds and inflating a cocoon that drives a lateral outflow into the interstellar medium. This suggests that most of the observed cold molecular outflow is due to fast cooling of the gas after the passage of a shock and that it is the end product of the cooling process.
