Take home messages Density is a crucial parameters to characterise outflows Observed outflow efficiencies are far from the 5 -10% required by classical models Compact radio sources can test if time is the main driver to explain the multiphase outflow properties More results from the rest of the sample Francesco Santoro - santoro@astro.rug.nl Malta - The role of gas in Galaxy Dynamics - Oct 2017
