Abstract
Several lines of argument support the existence of a link between activity at the nuclei of galaxies, in the form of an accreting supermassive black hole, and star-formation activity in these galaxies. The exact nature of this link is still under debate. Radio jets have long been argued to be an ideal mechanism that allows AGN to interact with their host galaxy, either by depositing energy in the inter-stellar medium (ISM) and effectively suppressing or even quenching star-formation, or by driving shocks through the ISM, compressing molecular gas, and setting the stage for triggering star
