Hydrodynamical simulations predict that the jets of young radio sources caninhibit star formation in their host galaxies by injecting heat and turbulenceinto the interstellar medium (ISM). To investigate jet-ISM interactions in agalaxy with a young radio source, we have carried out a multi-wavelength studyof the $z = 0.025$ Compact Steep Spectrum radio source hosted by the early-typegalaxy UGC 05771. Using Keck/OSIRIS observations, we detectedH\textsubscript{2} 1--0 S(1) and [Fe \textsc{ii}] emission at radii of 100s ofpc, which traces shocked molecular and ionised gas being accelerated outwardsby the jets to low velocities, creating a `stalling wind'. At kpc radii, wedetected shocked ionised gas using observations from the CALIFA survey,covering an area much larger than the pc-scale radio source. We found thatexisting interferometric radio observations fail to recover a large fraction ofthe source's total flux, indicating the likely existence of jet plasma on kpcscales, which is consistent with the extent of shocked gas in the host galaxy.To investigate the star formation efficiency in UGC 05771, we obtained IRAM COobservations to analyse the molecular gas properties. We found that UGC 05771sits below the Kennicutt-Schmidt relation, although we were unable todefinitively conclude if direct interactions from the jets are inhibiting starformation. This result shows that jets may be important in regulating starformation in the host galaxies of compact radio sources.
