Abstract
The Seyfert 2 galaxy Markarian 78 offers a rare opportunity to study the interaction of kpc scale radio outflows with the surrounding emission line gas. Using VLA and HST imaging and spectroscopy we identify a number of signatures of the interaction, including jet disruption and deflection. Folding in kinematic features, we identify three regions which may be exhibiting early, intermediate, and late stages of cloud disruption by the jet flow. Emission line ratios do not uniquely favour either photo- or shock ionization, however the lack of correlations between line ratios and velocities argues against the importance of shock ionization.
