By observing the local luminous infrared galaxy NGC5135 with the near-IR IFUspectrograph SINFONI (ESO-VLT), we report an approx. 600 pc (in projection) AGNoutflow traced by [SiVI]1.96mum emission. This is the largest outflow traced bya coronal line ever reported. Its large spatial scale suggests that shocks, inaddition to AGN continuum emission, are needed to locally produce [SiVI]emission. We also show, for the first time, clear kinematical evidence of theAGN-outflow vs. ISM interaction through variations in the 2D velocity fields ofdifferent gas phases. Such local perturbations in the kinematics clearly matchthe outflow structure. We use the [FeII]1.64mum emission, a supernovae tracer,to estimate the supernovae rate in different star-forming knots (approx. 250 pcacross) within the central 2.3 kpc of NGC5135. The estimated supernovae ratesgo from 0.02 to 0.08 yr^{-1} being in excellent agreement with predictions from6 cm radio emission in the same areas.
