We present an analysis of radio (Karl G. Jansky Very Large Array (VLA)), optical (Hubble Space Telescope(HST)), and X-ray (ChandraandXMM–Newton) observations and archival data of the Herbig–Haro objects HH 80 and HH 81 in the context of jet–cloud interactions. Our radio images are the highest angular resolution to date of these objects, allowing to spatially resolve the knots and compare the regions emitting in the different spectral ranges. We found that soft X-ray thermal emission is located ahead of the non-thermal radio peak. This result is consistent with a radiative forward shock that heats the shocked gas up to 106K, and an adiabatic reverse shock able to accelerate particles and produce synchrotron radiation detectable at radio frequencies. These high angular resolution radio images also reveal a bow shock structure in the case of HH 80N, with it being the first time this morphology is detected in a Herbig–Haro object at these frequencies.
