  We present an analysis of radio (Karl G. Jansky Very Large Array (VLA)),
optical (HST), and X-ray (Chandra and XMM-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 10 6
K, 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, being the first time this morphology is detected in a Herbig-Haro object
at these frequencies.
