Description
The discovery of diffuse optical and X-ray synchrotron emission in a number of low-power radio hotspot requires a revision of the standard scenario of particles accelerated by a single strong shock generated at the jet termination. High energy electrons like those responsible for the X-ray emission should arise from very small regions because their short lifetime should limit their emission to a narrow emitting disk. We present the results of our multi-wavelength campaign on a small sample of hot spots of the 3C catalogue. The high-sensitivity JVLA, near-infrared and optical observations allowed us to probe the small-scale structure of the hot spots, unveiling the presence of compact (
