Particle acceleration and magnetic field amplification in the jets of 4C74.26
Astrophysical Journal American Astronomical Society 806:2 (2015) ARTN 243
Abstract:
We model the multi-wavelength emission in the southern hotspot of the radio quasar 4C74.26. The synchrotron radio emission is resolved near the shock with the MERLIN radio-interferometer, and the rapid decay of this emission behind the shock is interpreted as the decay of the amplified downstream magnetic field as expected for small scale turbulence. Electrons are accelerated to only 0.3 TeV, consistent with a diffusion coefficient many orders of magnitude greater than in the Bohm regime. If the same diffusion coefficient applies to the protons, their maximum energy is only ~100 TeV.Particle acceleration and magnetic field amplification in the jets of 4C74.26
