On the maximum energy of non-thermal particles in the primary hotspot of Cygnus A
Original language description
We study particle acceleration and magnetic field amplification in the primary hotspot in the north-west jet of radiogalaxy Cygnus A. By using the observed flux density at 43 GHz in a well-resolved region of this hotspot, we determine the minimum value of the jet density and constrain the magnitude of the magnetic field. We find that a jet with density greater than 5 x 10(-5) cm(-3) and hotspot magnetic field in the range 50-400 mu G are required to explain the synchrotron emission at 43 GHz.
