Dissipative processes and their role in the evolution of radio galaxies
M Perucho - Galaxies, 2019 - mdpi.com
Particle acceleration in relativistic jets, to very high levels of energy, occurs at the expense of
the dissipation of magnetic or kinetic energy. Therefore, understanding the processes that …
