“Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun.” - Douglas Adams

\[ \frac{T_{t,m}}{T_{t,e}} = (\frac{E_m}{E_e})^{1/4} (\frac{M_m}{M_e})^{-1/6} \]

Efficient Nonthermal Particle Acceleration

by the Kink Instability in Relativistic Jets

#journal club

Extragalactic jets from active galactic nuclei (AGNs) carry relativistic magnetized plasma and produce nonthermal electrons/positrons that radiate from radio to TeV energies.
