Fermi 2nd-order + 1st-order DSA: power-law spectrum from diffusion-advection FP

Layer 1 — Physicsin the astroparticle-physics subtree

Fermi diffusive-shock-acceleration (DSA) framework — the canonical astrophysical mechanism for producing non-thermal power-law particle spectra at collisionless shocks (Fermi, Phys. Rev. 75, 1169, 1949; Krymskii 1977; Axford, Leer &…
