Description
Stochastic Fermi-type particle acceleration has emerged as a compelling mechanism for the efficient energization of particles in supermassive black hole systems. I will discuss recent advances, and exemplarily highlight: (i) the role of shear acceleration in sustaining ultra-relativistic electrons and protons in large-scale jets such as in Centaurus A, (ii) its implications for the production of extended (semi-steady) VHE emission in M87, and (iii) the efficiency of turbulent CR acceleration processes in neutrino-candidate Seyfert galaxies.
