Abstract / Description:The detection of rapidly variable TeV emission on timescales of about one day in the nearby radio galaxy M87 implies a source size of a few Schwarzschild radii only. Recent radio imaging has shown that the TeV variability is accompanied by an increase in the radio flux very close to the core, providing further evidence that the required energetic charged particles are accelerated in the vicinity of the central black hole itself. Motivated by this, I will discuss magnetospheric models, where the relevant non-thermal processes are considered to occur at the base of a rotating black-hole-jet magnetoshere.
