Abstract
The HESS observations of TeV emission from M87 proves challenging for traditional acceleration and emission models. We discuss a new pulsar-type scenario for the origin of variable VHE emission close to the central supermassive black hole, showing that centrifugally accelerated electrons can Compton upscatter sub-mm ADAF disk photons to the TeV regime with resultant characteristics close to the observed ones.
