My Google Scholar profile

Research interests - multifrequency activity of Active Galactic Nuclei, from radio frequencies up to very high energy gamma rays, radiative processes - especially synchrotron emission and inverse-Compton scattering, and also particle acceleration inside astrophysical jets.

A few examples of my work

Multifrequency emission of Mrk 501. A simple explanation of the high energy emission of TeV blazars. Rapid variability of PKS 2155-304. Do we really need to assume very fast blobs to explain such rapid variability?
