The infrared peak of the blazar spectral energy distribution and the monitoring from Antarctica
Blazars are a class of Active Galactic Nuclei (AGN) with a highly luminous and rapidly variable non-thermal emission. Their overall Spectral Energy Distribution (SED) is a smooth and featureless continuum with a typical two bump structure due to synchrotron and inverse Compton radiation. The energy...
