Canonical high power blazars

Understand

The jets of powerful blazars propagate within regions relatively dense of radiation produced externally to the jet.

• This radiation is a key ingredient to understand the origin of the high energy emission of blazars, from the X-ray to the gamma-ray energy band.
• These external radiation fields control the amount of the inverse Compton radiation with respect to the synchrotron flux.
• Therefore the predicted spectral energy distribution (SED) will depend on where the jet dissipates part of its energy to produce the observed radiation.
