To appreciate that some galaxies emit far more energy at some wavelengths that can be explained simply in terms of ‘starlight’.. To recall the types of active galaxies.. To show an understanding of the mechanism for producing large quantities of radiation from active galaxies.. Can we see statistical evidence for the influence of external (AGN) photons in . blazar.

Quasars and blazars. A quasar is an active galactic nucleus with a supermassive black hole as the center.. It is thought to be formed by the collision of two galaxies.. A blazar is a more compact and energetic quasar, with the jet pointing towards the Earth.. Will Potter. Junior Research Fellow, . University of Oxford. Outline.
