Observation of Radio Galaxies and Clusters of Galaxies with VERITAS

Understand

Radio galaxies are the only non-blazar extragalactic objects detected in the VHE (E >100 GeV) band.

• These objects enable the investigation of the main substructures of the AGN, in particular the core, the jet and its interaction with the intergalactic environment.
• Clusters of galaxies, instead, have not been detected by gamma-ray observatories.
• These objects are collections of up to thousands of galaxies and are the densest large-scale structures in the universe.
