The science working group discusses the science potential of a future ground based gamma-ray experiment in the field of extragalactic gamma-ray astrophysics. Gamma-ray observations of extragalactic objects allow us to address the following science topics: (i) the environment and growth of Supermassive Black Holes; (ii) the acceleration of cosmic rays in other galaxies; (iii) the largest particle accelerators in the Universe, including radio galaxies, galaxy clusters, and large scale structure formation shocks; (iv) study of the integrated electromagnetic luminosity of the Universe and intergalactic magnetic field strengths through processes including pair creation of TeV gamma-rays interacting with infrared photons from the Extragalactic Background Light.
