Radio Galaxies

A thorough analysis of the population of radio galaxies indicates that they dominate the isotropic gamma-ray flux, this has implications for IceCube.

Star-Forming Galaxies

The contribution of star-forming galaxies to the isotropic gamma-ray flux is also large. This leads to an interesting source of tension, as the best-fit models for radio and star-forming galaxies combine to overproduce the total emission.
