"The Multi-wavelength View of the Gamma-ray Sky"

The gamma-ray sky observed by the Energetic Gamma-ray Experiment Telescope (EGRET) encodes
much information about the high-energy processes in the universe. Of the EGRET resolved
sources, blazars comprise the class of gamma-ray emitters with the largest number of
identified members. Unresolved blazars are expected to contribute significantly to the
diffuse extragalactic gamma-ray emission. However, blazars are also broadband emitters
(from radio to TeV energies), and as such the multi-wavelength study of blazars can provide
insight into the high-energy processes of the universe.
