The maturation of very high energy astrophysics has enabled many novel physics applications. Among these is the investigation of extragalactic photon fields, which in some cases encode specific calorimetric information about such things as the formation of large-scale structure and the total high-energy luminosity of the universe. The origins of these backgrounds, and techniques for probing them will be discussed. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
