Indirect Detection and Theoretical Models

Gamma-ray, cosmic-ray, and microwave observations all have the potential to reveal signals from annihilating or decaying WIMP dark matter. These astrophysical tests of dark matter are known as ``indirect detection,'' in contrast to the direct detection of WIMP-nucleon scattering in cryogenic detectors. I will review the latest measurements from PAMELA, FERMI, and other projects, and discuss the possibility that the observations could already contain signals from dark matter. I will then present a variety of theoretical models that are compatible with these observations, and propose criteria which must be fulfilled before a detection of dark matter can be claimed. Provocative statements will be made.
