“The Prospects for Indirect Detection of Dark Matter - Analysis of the WMAP Haze”

There is currently a significant effort to indirectly detect dark matter through the observation of stable products of dark matter annihilation. Cutting edge observations have allowed us to inspect the expected dark matter signal from both massive particles and photon energies spanning 16 orders of magnitude. However, the current results have been inconclusive, and sometimes contradictory. One interesting result was an unexpected synchrotron haze (the øWMAP hazeø), with a similar intensity and morphology to those predicted by theoretically motivated dark matter models. We evaluate a wide variety of well motivated dark matter particle physics setups as well as cosmic ray propagation models, and compare the simulated dark matter driven synchrotron signal against the observed WMAP haze. Further analyzing several reasonable dark matter fits to the WMAP haze, we determine the expected inverse-Compton scattering and positron/electron signals which should be detectable by cutting-edge Fermi and Pamela observations. Finally, we will investigate the role that astrophysical uncertainties play in our attempts to detect a resilient dark matter signal.
