Q1.00001: Dark Matter Observed in the Universe Invited Speaker: |

Q1.00002: Indirect Detection and Theoretical Models Invited Speaker: 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. [Preview Abstract] |

Q1.00003: Recent Results on Dark Matter Searches with Fermi Invited Speaker: The Fermi Large Area Telescope (LAT) has been successfully launched from Cape Canaveral on 11 June 2008. It is exploring the gamma ray sky in the energy range from 20 MeV to over 300 GeV with unprecedented sensitivity. One of the most exciting science questions that the Fermi LAT will address is the nature of dark matter. Several theoretical models have been proposed that predict the existence of Weakly Interacting Massive Particles (WIMPs) that are excellent dark matter candidates. The Fermi LAT investigates the existence of WIMPs indirectly, primarily through their annihilation or decay into photons and into electrons and positrons. I will present recent results on these searches. [Preview Abstract] |
