Regina Caputo (University of California, Santa Cruz)8/5/16, 5:00 PMAstro-particle Physics and CosmologyOral PresentationThe era of precision cosmology has revealed that ~80% of the total amount of matter in the universe is dark matter. One promising candidate, motivated by both particle physics and astrophysics, is the Weakly Interacting Massive Particle (WIMP). WIMPs are predicted to produce gamma rays via annihilation or decay which are detectable by the Fermi Large Area Telescope (Fermi-LAT). Indirect...Go to contribution page

Alex Drlica-Wagner (Fermilab)8/5/16, 5:20 PMAstro-particle Physics and CosmologyOral PresentationThe population of Milky Way satellite galaxies includes the least luminous, least chemically evolved, and most dark matter dominated galaxies in the known universe. Due to their proximity, high dark matter content, and lack of astrophysical backgrounds, dwarf spheroidal galaxies are promising targets for the indirect detection of dark matter via gamma rays. Prior to 2015, roughly two dozen...Go to contribution page

Benjamin Zitzer8/5/16, 5:40 PMAstro-particle Physics and CosmologyOral PresentationIn the cosmological paradigm, cold dark matter (DM) dominates the mass content of the Universe and is present at every scale. Candidates for DM include many extensions of the standard model with weakly interacting massive particles (WIMPs) in the mass range from ~10 GeV to greater than 10 TeV. The self-annihilation or decay of WIMPs in astrophysical regions of high DM density can produce...Go to contribution page

Aoife Bharucha (Université d'Aix-Marseille)8/5/16, 6:00 PMAstro-particle Physics and CosmologyOral PresentationThe relic density of TeV-scale wino-like neutralino dark matter in the MSSM is subject to potentially large corrections as a result of the Sommerfeld effect. A recently developed framework enables us to calculate the Sommerfeld-enhanced relic density in general MSSM scenarios, properly treating mixed states and multiple co-annihilating channels as well as including...Go to contribution page

Dr Bjorn Herrmann (Unite Reseaux du CNRS (FR))8/5/16, 6:15 PMAstro-particle Physics and CosmologyOral PresentationCalculating the neutralino relic density is a strong possibility to identify favoured and disfavoured regions of the parameter space of a supersymmetric theory such as the MSSM. With the latest results of the Planck mission, the cosmological parameters including the dark matter abundance are determined to an unprecedented precision. In order to reduce the theoretical uncertainty in the...Go to contribution page

William Shepherd (University of Copenhagen)8/5/16, 6:30 PMAstro-particle Physics and CosmologyOral PresentationI will present fully relativistic calculations of dark matter bound state wave functions and cosmological rates that result from realistic models of dark matter. These bound states can have significant impact on early-universe cosmology, and significantly influence the dark matter relic density. Relativistic effects on the bound state wavefunctions give important corrections in regions where...Go to contribution page
