Summary>10σ EGRET excess shows thatWIMP is thermal relic with expected annihilation into quark pairsDM becomes visible by gamma rays from fragmentation(30-40 gamma rays of few GeV pro annihilation from π0 decays)Results rather model independent, since only KNOWN spectral shapes ofsignal and background used, NO model dependent calculations of abs.fluxes.Different models or unknown experimental problems may change boostfactor and/or WIMP mass, BUT NOT the distribution in the sky.SPATIAL DISTRIBUTION of annihilation signal is signature for DMAwhich clearly shows that EGRET excess is tracer of DM by fact thatone can CONSTRUCT ROTATION CURVE FROM GAMMA RAYS.DM interpretation strongly supported N-body simulation of CanisMajor dwarf and its tidal streams coinciding with the EGRET excessEGRET shows lots of DM mass in the tidal streams -> GAS FLARINGWim de Boer, Karlsruhe Seminar Oxford, May. 3, 2007 32
