Scientific paper

Excesses of Galactic gamma rays in the 1-100 GeV region observed by EGRET and
by WMAP have been interpreted as signals of dark matter (LSP) annihilation. We
argue that the excess of TeV gamma rays from the Galactic center observed by
H.E.S.S. signals a heavier dark matter component with a very small relic
density.
