Dark matter remains invisible, but could be betrayed by energy-rich gamma rays. An evaluation of 546 observation hours of the H.E.S.S. telescope system finds no corresponding signal, but sets the narrowest limits for heavy particle candidates to date. Under a widespread assumption for the distribution of matter in the Milky Way, the search reaches for the first time the area expected for thermal Higgsinos. Heidelberg (Germany). Dark matter makes…
