We combine 158 hours of Segue 1 observations with MAGIC with 6-year observations of 15 dwarf satellite galaxies by the Fermi-LAT. We obtain limits on the annihilation cross-section for dark matter particle masses between 10 GeV and 100 TeV – the widest mass range ever explored by a single gamma-ray analysis. These limits improve on previously published Fermi-LAT and MAGIC results by up to a factor of two at certain masses. Our new inclusive analysis approach is completely generic and can be used to perform a global, sensitivity-optimized dark matter search by combining data from present and future gamma-ray and neutrino detectors.engjournal articlehttp://dx.doi.org/10.1088/1475-7516/2016/02/039http://iopscience.iop.org/open access537539.1Gamma-ray emissionLarge-area telescopeSpheroidal galaxiesMajor upgradeSearchConstraintsDecayHess.ElectricidadElectrónica (Física)Física nuclear2202.03 Electricidad2207 Física Atómica y Nuclear
