A promising way to identify the nature of dark matter (DM) and to measure its properties is to search for the Standard Model particles produced through annihilation or decay at DM over-densities in the local Universe. Current gamma-ray instruments like the Fermi-LAT in space or the ground-based MAGIC telescopes are sensitive to overlapping and complementary DM masses. These instruments have dedicated programs to look for DM signals coming from e.g. the Galactic center and halo, galaxy clusters or dwarf satellite galaxies. In this pizza seminar I present the first joint MAGIC/Fermi-LAT DM search for annihilation signals in dwarf galaxies. We have searched for a DM particle of mass between 10 GeV and 100 TeV. We obtain limits that improve on previously published Fermi-LAT and MAGIC results by up to a factor of two at certain masses. This 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.
