The sensitivity of these searches is improved by combining the observations of dSphs made by different gamma-ray telescopes. We present the results of a combined search by the most sensitive currently operating gamma-ray telescopes, namely: the satellite-borne Fermi-LAT telescope; the ground-based imaging atmospheric Cherenkov telescope arrays H.E.S.S., MAGIC, and VERITAS; and the HAWC water Cherenkov detector. Individual datasets were analyzed using a common statistical approach. Results were subsequently combined via a global joint likelihood analysis. We obtain constraints on the velocity-weighted cross section 〈σv〉 for DM self-annihilation as a function of the DM particle mass. This five-instrument combination allows the derivation of up to 2-3 times more constraining upper limits on 〈σv〉 than the individual results over a wide mass range spanning from 5 GeV to 100 TeV. Depending on the DM content modeling, the 95% confidence level observed limits reach 1.5×10−24 cm3s−1 and 3.2×10−25 cm3s−1, respectively, in the τ+τ− annihilation channel for a DM mass of 2 TeV.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal article1475-7516https://dx.doi.org/10.1088/1475-7516/2026/03/035https://iopscience.iop.org/article/10.1088/1475-7516/2026/03/035open access52-33Dark matter experimentsDwarfs galaxiesGamma ray experimentsAstrofísica21 Astronomía y Astrofísica
