Dark Matter search with H.E.S.S. towards ultra-faint dwarf nearby DES satellites of the Milky Way

Understand

Several nearby ultra-faint satellites of the Milky Way discovered by the Dark Energy Survey (DES) during the last few years are promising targets for indirect dark matter (DM) searches with very-high-energy (VHE, E$\gtrsim$100 GeV) gamma rays.

• The H.E.S.S.
• experiment has carried out an observational campaign in 2017 and 2018 towards a selection of the most promising DES dwarf satellites, accumulating a total observation time of about 80 hours.
• The individual datasets have been used to look for a DM signal in several annihilation channels.
