Query: Constraints on cross-section and lifetime of dark matter with HAWC
  Observations of dwarf Irregular galaxies   It has been shown that the dynamics of dwarf Irregular (dIrr) galaxies are
dominated by dark matter. It is also observed that these galaxies have low star
formation rates and metallicities, and no gamma-ray emission at ultra very high
energies is expected. Because of their distance, dark matter content and vast
number, dIrr galaxies are good targets to perform indirect dark matter searches
by ground-based and wide field of view gamma-ray experiments, like HAWC. We
analyzed data at the position of 31 dIrr galaxies within the HAWC field-of-view
and no significant excess was found. Here, we present the individual and
combined limits on the annihilation cross-section and decay lifetime of weakly
interacting massive particles with a mass between 1 and 100 TeV.
