CTAO could set competitive limits on dark matter annihilation cross sections from dwarf irregular galaxies, reaching around 2×10^{-24} cm³/s for 100 GeV WIMPs in the tau channel and exceeding dwarf spheroidal expectations for velocity-dependent cases due to subhalos.

MINOT modeling of Abell 3667 predicts a hadronic 1–300 GeV flux of ~1.15e-10 cm^-2 s^-1 at 3.7 R500, matching Fermi-LAT, with ~76% of flux outside R500 and IC subdominant by ~20.
