DESCRIPTION:Cosmological probes of the early Universe offer a powerful way
  to test dark matter scenarios that modify its thermal and ionization hist
 ory. The cosmic microwave background already places some of the strongest 
 constraints on models involving exotic energy injection\, while upcoming 2
 1-cm observations promise a new window into the cosmic dawn and the epoch 
 of reionization. These measurements are also sensitive to the uncertain pr
 operties of the first stars and galaxies\, making the interpretation of da
 rk matter signatures especially challenging.\n\nIn this talk\, I will revi
 ew current cosmic microwave background constraints on annihilating dark ma
 tter and primordial black holes\, and then discuss how astrophysical uncer
 tainties impact forecast constraints from the 21-cm signal.\n\nhttps://ind
