Self-annihilating dark matter and the CMB: reionizing the Universe and constraining cross sections
Self-annihilating dark matter and the CMB: reionizing the Universe and constraining cross sections
I summarize the recent advances in determining the effects of self-annihilating WIMP dark matter on the modification of the recombination history, at times earlier than the formation of astrophysical objects. Depending on mass and self-annihilation cross section, WIMP DM can reproduce sizable amounts of the total free electron abundance at …
