THE EFFECTS OF DARK MATTER ANNIHILATION ON COSMIC REIONIZATION
We revisit the possibility of constraining the properties of dark matter (DM) by studying the epoch of cosmic reionization. Previous studies have shown that DM annihilation was unlikely to have provided a large fraction of the photons which ionized the universe, but instead played a subdominant role relative to stars …
