Description
We consider the boosted dark matter(BDM) model that consists of two-component dark matter with the boost effect from the annihilation of heavier DM into lighter one and the self-heating effect from the self-interaction of lighter DM. These effects suppress the formation of small-scale structures, and this suppression affects 21cm signal. We expect that BDM model will change 21cm signal and reionization history, and that these change may detectable in Square Kilometer Array (SKA), a future 21cm hydrogen line observatory.
