Special Seminar

I will present a summary of current prospects for constraining dark matter models in high-redshift astronomy and discuss new avenues of investigation (and work in progress), including a self-consistent treatment of dark matter particle physics in cosmological simulations. Dark matter annihilation or decay in the era of galaxy formation has the potential to alter the evolution of early structures and the intergalactic medium, which may be detectable in the high-redshift 21cm signal of neutral hydrogen. I will discuss how feedback effects between different regimes of dark matter energy injection can alter the formation and evolution of the first stars and galaxies in previously unexplored ways.
