Abstract: Baryonic processes such as gas cooling, star formation and feedback has been shown to significantly alter the distributions of dark matter, for example, in dwarf galaxies. Hence properly constraining alternative theories of dark matter requires considering the effect of baryon physics. Here I will describe results of simulations of self-interacting dark matter and QCD axion dark matter, and their implication for galaxy structure and direct detection experiments.
