Abstract: The cosmological model based on cold dark matter (CDM) and dark energy has been hugely successful in describing the observed evolution and large scale structure of our Universe. However, at small scales (in the smallest galaxies and at the centers of larger galaxies), a number of observations seem to conflict with the predictions of CDM cosmology. These small scales, though, are also regions dominated by baryons (gas and stars). I will show results from high resolution cosmological galaxy simulations that include gas, stars, and dark matter to show that baryonic physics can significantly alter the dark matter structure and substructure of galaxies, possibly solving CDM's small scale problems.
