Title: What's the (dark) matter with dwarf galaxies?

Abstract: Dwarf galaxies provide a very important and intriguing laboratory for the study of both dark matter and galaxy formation physics. I will present results from extremely high resolution, fully cosmological simulations that contain many isolated dwarf galaxies as well as satellite dwarf galaxies . Together, they create the largest collection of high-resolution simulated dwarf galaxies to date and the first collection to resolve ultra-faint dwarf galaxies in multiple environments. With this flagship suite I can statistically characterize dwarf galaxies in order to constrain both baryonic and dark matter physics. I will answer the following key question: What testable predictions can we make to constrain dark matter, star formation and feedback with dwarf masses? Finally,this talk will also highlight preliminary results of dwarf galaxy simulations with self-interacting dark matter (SIDM), in which dark matter interacts only with itself non-gravitationally through e.g. a Yukawa interaction.
