  Dwarf Galaxies

  Dwarf galaxies are both the smallest and the most abundant galaxies, and are some of the best tests of our astrophysical and cosmological theories. My current interest lies in tying our simulated dwarf galaxies to current and future observations. Surveys like LSST will provide an unprecedented view of the nearby Universe, and theoretical simulations will be key in interpreting these results. In particular, I am interested in ultra-faint dwarf galaxies, which are galaxies with as few as several hundred or thousand stars.

  About the Simulations

  These simulations form and evolve realistic galaxies in large volumes. I study simulations run with the N-Body + SPH code ChaNGa, meaning the equations governing gravity and fluid dynamics are solved simultaneously.

  Star Formation

  What drives star formation in galaxies? Why do galaxies stop forming stars? How can we connect stellar populations in simulations to ones that we see in observations? I focus on answering these questions and more.

  ---

  Since simulation resolution is limited by computational resources, analytic prescriptions for star formation must be included. Recent work has focused on building physically motivated star formation and feedback schemes.
