Small Statistics No More: A Suite of Dwarf Galaxy Simulations to Interpret Observations

Alyson Brooks, Associate Professor, Rutgers, the State University of New Jersey,

The past decade has seen tremendous progress in simulating realistic dwarf galaxies. Despite the hype, not all dwarfs are simulated equally. Given their shallow potential wells, dwarfs are an excellent probe of star formation and feedback processes. In this talk, I'll outline a campaign to simulate the largest suite of dwarf galaxies to date, in environments both near the Milky Way (the DC Justice League simulations) and further afield (the Marvel simulations). These high-resolution simulations are probing dwarf galaxy formation from LMC-mass scales down into the regime of the ultra-faints for the first time. Our realistic dwarf galaxies can be used to interpret galaxy formation and to make predictions for future observations. I will highlight some of the first results from the Marvel and Justice League suites of simulations.
