We present ultra-high resolution cosmological hydrodynamic simulations of M? ' 104−6M dwarf galaxies that form within Mvir = 109.5−10M dark matter halos. Our simulations rely on the FIRE implementation of star formation feedback and were run with high enough force and mass resolution to directly resolve stellar and dark matter structure on the∼ 200 pc scales of interest for classical and ultra-faint dwarfs in the Local Group. The resultant galaxies sit on the M? vs. Mvir relation required to… CONTINUE READING
