Testable Predictions of Outside-in Age Gradients in Dwarf Galaxies of All Types
We use a sample of 73 simulated satellite and central dwarf galaxies spanning a stellar mass range of 10 ^5.3 –10 ^9.1 M _⊙ to investigate the origin of their stellar age gradients. We find that dwarf galaxies often form their stars “inside-out,” i.e., the stars form at successively larger radii ove...
