How Invisible Stellar Halos Bias Our Understanding of Ultrafaint Galaxies
We explore how a realistic surface brightness (SB) detection limit of μ _V ≈ 32.5 mag arcsec ^−2 for stars at the edges of ultrafaint galaxies affects our ability to infer their underlying properties. We use a sample of 19 galaxies with stellar masses ≈400–40,000 M _⊙ simulated with FIRE-2 physics a...
