Paper Day! arxiv.org/abs/2506.15785; “How invisible stellar halos bias our understanding of ultra-faint galaxies”
In Wheeler+2019, we speculated that observed UFDs might be the bright central cores of more extended objects, and that they may have invisible stellar halos. (1/5)

How invisible stellar halos bias our understanding of ultra-faint galaxies
We explore how a realistic surface brightness detection limit of $μ_V \approx 32.5$ mag arcsec$^{-2}$ for stars at the edges of ultra-faint galaxies affects our ability to infer their underlying prope...
