Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc

It is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M _⊙ . The distance is measured using surface br...
