Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST (2024)
Journal Article
Conroy, C., Johnson, B. D., van Dokkum, P., Deason, A., Tacchella, S., Belli, S., …Emami, R. (2024). Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST. The Astrophysical Journal, 968(2), Article 129. https://doi.org/10.3847/1538-4357/ad414a

We report the serendipitous discovery of an extended stellar halo surrounding the low-mass galaxy Ark 227 (M * = 5 × 109 M ⊙; d = 35 Mpc) in deep JWST NIRCam imaging from the Blue Jay Survey. The F200W–F444W color provides robust star–galaxy separati... Read More about Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST.
