A 210 Megaparsec Ionized Structure at $z=6.8$ Revealed by an Astrophysics Foundation Model
Reionization is the last major transition in the Universe that transforms the intergalactic medium (IGM) from neutral to highly ionized, yet its spatial structure remains poorly constrained. Using an astrophysics foundation model trained for James Webb Space Telescope datasets, we identify a luminous galaxy at redshift...
