Gemini AI Agent Identifies 13.4 Billion-Year-Old Galaxy Candidate in JWST Data

Lyman-break galaxyLyman-break galaxies are star-forming galaxies at high redshift that are selected using the differing appearance of the galaxy in several imaging filters due to the position of the Lyman limit. The technique has primarily been used to select galaxies at redshifts of z = 3–4 using ultraviolet and optical filters, but progress in ultraviolet astronomy and in infrared astronomy has allowed the use of this technique at lower[1] and higher redshifts using ultraviolet and near-infrared filters.3h agoWikipedia

@fofrAI The brown dwarf rejection step is the part that actually impresses me. That's usually where human astronomers spend the most time arguing over SED fits, and false positives from cool dwarfs are the classic trap in high z dropout searches.
