Abstract
The first few 100 Myr at z> 10 mark the last major uncharted epoch in the history of the universe, where only a single galaxy (GN-z11 at z≈ 11) is currently spectroscopically confirmed. Here we present a search for luminous z> 10 galaxies with JWST/NIRCam photometry spanning≈ 1–5 μm and covering 49 arcmin 2 from the public JWST Early Release Science programs (CEERS and GLASS). Our most secure candidates are two M UV≈− 21 systems: GLASS-z12 and GLASS-z10. These galaxies display abrupt≳ 1.8 mag breaks in their spectral energy distributions (SEDs), consistent with complete absorption of flux bluewards of Lyα that is redshifted to
