Has JWST Already Falsified Dark-matter-driven Galaxy Formation?

Abstract The James Webb Space Telescope (JWST) discovered several luminous high-redshift galaxy candidates with stellar masses of M * ≳ 10 9 M ⊙ at photometric redshifts z phot ≳ 10, which allows to constrain galaxy and structure formation models. For example, Adams et al. identified the candidate ID 1514 with log 10 ( M * / M ⊙ ) = 9.8 − 0.2 + 0.2 located at z phot = 9.85 − 0.12 + 0.18 and Naidu et al. found even more distant candidates labeled as GL-z11 and GL-z13 with log 10 ( M * / M ⊙ ) = 9.4 − 0.3 + 0.3 at z phot = 10.9 − 0.4 + 0.5 and log 10 ( M * / M ⊙ ) = 9.0 − 0.4 + 0.3 at <jats:inline-for
