Direct detection of ionizing photons from z~6 faint galaxies yields escape fraction ~0.8 and log ξ_ion^true = 25.86, implying higher IGM transparency and that young low-metallicity stars in such galaxies can reionize the universe.
A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
The UV luminosity function at z~7 rises steeply with slope alpha=-1.98 to M_UV=-12.3 with no turnover, indicating faint galaxies dominate the ionizing photon budget during reionization.
A massive galaxy at z=9.3 shows bursty star formation with a recent downturn and sits in a small ionized bubble in a neutral IGM.
New JWST pure-parallel imaging over 400 arcmin² yields UV luminosity functions at z~7.5-10 consistent with pre-JWST models and significant clustering of bright galaxies implying they occupy more massive halos than previously modeled.
COLIBRE simulations underpredict bright-end UV galaxy luminosities by 1 to 2.5 magnitudes at z=7-15 compared with observations, with the discrepancy persisting after dust attenuation and uncertainty accounting.
Lambda CDM with the UniverseMachine model on the Uchuu simulation matches JWST/HST UV observations at z=7-14 and predicts star formation efficiency rising to 2-3% by z=10-12.
JADES DR5 delivers 2081 z_phot > 8 galaxy candidates with UV slope trends, morphological evidence of clumpy growth, and improved photo-z methods tested on a spectroscopic subsample.
Simulations of high-redshift galaxies show the 1719 Å UV index reliably traces stellar metallicity while others are more sensitive to star formation history.
Small-scale power spectrum boosts alter ionization morphology enough that 21 cm power spectra and bubble sizes remain distinguishable from Lambda CDM under current constraints, offering SKA a probe for such deviations.
