JWST spectroscopy of 295 galaxies at 5.5 < z < 14.3 shows UV slope beta reddening at z > 9.5, with lack of dust as the main driver of bluer values and nebular continuum at T > 15,000 K able to reproduce the observed range without dust.

The low-mass IMF in Boötes I is consistent with the Milky Way within 68% confidence for broken power-law and lognormal forms, indicating universality at low metallicity.
Lyα radiation pressure mildly reduces gas-to-star conversion efficiency in dense high-redshift clusters while dominating the launch of rapid outflows.
A transition to low-opacity SNe-produced dust at z>9 reproduces the observed low attenuation and UV luminosity function excess in early galaxies.
High-redshift HeII emitter observations confirm a >50% PopIII stellar mass fraction and favor top-heavy IMFs for the first stars with total masses 2e4 to 6e5 solar masses.
A pair-instability supernova from a 250-260 solar mass Population III star at z≈15 matches the brightness, variability, photometry, and spectrum of the JWST source Capotauro.
Lumina runs a 500 cMpc radiation-hydrodynamic simulation combining IllustrisTNG galaxy formation with six-bin M1 radiation transport to predict late stellar-driven HI reionization ending around z=4.75 and AGN-driven HeII reionization nearly complete by z=3.
Semi-numerical simulations plus Fisher analysis show that REACH-like observations of the 21-cm global signal can place meaningful constraints on the mass and star-formation efficiency of Population III stars.
The PFS Galactic Archaeology survey will observe thousands of stars in Local Group systems to measure density profiles in dwarfs and compare assembly histories of M31 and the Milky Way.
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.
Intermediate-mass black holes acting as permanent matter sinks, combined with updated cosmic star formation rates and primordial baryon accretion, reduce the overpredicted CNO abundances from Population III stars to match observations in z~3-6 quasar absorption systems.
