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.

First UVLF-based constraints on model-agnostic isocurvature power spectra for CDM, baryon, neutrino, and dark radiation modes yield consistent 95% credible envelopes over k ~ 0.5-10 Mpc^{-1}.
JWST UV luminosity function calibration of reionization history bounds primordial magnetic fields to √<B²> < 0.27 nG (n_B=-2) and < 0.18 nG (n_B=2) at 95% CL by ruling out double reionization at z≈24.
21 cm reionization topology breaks the degeneracy between self-interacting dark matter and astrophysical parameters that limits UV luminosity function constraints, enabling robust SIDM limits of σ/m ≳ 1-2 cm²/g independent of star formation models.
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.
A source 660 million years after the Big Bang is interpreted as a black hole star with a dust-free dense gas atmosphere, implying Little Red Dots have black hole masses overestimated by orders of magnitude.
Application of the Attenuation-Free Model to JWST super-early galaxies yields massive halos with moderate efficiencies and supports an evolutionary sequence from dust-reddened to UV-clear phases driven by outflows.
Cosmic star formation history provides complementary constraints on cosmological parameters, breaking degeneracies when combined with standard probes and yielding H0 = 68.28 ± 0.18 km s^{-1} Mpc^{-1} with DESI data.
An evolving star formation efficiency f_*(z) = 10^{0.13z-3.5} plus SNII-driven dust processes explain the UV LF at z=5-13, with galaxies retaining ~0.15% dust-to-stellar mass at z>9 and ALMA z=5-7 observations not representing the average population.

Hitting the slopes: A spectroscopic view of UV continuum slopes of galaxies reveals a reddening at z > 9.5
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.

Exploring the interplay between star formation efficiency and dust in regulating the UV luminosity of early systems in the JWST and ALMA era
An evolving star formation efficiency f_*(z) = 10^{0.13z-3.5} plus SNII-driven dust processes explain the UV LF at z=5-13, with galaxies retaining ~0.15% dust-to-stellar mass at z>9 and ALMA z=5-7 observations not representing the average population.
