A new analytical formalism self-consistently predicts both the ionized fraction x_i(z) and photoionization rate Gamma_HI(z), achieving percent-level accuracy in x_i and 20-30% accuracy in Gamma_HI versus radiative transfer simulations at z less than or equal to 6.

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.
No monotonic reionization history fits Planck τ, patchy kSZ from SPT/ACT, and Lyα endpoint; an early ionization phase at z≳12 relaxes ∑mν<0.39 eV and shifts σ8 via As-τ degeneracy.
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.
Axion EDE model fitted to Planck/ACT/SPT CMB, DESI BAO, and JWST UV luminosity function data yields H0 = 71.58 ± 1.05 km s^{-1} Mpc^{-1}, reduces H0 tension to 1.0 sigma, and improves Δχ^{2}_tot = -18.26 over Λ CDM.
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.

A self-consistent analytical model for both the photoionization rate and reionization history
A new analytical formalism self-consistently predicts both the ionized fraction x_i(z) and photoionization rate Gamma_HI(z), achieving percent-level accuracy in x_i and 20-30% accuracy in Gamma_HI versus radiative transfer simulations at z less than or equal to 6.

Resolving the Hubble Tension in the Early Dark Energy Framework with JWST and DESI Data
Axion EDE model fitted to Planck/ACT/SPT CMB, DESI BAO, and JWST UV luminosity function data yields H0 = 71.58 ± 1.05 km s^{-1} Mpc^{-1}, reduces H0 tension to 1.0 sigma, and improves Δχ^{2}_tot = -18.26 over Λ CDM.
