High-resolution zoom-in simulation of a z~10 galaxy produces over 10^5 star clusters with scale-free mass function, 90% of star formation in clusters, global SFE 0.2-0.3, and reproduces JWST super-bright galaxies via feedback-free bursts.

Empirical three-parameter fit to f_esc(M_h,z) yields steep redshift evolution with population-averaged escape fraction rising from ~2% at z=5 to ~9% at z=12.
A transition to low-opacity SNe-produced dust at z>9 reproduces the observed low attenuation and UV luminosity function excess in early galaxies.
Corrected empirical limits show the most massive galaxies never exceed the theoretical baryonic maximum of 0.16 times halo virial mass, keeping observations consistent with LambdaCDM at all redshifts.
The size-mass relation for star-forming galaxies at 0.6 < z ≤ 4 shows a gradient in slope with rest-frame wavelength, crossing at ~10^9.5 solar masses proposed as the transition between diffuse and compact morphologies.
JADES DR5 delivers a public catalog of Bayesian-inferred stellar masses, SFRs, SFHs, dust, metallicities, and AGN contributions for ~500k galaxies via Prospector with an evolving SFMS prior.
An algebraic degeneracy makes all reionization-history observables sensitive only to the product of escape fraction and star formation efficiency, explaining parameter tensions and limiting dark matter constraints from reionization data.
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.
Extreme-value statistics applied to JWST high-redshift galaxy data predicts a black hole to stellar mass ratio of approximately 0.24.
Strong-feedback models with bright galaxies match JWST UVLF at z greater than or equal to 10 and predict an extended reionization from z approximately 16 to 6 that fits CMB optical depth within 2 sigma.
Shorter star formation timescales in a semi-analytical UV LF model explain the slow evolution observed by JWST at z>10 without requiring changes in star formation efficiency.
Renaissance Simulations produce galaxies at z>10 whose stellar masses, star formation rates, sizes, and colors overlap with JWST observations while extending to lower masses.
Simulations predict ngVLA at 100 GHz can detect galaxies above 10^9 solar masses at any redshift while SKA low frequencies reach massive dusty galaxies to z=5-7.
Simulations show that bursty supernova feedback produces fewer bright [OIII] emitters by z=5 than smooth feedback due to less effective metal enrichment, while [OIII] traces shock-heated and radiatively ionized gas.
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.
Hα luminosity functions at z~1.3 and z~2.0 yield faint-end slopes of -1.50 and -1.60, with integrated SFR densities of 0.097 and 0.129 M⊙ yr⁻¹ Mpc⁻³ from a sample of 99 emitters.
