Lumina is a 500 cMpc radiation-hydrodynamic simulation predicting late, stellar-driven hydrogen reionization ending near z≈4.75 and AGN-driven helium reionization nearly complete by z=3.
COLIBRE simulations find the galaxy gas-phase MZR already in place at z≈10 with little evolution until z≈5, then shallowens at low z, with high-mass turnover set by AGN feedback and low-mass end by core-collapse supernovae.
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 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.
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.
Five LRDs at z≈2 yield number density ≈7×10^{-6} cMpc^{-3}, confirming a decline from the z≈5 peak but gentler than prior photometric estimates.
JWST IFU spectroscopy of six z~6 galaxies finds broad Balmer lines in two objects, a strong correlation of broad-line presence with Lyα luminosity yielding AGN fractions >77% above and <15% below 10^44 erg/s, plus extended star-forming gas in non-AGN hosts.
JWST spectra reveal that two z~7 galaxies already show near-solar iron-to-silicon ratios with no strong odd-even effect, favoring early Type Ia supernovae over pair-instability supernovae as the source of iron enrichment.
A multiphase ISM grain-size model with low supernova dust yield reproduces observed dust-to-stellar mass ratios and UV luminosity functions at z=7-12 by letting small grains seed rapid metal accretion.
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.
TNG100 and EAGLE hydrodynamical simulations underproduce faint compact galaxies at z>3 relative to CANDELS observations even after forward modeling and completeness corrections, with the mismatch linked to both detection effects and simulation physics.
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.
Two high-redshift galaxy candidates are reidentified as ultra-cool Y-type brown dwarfs at ~500 pc based on NIRSpec spectra matching templates and detected proper motions of 49 and 24 mas/yr.
Multi-element Bayesian modeling of 23 EELGs reveals short depletion timescales and large mass-loading factors in a burst-driven regime, with abundance ratios isolating star-formation efficiency, outflows, and inflows.
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.
Lower metallicity in high-redshift tori raises the X-ray escape fraction from Compton-thick obscurers, improving prospects for detecting z~10 AGNs.
A mission-proposal science book forecasting observational yields for a proposed JAXA 2–18 µm infrared space telescope; no new measurement or derivation is presented.
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.
A sparse population of primordial charged compact objects is hypothesized with specific parameters and shown to face severe plasma-screening and neutralization constraints while failing to produce late-time acceleration in the homogeneous FLRW approximation.
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.
Synthesizes simulation predictions and pathfinder data to outline a broadband radio SED and spectral curvature strategy for identifying the earliest radio AGN with the SKA.
