A new fitting methodology applied to UV absorption data recovers radial trends in galactic wind velocities and mass-loading factors by constraining initial hot and cool phase parameters in a multiphase model.
AGN activity in Mrk 573 enriches the surrounding gas with metals up to several times solar abundance on 100-parsec scales via outflows and jets.
A transition to low-opacity SNe-produced dust at z>9 reproduces the observed low attenuation and UV luminosity function excess in early galaxies.
Simulations of dwarf galaxies show V/σ rising with stellar mass, with HI gas and young stars more rotation-supported than old stars.
Milky Way abundance trends act as effective empirical proxies for nucleosynthetic yields, recovering alpha and Fe-peak abundances in quiescent galaxies with 0.05 dex median offset versus 0.23 dex for theory, indicating largely universal yields.
New VLT observations of He I* absorbers yield a primordial ³He/⁴He ratio of (1.15^{+0.24}_{-0.21})×10^{-4} consistent with standard Big Bang nucleosynthesis, plus an updated stellar yield scaling factor.
Bursty stellar feedback produces systematically flatter metallicity gradients than smooth feedback in high-redshift galaxies across multiple simulation suites.
FIRE-2 simulations find metallicity gradients in EoR galaxies flatten from median -0.15 dex/kpc at z~10 to -0.1 at z~6, with positive correlations to stellar mass and gas flow proxy Δv/2σ and links to central SFR density.
Coevolving super-Eddington black holes and nuclear starbursts in high-redshift halos naturally generate the V-shaped UV-to-optical spectra and weak high-energy emission of little red dots.
New empirical calibrations between 19 emission-line ratios and oxygen abundance are derived from direct electron-temperature measurements in 139 star-forming galaxies at z=1.4-10.6.
A z=2.96 protocluster in COSMOS shows +0.2 dex higher stellar masses, mild SFR enhancement in low-mass galaxies, and no rise in quiescent fraction compared to the field.
Rest-frame 6-8um MIRI luminosity provides broken power-law SFR calibrations with 0.2-0.3 dex scatter and UV+IR composites at 0.15 dex, supporting robust use above log M* ~9 up to z~3.
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.
