JWST measurements of pitch angles in 593 spiral galaxies to z=3.5 show no overall redshift evolution but reveal correlations with mass and sSFR only below z=1.25, implying a transition from locally driven to globally regulated spiral arms.

A Hubble-like sequence of galaxy morphologies exists by redshift 4, with low-mass galaxies as persistent star-forming disks and massive galaxies following either stable disk or rapid compaction-quenching paths.
Morphological metrics in galaxy images suffer systematic biases from resolution, depth, and noise that can be quantified and corrected empirically, with new metrics proposed to reduce those effects.
The clumpy-galaxy fraction rises from ~20% at z>6.5 to ~80% at z~2.75 in a 9,121-galaxy JWST sample, higher than HST-based values because JWST detects fainter clumps.
Star clusters forming in cosmic filaments at z≈7.6 are systematically slow rotators, and a gas-rich subset overlaps the kinematic and density locus of Milky Way globular clusters, making them plausible proto-globular clusters.
A galaxy at z=3.16 has a bar with older stars making up 30% of its mass but only 8% of its recent star formation, supporting inside-out galaxy formation and possible early bar quenching.
Barred galaxies transition from actively star-forming at z~1-2 to quiescent at z~0, with the fraction of quiescent galaxies hosting bars increasing steeply over cosmic time.
JWST observations of high-redshift galaxies show no evolution in dust geometry to z~2.4 and yield an empirical calibration linking resolved differential reddening to SFR surface density.
BonFIRE and CampFIRE simulations show bursty clustered star formation in early galaxies and predict UV luminosity functions matching observations at faint magnitudes with a turnover at M_UV approx -14 but overpredicting brighter galaxies.
Neo, a cGAN, super-resolves HSC images to HST-like quality and improves galaxy morphological parameter accuracy by factors of 2-10.
TNG50 shows most massive high-z star-forming galaxies are dynamically hotter than ALMA data indicate, with rare cold discs forming from aligned accretion and evolving into one-third discs and two-thirds early-type galaxies by z=0.
Resolved stellar property gradients in Milky Way analog progenitors show inside-out assembly with minor, temporary disruption from major mergers.
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.
