JWST/NIRCam imaging and Keck/MOSDEF spectroscopy identify COSMOS-74706 as an unlensed barred spiral galaxy at z_spec=3.159, with the bar confirmed via residuals, ellipse fitting, and Fourier modes.

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.
Clumps in high-redshift spiral galaxies are smaller than commonly reported, spatially concentrated toward spiral arms, smaller but brighter inside arms than between them, with similar colors, suggesting arms stimulate clump formation but do not alter their star formation properties.
A new sample of 157 mid-IR dual AGN candidates in mergers yields 13 confirmed cases and 63 strong candidates at separations 14.5-129 kpc, over half beyond 50 kpc, with diverse BPT classes and 31% in multi-mergers.
GalCatDiff applies category embeddings and a novel Astro-RAB block inside diffusion models to produce galaxy images whose color and size distributions match observations more closely than prior generative approaches.

Spiral arms across cosmic time: JWST measurements of the pitch angles of spiral galaxies at $z<3.5$
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.

Clumps in spiral galaxies at $z \lesssim 3$: Disentangling two spatial modes of star formation
Clumps in high-redshift spiral galaxies are smaller than commonly reported, spatially concentrated toward spiral arms, smaller but brighter inside arms than between them, with similar colors, suggesting arms stimulate clump formation but do not alter their star formation properties.
