JWST data show the clumpy galaxy fraction increasing from ~10% at z~7.75 to ~70% at z~2.75 for log(M*/Msun) >=9, with mass dependence and suggested formation mechanisms differing by epoch.

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.

The Fraction of Clumpy Galaxies in JADES over $2<z<9$
JWST data show the clumpy galaxy fraction increasing from ~10% at z~7.75 to ~70% at z~2.75 for log(M*/Msun) >=9, with mass dependence and suggested formation mechanisms differing by epoch.

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.
