Abstract: To better understand how galaxies assemble their structure and evolve over cosmic time, we present a new catalog of morphological measurements for over 340,000 sources spanning $0 3$. Quiescent galaxies also show significantly higher stellar mass surface densities, nearly an order of magnitude greater at $z sim 4$ than at $z sim 1$. Our results confirm a strong and evolving link between morphology and star formation activity, and support a scenario in which bulge growth and quenching are closely connected. This work is a highly valuable addition to the DJA, adding a morphological dimension to this rich dataset and thus enabling a wider scientific application.arXiv:2505.21622v1 Announce Type: new
