Pushing JWST to the extremes: search and scrutiny of bright galaxy candidates at z15-30

M. Castellano, A. Fontana, E. Merlin +50

We designed customized Lyman-break color selection techniques to identify galaxy candidates in the redshift ranges and . The selection was pe…

DeepDive: A deep dive into the physics of the first massive quiescent galaxies in the Universe

K. Ito, F. Valentino, G. Brammer +26

We present the DeepDive program, in which we obtained deep JWST/NIRSpec G235M/F170LP spectra for ten primary massive () quiescent galaxies at $z\…

Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn

S. Fujimoto, M. Ouchi, K. Kohno +43

Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…

COSMOS-Web: A history of galaxy migrations over the stellar mass-star formation rate plane

R. C. Arango-Toro, O. Ilbert, L. Ciesla +39

The stellar mass-star formation rate (-) plane is a fundamental diagnostic for distinguishing galaxy populations. However, the evolutionary pathways of…

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z<4

A. L. Faisst, L. Yang, M. Brinch +51

We study of the role of galaxy-galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with r…
