Star formation quenching precedes morphological transformation in COSMOS-WEB's richest galaxy groups

Z. Ghaffari, G. Gozaliasl, A. Biviano +26

We analyzed the 25 richest galaxy groups in COSMOS-Web at z = 0.18-3.65, identified via the AMICO algorithm. These groups contain 20-30 galaxies with high (>75%) membership probabi…

The ALPINE-CRISTAL-JWST Survey: JWST/IFU Optical Observations for 18 Main-Sequence Galaxies at z=4-6

A. L. Faisst, S. Fujimoto, A. Tsujita +80

To fully characterize the formation and evolution of galaxies, we need to observe their stars, gas, and dust on resolved spatial scales. We present the ALPINE-CRISTAL-JWST survey,…

COSMOS-Web: The emergence of the Hubble Sequence

M. Huertas-Company, M. Shuntov, Y. Dong +29

Leveraging the wide area coverage of the COSMOS-Web survey, we quantify the abundance of different morphological types from with unprecedented statistics and establish ro…

Not Just a Dot: the complex UV morphology and underlying properties of Little Red Dots

P. Rinaldi, N. Bonaventura, G. H. Rieke +31

We analyze 99 photometrically selected Little Red Dots (LRDs) at in the GOODS fields, leveraging ultra-deep JADES NIRCam short-wavelength (SW) data. We examine the…

COSMOS-Web: stellar mass assembly in relation to dark matter halos across of cosmic history

M. Shuntov, O. Ilbert, S. Toft +43

We study the stellar mass function (SMF) and the co-evolution with dark matter halos via abundance matching in the largest redshift range to date in $0.53 \, {\rm deg}^2…

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…
