COSMOS-Web: does halo mass alone shape the clustering of star-forming and quiescent galaxies?
Louise Paquereau, Clotilde Laigle, Henry Joy McCracken +29
While stellar mass correlates strongly with halo mass, it remains unclear whether halo mass alone governs galaxy star-formation activity, or whether secondary halo properties and e…
COSMOS-Web: A Multi-wavelength Morphological Catalog of ~780,000 Galaxies
Lilan Yang, Jeyhan S. Kartaltepe, Nicole E. Drakos +20
We present multi-wavelength morphological measurements for all galaxies in the COSMOS-Web survey, i.e., 780,000 galaxies contained in the COSMOS2025 catalog. We perform both…
The Small-scale Structures in the Wind of Messier 82
Yucheng Guo, Timothy Heckman, Sanchayeeta Borthakur +10
Small-scale multiphase structure plays a central role in galactic-wind evolution, yet the parsec-scale morphology and excitation of the warm ionised gas remain poorly constrained.…
The impact of cosmic filaments on starburst galaxies across cosmic times
Baptiste Jego, Matthieu Béthermin, Katarina Kraljic +17
Cosmological simulations suggest that various galaxy properties depend on their location within the cosmic web. Yet direct observational evidence of the dependence of star formatio…
Discovery and Analysis of a Type II Supernova Candidate at z = 3.19 from JWST's COSMOS-Web Survey
Valeria Aparicio, David O. Jones, Willem B. Hoogendam +21
The launch of the James Webb Space Telescope (JWST) has enabled the discovery of a small but increasing sample of high-redshift core-collapse supernovae (CC SNe), which provide new…
COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction
Greta Toni, Matteo Maturi, Gianluca Castignani +33
We investigate the redshift and group richness dependence of the quiescent fraction and red-sequence (RS) parameters in COSMOS galaxy groups from z=0 to z=3.7. We analyzed the deep…
