Prevalence of radio Active Galactic Nuclei in galaxy groups since z=3.5 in the COSMOS-Web field
F. Ubertosi, I. Delvecchio, I. Prandoni +30
Radio active galactic nuclei (AGN) are key tracers of kinetic feedback from supermassive black holes. Although the dependence of their triggering on host stellar mass is well known…
X-ray Characterization of Galaxy Groups and Hickson Groups in COSMOS-Web to z~3.8 I. X-ray Luminosity Function Evolution
Ghassem Gozaliasl, Günther Hasinger, Gavin Leroy +35
Galaxy groups are the dominant halo environment in the Universe and a sensitive laboratory for feedback and gas-cycling physics, yet a uniform, intermediate-redshift X-ray characte…
Do Submillimeter Galaxies Trace Megaparsec Large-scale Structures? -- An Overdensity Analysis of 449 Submillimeter Galaxies in COSMOS
Canze Deng, Daizhong Liu, Helmut Dannerbauer +19
We present an environmental analysis and overdensity catalog for a large sample of submillimeter galaxies (SMGs) in the COSMOS field in order to understand whether SMGs are signpos…
Rest-Frame UV and Optical Structural Evolution of Narrowband-Selected Lyman-alpha Emitters at z = 2-7 with JWST/NIRCam
Ronaldo Laishram, Haruka Kusakabe, Satoshi Kikuta +8
We present a systematic study of the rest-frame ultraviolet (UV) and optical morphologies of Ly emitters (LAEs) at - from the SILVERRUSH multi-narrowband catalog,…
COSMOS-Web: From early star-formation enhancement to late suppression in galaxy groups
R. C. Arango-Toro, C. Laigle, J. Lewis +29
Galaxy groups trace dense environments where interactions, gas removal, and reduced accretion may drive quenching. Common diagnostics trace star formation over short timescales ($\…
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…
COSMOS-Web: Galaxy Size and Surface Brightness Evolution at Rest-Frame 1.22 m Since
Si-Yue Yu, Andreas L. Faisst, Taotao Fang +7
We present the evolution of galaxy size and surface brightness in the rest-frame band (1.22 m), tracing the stellar mass distribution, over , using a samp…
Molecular gas properties of star-forming brightest group galaxies at
Greta Toni, Gianluca Castignani, Françoise Combes +4
Recent efforts to characterise the molecular gas content of brightest cluster galaxies (BCGs) at intermediate redshift have revealed a sub-population of gas-rich systems, whose sta…
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…
Sparse by the River: Diverse Environments of z > 3 Massive Quiescent Galaxies
Nguyen Binh, Arianna S. Long, Jacqueline Antwi-Danso +29
High-redshift (), massive quiescent galaxies (QGs) offer a significant window into early Universe galaxy formation. Previous works have predicted miscellaneous properties fo…
Large-Scale Structure in COSMOS-Web: Tracing Galaxy Evolution in the Cosmic Web up to with the Largest JWST Survey
Hossein Hatamnia, Bahram Mobasher, Sina Taamoli +31
We present a reconstruction of the large-scale structure using the James Webb Space Telescope's (JWST) COSMOS-Web program to trace environmentally driven galaxy evolution up to $z\…
The stellar mass function of quiescent and star-forming galaxies and its dependence on morphology in COSMOS-Web
Marko Shuntov, Olivier Ilbert, Claudia del P. Lagos +33
We study the stellar mass function (SMF) of quiescent and star-forming galaxies and its dependence on morphology in 10 redshift bins at using the COSMOS2025 catalog bui…
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…
