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…
CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm
Felix Martinez, Jeyhan S. Karaltepe, Andreas L. Faisst +52
We present the reduction and source catalogs for the \textit{COSMOS High- ALMA-MIRI Population Survey} (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank fie…
CHAMPS: The COSMOS High-Redshift ALMA-MIRI Population Survey - A New Census of the Dusty Early Universe
Andreas L. Faisst, Felix Martinez, Jeyhan S. Kartaltepe +86
Understanding how dust forms and evolves over cosmic time is a key open problem in extragalactic astrophysics. Galaxies in the early Universe were once thought to be mostly dust-po…
COSMOS-3D: Diverse Environments and Hot-dust Signatures among Dusty Star-forming Galaxies at = 4.9-7.2
Siwei Zou, Manuel Aravena, Shaoze Geng +20
Dusty star-forming galaxies (DSFGs) are expected to trace early massive-halo assembly, but the connection between dust-obscured star formation, morphology, hot dust, and environmen…
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,…
Tracing Cold Gas in Absorption Across Cosmic Time with the SKA
Elizabeth K. Mahony, Neeraj Gupta, Sergei A. Balashev +12
Observing the 21-cm HI line in absorption provides a powerful means of tracing the cold neutral gas in normal and active galaxies across cosmic time. The frequency coverage and sen…
