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…

Euclid: A UV-faint quasar in a highly luminous star-forming host galaxy at

S. Belladitta, R. Decarli, E. Bañados +180

Constraining the co-evolution of supermassive black holes and their host galaxies in the first billion years after the Big Bang is essential for understanding the formation of the…

Lensing-Reconstructed Dark Matter-Intracluster Medium Coherence as a Probe of Cluster Dynamical State: Application to HSTFF, RELICS, and CLASH Clusters

Giulia Cerini, Sayan Saha, Jacqueline McCleary +13

We present the first application of Fourier-space coherence analysis between the lensing-reconstructed projected mass distribution and the X-ray-emitting intracluster medium to a s…
