Large-scale Environmental Dependence of AGN Activity Revealed by JWST Pa Emitters

Danyang Jiang, Linhua Jiang, Shuqi Fu +7

The role of the large-scale environment in regulating AGN activity remains an open question. We investigate the Mpc-scale environments of 70 AGNs at - using a highly co…

Hot Molecular Hydrogen in Galaxies at Redshift ~ 0.2-1.5 Revealed by JWST

Jie Chen, Linhua Jiang, Shuqi Fu +5

Molecular hydrogen (H) is the fundamental component of the molecular gas reservoir that fuels star formation and black hole growth. While prominent hot H emission ($\gtrsim…

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…

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…

The relationship between morphology, density, and location in the cosmic web from massive to dwarf galaxies

Ilin Lazar, Sugata Kaviraj, Aaron E. Watkins +5

We study how morphology relates to environment from massive to dwarf galaxies using, for the first time, a mass-complete sample of ~13,000 galaxies, in the stellar-mass and redshif…

Global trends in morphology from massive to dwarf galaxies

Ilin Lazar, Sugata Kaviraj, Christopher J. Conselice +7

The morphological properties of dwarf galaxies (Mstar < 10^9.5 MSun) remain largely unexplored, particularly outside the local neighbourhood. We explore how morphology changes acro…

Reference File Updates Following the Application of New Geometric Distortion and Walk Corrections I: Overview

Nick Indriolo, William J. Fischer, Elaine Frazer +8

The calibration of Cosmic Origins Spectrograph (COS) data is performed by the data processing pipeline known as CalCOS. CalCOS utilizes several reference files that store informati…

Downsizing does not extend to dwarf galaxies: identifying the stellar mass regimes shaped by supernova and AGN feedback

Ilin Lazar, Sugata Kaviraj, Garreth Martin +10

We explore how the fraction of red (quenched) galaxies varies in the dwarf galaxy regime (10^7 MSun < Mstar < 10^9.5 MSun), using a mass-complete sample of ~5900 dwarfs at z<0.15,…

Multi-wavelength morphology and dust emission in low-redshift dwarf galaxies in COSMOS-Web with HST and JWST

D. Kakkad, I. Lazar, S. Harish +18

Low-mass or dwarf galaxies (M M) are abundant in the Universe, yet their formation and evolution remain poorly understood. Their enhanced sensitivity to fe…

The Quasar Feedback Survey: Revealing the importance of sensitive radio imaging for AGN identification deeper into the radio-quiet regime

Ann Njeri, Chris M. Harrison, Preeti Kharb +8

We present new sub-arcsecond (0.3-1 arcsec; 1--3\,kpc) VLA imaging at 1.4\,GHz and 6\,GHz of 29 optically-selected, [O~{\sc iii}] luminous ( > 10$^{42.…
