BASS.L. Near-infrared Data Release 3: A Spectral Atlas and Characterization of AGN

Jarred Gillette, Michael J. Koss, Darshan Kakkad +18

We present an analysis of near-infrared (NIR) emission-line properties, AGN diagnostics, and circumnuclear gas dynamics for 453 hard X-ray selected (14195 keV) AGN from the BAT…

ALMA and JWST Identification of Faint Dusty Star-Forming Galaxies up to z~8

Jorge A. Zavala, Andreas L. Faisst, Manuel Aravena +44

We exploit a new sample of around 400 bright dusty galaxies from the ALMA CHAMPS Large Program, together with the rich JWST multi-band data products in the COSMOS field, to explore…

The relationship between warm and hot gas-phase metallicity in massive elliptical galaxies and the influence of AGN feedback

Valeria Olivares, Yuanyuan Su, Pasquale Temi +10

Warm ionized gas is ubiquitous at the centers of X-ray bright elliptical galaxies. While it is believed to play a key role in the feeding and feedback processes of supermassive bla…

Molecular Gas in Major Mergers Hosting Dual and Single AGN at <10 kpc Nuclear Separations

Makoto A. Johnstone, Ezequiel Treister, Franz E. Bauer +24

We present high-resolution (50100 pc) Atacama Large Millimeter Array (ALMA) observations of CO(2-1) or CO(1-0) emission in seven local ( 0.05)…

Discovery of a Little Red Dot candidate at in COSMOS-Web based on MIRI-NIRCam selection

Takumi S. Tanaka, Hollis B. Akins, Yuichi Harikane +64

JWST has revealed a new high-redshift population called little red dots (LRDs). Since LRDs may be in the early phase of black hole growth, identifying them in the early universe is…

Insights for Early Massive Black Hole Growth from JWST Detection of the [Ne v] λ3427 Emission Line

Benny Trakhtenbrot, Claudio Ricci, Ezequiel Treister +7

We use the narrow [Ne v] 3427 emission line detected in the recently published JWST spectra of two galaxies, at z = 6.9 and 5.6, to study the key properties of the active galac…
