Extreme Variability Reveals How the Eddington Ratio Regulates Coronal Power in Active Galactic Nuclei

Arghajit Jana, Claudio Ricci, Franz E. Bauer +13

The bolometric luminosity () of active galactic nuclei (AGNs) is a key tracer of accretion physics, but its direct determination is often hindered by limited spectral…

The Extreme Rarity and Physical Properties of Low-redshift AGNs with Balmer Absorption

Jinyi Shangguan, Chang-Hao Chen, Luis C. Ho +6

Balmer absorption lines are increasingly observed in the little red dots (LRDs) discovered by the James Webb Space Telescope, potentially tracing dense circumnuclear gas around rap…

ABCD: The Nuclear Structure of the Little Red Dots Revealted through Absorption, Break, Continuum, and Decrement

Chang-Hao Chen, Jinyi Shangguan, Luis C. Ho +3

We present a spectroscopic analysis of 14 little red dots (LRDs) at redshifts using NIRSpec/MSA prism and medium-resolution grating observations, aiming to constrai…

UGC 2369S: a Kpc Scale Triple Merger Candidate Identified in a Nearby Luminous Infrared Galaxy

Yuanze Ding, Michael J. Koss, Fiona A. Harrison +12

We present high spatial resolution (1.0''), multi-wavelength observations of UGC 2369S, a nearby luminous infrared galaxy showing three distinct cores separated on kpc sc…

Direct pathway to the Early Supermassive Black Holes: A Red Super-Eddington Quasar in a Massive Starburst Host at

Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +24

We present a panchromatic optical-mm characterization of GNz7q, a recently identified X-ray weak, rapidly growing red quasar embedded within a dusty starburst galaxy at ,…

Discovery of a gas-enshrouded broad-line AGN at z 7

Qianqiao Zhou, Xin Wang, Hang Zhou +9

The Lyman-alpha (Ly) absorption profile in star-forming galaxies serves as a powerful tracer of the extended, dense neutral hydrogen in their surroundings during the Epoch of Re…
