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…

AGNFormer I: Reconstruction of AGN spectra using a probabilistic transformer model

Benedict L. Rouse, Franz E. Bauer, Tomasz Różański +8

We explore how an uncertainty-aware transformer-based architecture can leverage information embedded across the entire observed optical spectra of AGN, focusing on the algorithm's…

Resolved UV-Optical HST Imaging and Spectral Energy Distribution Modeling of Nearby BAT Active Galactic Nuclei

Connor Auge, Michael Koss, Kriti K. Gupta +17

We use high-resolution UV-to-optical imaging from the Hubble Space Telescope (HST) to construct spatially resolved spectral energy distributions (SEDs) for seven nearby ()…

BASS. LI. Cool gas supply of HI-massive local Seyfert galaxies

Jeein Kim, Aeree Chung, O. Ivy Wong +19

We present neutral atomic hydrogen (HI) imaging observations of 22 HI-rich (), hard X-ray-selected local Seyferts to explore how cool gas is su…

16 new quasars at the end of the reionization unveiled by self-supervised learning

L. N. Martínez-Ramírez, Julien Wolf, Silvia Belladitta +8

Luminous quasars at are key probes of early supermassive black hole (SMBH) growth, massive galaxy evolution, and intergalactic medium properties during cosmic reionization.…

Evidence of Gas Depletion in Quasars with Moderate Radio Emission

Yuhan Wen, Ran Wang, Luis C. Ho +4

The energy released by active galactic nuclei (AGNs) is considered to have a profound impact on the cold gas properties of their host galaxies, potentially heating or removing the…

Multi-wavelength properties of changing-state active galactic nuclei: I. the evolution of soft excess and X-ray continuum

Arghajit Jana, Claudio Ricci, Alessia Tortosa +11

Changing-state active galactic nuclei (CSAGNs) exhibit rapid variability, with mass accretion rates that can change by several orders of magnitude in a few years. This provides us…
