BASS LV. Connecting X-ray variability with AGN physical properties and a new path to Cosmological distances
Matilde Signorini, Federica Ricci, Alessia Tortosa +18
X-ray variability is a well-established characteristic of active galactic nuclei (AGN), known to correlate inversely with both the supermassive black hole mass and luminosity, alth…
16 new quasars at the end of the reionization unveiled by self-supervised learning
L. N. MartÃnez-RamÃrez, 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.…
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…
BASS LIII: The Eddington Ratio as the Primary Regulator of the Fraction of X-ray Emission in Active Galactic Nuclei
Kriti Kamal Gupta, Claudio Ricci, Alessia Tortosa +20
Active galactic nuclei (AGN) emit radiation via accretion across the entire energy spectrum. While the standard disk and corona model can somewhat describe this emission, it fails…
BASS. XLIX. Characterization of highly luminous and obscured AGNs: local X-ray and [NeV]3426 emission in comparison with the high-redshift Universe
Alessandro Peca, Michael J. Koss, Kyuseok Oh +21
We present a detailed analysis of the most luminous and obscured Active Galactic Nuclei (AGNs) detected in the ultra-hard X-ray band (14-195 keV) by Swift/BAT. Our sample comprises…
BASS XLVIII: [Ne v] λ3427 Emission in Powerful Nearby Active Galactic Nuclei
Tomer Reiss, Benny Trakhtenbrot, Claudio Ricci +14
We investigate the high-ionization, narrow [Ne v] 3427 emission line in a sample of over 340 ultrahard X-ray (14-195 keV) selected Active Galactic Nuclei (AGN) drawn from the B…
