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 LIV. Physical Properties of AGN-Hosting Galaxy Mergers from Multiwavelength SED Fitting

Marco Troncoso, Ezequiel Treister, Alejandra Rojas +17

Galaxy mergers are believed to play an important role in triggering rapid supermassive black hole (SMBH) growth. As merging nuclei approach each other, the physical properties of t…

BASS LII: The prevalence of double-peaked broad lines at low accretion rates among hard X-ray selected AGN

Charlotte Ward, Michael J. Koss, Michael Eracleous +18

A fraction of active galactic nuclei (AGN) have double-peaked H, H and Mg II broad lines attributed to emission from rotating gas in the accretion disk. Using optical spectro…

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 BA…

BASS. XLIV. Morphological preferences of local hard X-ray selected AGN

Miguel Parra Tello, Franz E. Bauer, Demetra De Cicco +20

We present morphological classifications for the hosts of 1189 hard X-ray selected (14-195 keV) active galactic nuclei (AGNs) from the Swift-BAT 105-month catalog as part of the BA…

BASS XLVII: 22 GHz Radio Atlas of Swift-BAT Selected AGN

Macon Magno, Krista L. Smith, O. Ivy Wong +16

We present the third phase of the largest high-frequency, high-resolution imaging survey of 231 nearby, hard X-ray selected AGN, with a very high detection fraction. T…

Automatic Machine Learning Framework to Study Morphological Parameters of AGN Host Galaxies within in the Hyper Supreme-Cam Wide Survey

Chuan Tian, C. Megan Urry, Aritra Ghosh +8

We present a composite machine learning framework to estimate posterior probability distributions of bulge-to-total light ratio, half-light radius, and flux for Active Galactic Nuc…

BASS XLV: Quantifying AGN Selection Effects in the Chandra COSMOS-Legacy Survey with BASS

Yarone M. Tokayer, Michael J. Koss, C. Megan Urry +11

Deep extragalactic X-ray surveys, such as the Chandra COSMOS-Legacy field (CCLS), are prone to be biased against active galactic nuclei (AGN) with high column densities due to thei…
