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…

VAR-PZ: Constraining the Photometric Redshifts of Quasars using Variability

S. Satheesh-Sheeba, R. J. Assef, T. Anguita +33

The Vera C. Rubin Observatory LSST is expected to discover tens of millions of new Active Galactic Nuclei (AGNs). The survey's exceptional cadence and sensitivity will enable UV/op…

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…
