X-ray selected broad absorption line quasars in SDSS-V: BALs and non-BALs span the same range of X-ray properties
Pranavi Hiremath, Amy L. Rankine, James Aird +10
Broad absorption line (BAL) quasars are often considered X-ray weak relative to their optical/UV luminosity, whether intrinsically (i.e., the coronal emission is fainter) or due to…

BAL Outflows are common in Low Eddington Ratio AGN
M. Vivek, Dominika Wylezalek
Broad absorption line (BAL) quasars exhibit significant outflows, offering insights into active galactic nuclei (AGN) feedback. While typically associated with high Eddington ratio…

Spectroscopic Quasar Anomaly Detection (SQuAD) I: Rest-Frame UV Spectra from SDSS DR16
Arihant Tiwari, M. Vivek
We present the results of applying anomaly detection algorithms to a quasar spectroscopic sub-sample from the SDSS DR16 Quasar Catalog, covering the redshift range 1.88 < z < 2.47.…
