Gaia GraL X.: The GraL catalogue of gravitationally lensed quasars Matched with \textit{Gaia} data, redshifts, and time delays
C. Ducourant, R. Teixeira, P. H. Vale-Cunha +25
Determining the Hubble constant tension requires alternative strategies, and multiply imaged quasars, with their intermediate redshifts, can potentially be used in this regard. We…

QZO: A Catalog of 5 Million Quasars from the Zwicky Transient Facility
S. J. Nakoneczny, M. J. Graham, D. Stern +11
Machine learning methods are well established in the classification of quasars (QSOs). However, the advent of light curve observations adds a great amount of complexity to the prob…
