    Finding Lensed Radio Sources with the Very Large Array Sky Survey by Michael N. Martinez, Yjan A. Gordon, Keith Bechtol, Gillian Cartwright, Peter S. Ferguson, Miranda Gorsuch

    Published 2025-01-01
    “…\limits^{\unicode{x02033}}$ 2) VLA follow-up observations for 11 targets that we identify using three different techniques: (i) a search for compact radio sources offset from galaxies with high lensing potential, (ii) VLASS detections of known lensed galaxies, and (iii) VLASS detections of known lensed quasars. Five of our targets show radio emission from the lensed images, including 100% of the lensed optical quasar systems. …”

    The Hobby–Eberly Telescope Dark Energy Experiment Survey (HETDEX) Active Galactic Nuclei Catalog: The Fourth Data Release by Chenxu Liu, Karl Gebhardt, Erin Mentuch Cooper, Dustin Davis, Donald P. Schneider, Matt J. Jarvis, Daniel J. Farrow, Steven L. Finkelstein, Óscar A. Chávez Ortiz, The HETDEX Collaboration

    Published 2025-01-01
    “…Among them, 10,499 (66%) have redshifts either confirmed by line pairs or matched to the Sloan Digital Sky Survey Quasar Catalog. For the remaining 5441 AGN, 2083 are single broad-line AGN candidates, while the remaining 3358 are single intermediate broad-line (full width at half-maximum, FWHM ∼1200 km s ^−1 ) AGN candidates. …”
