2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/13019We have discovered an obscured active galaxy at redshift z = 1.246 identified with the ROSAT X-ray source RX J1011.2+5545. We report on multiwavelength observations of this source and discuss its X-ray, optical and radio properties. This is the first X-ray selected, obscured active galaxy at high redshift to be shown to be radio-loud, with a radio counterpart exhibiting a classical double-lobe morphology.5 pages, 6 ps figures included, uses mn.sty.
