2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/12573We present the discovery of a z=4.13 galaxy TN J1338-1942, the most distant radio galaxy in the southern hemisphere known to date. The source was selected from a sample of Ultra Steep Spectrum (USS; alpha < -1.3) radio sources using the Texas and NVSS catalogs. The discovery spectrum, obtained with the ESO 3.6m telescope, shows bright extended Ly-alpha emission. The radio source has a very asymmetric morphology, suggesting a strong interaction with an inhomogeneous surrounding medium.2 Pages, including 2 PostScript figures; To appear in "Looking Deep in the Southern Sky" eds R.Morganti & W.J.Couch, Proc. of ESO/Australia Workshop, Dec 97 SydneyAstrophysicstext
