Title: J021659-044920: A relic giant radio galaxy at z ~ 1.3
Author: Prathamesh Tamhane, Yogesh Wadadekar, Aritra Basu, Veeresh Singh, C. H. Ishwara-Chandra, Alexandre Beelen, Sandeep Sirothia

We report the discovery of a relic Giant Radio Galaxy (GRG) J021659-044920 at redshift z~1.3 that exhibits large-scale extended, nearly co-spatial, radio and X-ray emission from radio lobes, but no detection of AGN core, jets and hot-spots. The total angular extent of the GRG at the observed frame 0.325 GHz, using GMRT observations is found to be ~ 2'.4, that corresponds to a total projected linear size of ~ 1.2 Mpc.
