'''3C 236''' is the name used for this Fanaroff and Riley Class II (FR II) radio galaxy. It is among the largest known radio galaxies; the radio structure has a total linear size in excess of 4.5 Mpc (15 million light years). The galaxy features a "double-double" radio morphology consisting of the giant relic 4.5 Mpc source and an inner 2 kpc compact steep spectrum radio source. A recent starburst episode near the nucleus may be related to the event resulting in re-ignition of radio activity.<ref name="Tremblayetal2010">{{citation | url = http://adsabs.harvard.edu/cgi-bin/bib_query?arXiv:1004.0388 | title = Episodic Star Formation Coupled to Reignition of Radio Activity in 3C 236 | author = Tremblay, Grant R. | author2 = O'Dea, Christopher P. | author3 = Baum, Stefi A. | author4 = Koekemoer, Anton M. | author5 = Sparks, William B. | author6 = de Bruyn, Ger | author7 = Schoenmakers, Arno P. | date = April 2010 | journal = The Astrophysical Journal | volume = 715 | issue = 1 | pages = 172–185 | doi = 10.1088/0004-637X/715/1/172 |bibcode = 2010ApJ...715..172T |arxiv = 1004.0388 | s2cid = 119111278 }}</ref> ==Notes== {{notelist}}
