IC 4296: a double-double radio galaxy

Abstract
Observations of the large, nearby radio galaxy PKS 1333–33 (IC 4296) have been made at 1415 MHz with a resolution of 50 arcsec using the Fleurs Synthesis Telescope. Previous work had shown the source to be triple with the outer double separated by 30 arcmin (680 kpc); the present work shows that the central source is also double with a separation of 2 arcmin ( 45 kpc ). The inner and outer doubles have the same orientation.
