Distribution of galaxies (colored dots) in the fields of the Exemplar (left panel) and of the Double Irony (right panel). The dots are color-coded according to the galaxies’ spectroscopic redshifts in the GAMA database as indicated by the labels. The black contours correspond to the surface brightness at 610 MHz and increase by a factor of two from 0.3 to 4.8 mJy beam⁻¹. The arrows point toward the brightest areas of the radio lobes; the lines were extended to show the directions of the lobes more clearly. In the Exemplar, the SE lobe is longest (80′′ at a position angle of 120° measured from the N toward the E, shown in red); the shorter lobe (40′′, blue arrow) points in the opposite direction. In the Double Irony, the arrows point toward the SW lobe (PA = − 103°, in red) and toward the NE Elbow (PA = + 55° degrees, in blue) and have the same length (90′′). Some asymmetries can be seen: more galaxies lie ahead of the shorter (blue) lobe than on the side of the longer lobe in the Exemplar; in the Double Irony, there is an overdensity of galaxies in the NE, beyond the Elbow and the northern plume.
