Abstract. Using 1.4 GHz ATCA & VLA images with 5.5 GHz ATCA data, we present a sample of 12 bent-tailed galaxies over the 4 deg2 area of the Chandra Deep Field South (CDFS). We find 10 new sources, one of which is possibly the highest red-shift bent-tailed galaxy detected at z ∼ 2. Key words. Extended radio sources—head–tail galaxies. 1. CDFS bent-tailed galaxies Bent-tailed sources are found almost exclusively in rich clusters of galaxies in the local Universe (z ≤ 1), and their curvature is believed to result of interaction Figure 1. Bent-tailed sources detected in the CDFS field; Radio contours at 1.4 (ATCA – blue, VLA – red) and 5.5 (ATCA – black) GHz overlaid on optical images from the SWIRE and DSS. Countours begin at 3σ and increase at intervals of 2 for all frequencies. Sources ordered left to right as per Table 1. 49
