Image of 0453-20 at 6-cm. The contour levels are: , 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 25, 30, 40, 50,75 mJy beam-1. The peak flux is 30.4 mJy beam-1. Image of 0453-20 at 6-cm with superimposed vectors indicating the projected electric field direction. The vectors are proportional in length to the fractional polarisation (1 arcsec = 1.7 ratio). The contour levels are: , 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 25, 30, 40, 50, 75, 100 mJy beam-1

    The optical spectrum reveals no emission lines, and the optical continuum shows a UV excess compared with quiescent elliptical galaxies (Tadhunter et al. 1993, Wills et al. 2004) .

    The radio image (Morganti et al. 1999) of this source appears double lobed, with a clear jet in the north-west direction ending with an hot spot. In the southern part no jet has been detected and a "warm-spot'' is visible at the edge of the lobe. The electric field is parallel to the direction of the jet and becomes radial at the edge of the lobe.

    Wills et al. (2004) find evidence for young stellar populations in this source. On the western side of this galaxy, the residual K-band near-infrared flux image shows excess flux beyond the slightly over-subtracted region surrounding the nucleus, suggestive of some underlying asymmetry in the host galaxy (Inskip et al. 2010).
