PKS2058-28
(Top) 5GHz
(Middle) Image of 2058-28 at 6-cm (low resolution) with superimposed vectors indicating the projected electric field direction. The vectors are proportional in length to the fractional polarisation (1 arcsec = 0.04 ratio). (Bottom) The contour levels are: , 1, 2, 3, 4, 6, 8, 16, 32, 64 mJy beam-1. The peak flux is 112.0 mJy beam-1. Zoom-in of the jet in 2058-28 at 6-cm (full resolution) with superimposed vectors indicating the projected electric field direction. The vectors are proportional in length to the fractional polarisation (1 arcsec = 0.13 ratio). The contour levels are: , 1, 2, 3, 4, 6, 8, 16, 32, 64 mJy beam-1. The peak flux is 100.6 mJy beam-1.

Notes
The radio morphology of this FRI source shows a strong jet. A low resolution radio image was obtained by Christiansen et al. (1977) and shows that the source is embedded in a low brightness halo, extended more than 8 arcmin, which is not visible in our image.
Two diffuse lobes without hot-spots are observed. The polarisation in these lobes has a ring-like shape and the position angle of the electric field is radial in both the lobes.
In the optical spectrum, weak [OIII]λ5007 and Hα emission lines of comparable strength are observed. The continuum colours appear typical of early-type galaxies.
