Quasar 3C 190 (centre) shown in an HST WFPC2 F702W image, where numerous satellite galaxies, a prominent linear feature, and extended diffuse emission can be seen (Stockton & Ridgway 2001) associated with the system. Superimposed are MERLIN 1658 MHz radio contours at σ ⋅ log₅([1, 1.5, 2, 2.5, 3, 3.5]) mJy beam⁻¹, showing the 22 kpc extent of the lobe hot spots. While 3C 190 is a steep spectrum source, it has a flat spectrum core, and thus we expect low-frequency emission to arise in the radio lobes.
