Top left panel: total intensity radio contours at 1400 MHz (VLA in D configuration) with an FWHM of 50′′ × 50′′. The contour levels are − 0.15 mJy/beam, 0.15 mJy/beam, and the rest are spaced by a factor 2. Top right panel: total intensity radio contours at 1400 MHz (VLA data in C configuration) with an FWHM of 16′′ × 16′′. The contour levels are − 75 μJy/beam, 75 μJy/beam, and the rest are spaced by a factor 2. The contours of the radio intensity are overlaid on the red plate of the Sloan Digital Sky Survey. Bottom panel: total intensity radio contours at 1400 MHz (combining VLA data in C and D configuration) with an FWHM of 26′′ × 26′′. The contour levels are − 90 μJy/beam, 90 μJy/beam, and the rest are spaced by a factor . The contours of the radio intensity are overlaid on the ACIS-I Chandra X-ray adaptively smooth brightness image in the 0.8–4 keV band (Govoni et al. 2004) in colors.
