Fig. 4

image

Left panel: radio halo in A 2142 overlaid on the XMM–Newton emission. The 234 MHz image is shown in black (negative contours in yellow). Contour levels are drawn at ±2.5, 4, 8 mJy b-1, θ = 44.86′′ × 40.96′′, PA − 39°. The 608 MHz emission is shown in white (negative contours shown in green). Contour levels are drawn at ±0.6, 1.2, 2.4 mJy b-1, θ = 50′′ × 50′′. Both images were obtained after subtraction of the discrete sources from the uv data. Right panel: VLA contours at 1377 MHz (θ = 60′′ × 60′′, contours are drawn at ±0.2, 0.4, 0.8, 1.6 mJy b-1) overlaid on the 322 MHz GMRT image. Negative contours are drawn as dashed lines. The green arrow highlights the north-western extension (see Sect. 4.1).
