Radio, X-ray, and optical images of the centre region of A3017. Top-left: Zoomed-in full-resolution MeerKAT 1280 MHz image with contour levels of [1, 2, 4, 8] × 5σ. Negative −3σ contours are shown with dotted lines. Top-right: Chandra 0.5–7.0 keV exposure-corrected image, overlaid with the same contours as in the top-left panel. The red contours represent a pair of X-ray cavities outlined by utilising the CAvity DEtection Tool (CADET; Plšek et al. 2024). An inner X-ray surface brightness edge induced by gas sloshing is also marked. Bottom-left: Chandra 0.5–7.0 keV unsharp-masked image, created by subtracting an image smoothed with a 2D Gaussian of 20 pixels from an image smoothed with a 2D Gaussian of 5 pixels. White contours refer to the MeerKAT image of the discrete sources obtained by setting an inner uv-cut of 3437λ (corresponding to ∼1′ or 213 kpc) and show 5σ, 10σ, 20σ, and 40σ intensity levels (σ = 7.55 × 10⁻⁶ Jy beam⁻¹). Right: Composite DECalS optical image using g-, r-, and z-band data, overlaid with the same contours as in the bottom-left panel.
