MGCLS full-resolution (7.9″ × 7.5″; yellow) and filtered 25″ resolution (blue) Stokes-I intensity image of MCXC J0351.1−8212, showing newly detected candidate mini-halo and relic-like structures near the cluster centre. The corresponding synthesised beams are shown on the upper left. The colour scale is in square root scaling between 10−500 μJy beam⁻¹ (yellow) and 50−800 μJy beam⁻¹ (blue). Smoothed archival Chandra 0.5−7 keV X-ray contours (levels: 7, 12, 17, 22 × 10⁻⁸ counts cm⁻² s⁻¹) are overlaid in white. The physical scale at the cluster redshift is indicated on the lower left, and the red × marks the NED catalogue position. Inset: DSS r-band image of the dashed region in the main figure, with 15″ resolution MGCLS contours overlaid. Contours start at 3σ = 30 μJy beam⁻¹ and increase in factors of 3.
