Surface brightness and spectral index profiles for the head-tail radio galaxy. Upper panel: Surface brightness trends along the head-tail measured from low-resolution images of the LOFAR at 144 MHz, followed by the uGMRT at 400 MHz, and the uGMRT at 650 MHz. Bottom panel: Spectral index profiles of low-resolution images of low and high frequency, over region numbers and projected distance along the tail in kiloparsecs. Distances in kiloparsecs were calculated, starting from region 0. The flux density for both plots was extracted from circular regions, as is depicted in Fig. 6. The vertical dashed blue line in both plots denotes the location of the arc-shaped cold front, where the tail ‘breaks’, as can be seen in Fig. 1.
