Composite RGB image of A2142: radio (LOFAR at 143 MHz, 9″ × 6″) in red, optical (DSS-2, r-filter) in green, and X-rays (XMM-Newton, 0.7–1.2 keV) in blue. Labels indicate the tailed radio galaxies (T1, T2), the primary and secondary brightest cluster galaxies (BCG1, BCG2), and the two components (H1, H2) of the radio halo. The dashed white contours represent the 3σ level of the 73″ × 66″ LOFAR image at 143 MHz reported in Bruno et al. (2023), showing the third component (H3) of the radio halo. The yellow arrows indicate the location of the NW, central, and SE cold fronts reported by Rossetti et al. (2013).
