Left: LOFAR 145 MHz high-resolution image (7.5 arcmin × 7.5 arcmin) of the cluster system eFEDS J093513.3+004746 and eFEDS J093510.7+004910. The LOFAR (yellow) and uGMRT (cyan) contours are drawn at levels of [1, 2, 4, 8, 16, 32, 64] × 3σ where σ_LOFAR = 265 μJy beam⁻¹ and σ_uGMRT = 45 μJy beam⁻¹. The resolution is 14.7 arcsec × 7.0 arcsec with a position angle of −85 degree and 6.9 arcsec × 5.1 arcsec (PA = 57 degree) for the LOFAR and uGMRT images, respectively. The X-ray eROSITA (white) contours are at the levels of [0.2, 0.36, 0.52, 0.68, 0.84, 1] cts s⁻¹ arcmin⁻². Right: LOFAR 145 MHz and uGMRT 383 MHz low-resolution contour image after the subtraction of pointsources which are shown with the white and blue lines, respectively. The LOFAR (yellow) and uGMRT (cyan) contour levels are identical to those in the left image with σ_LOFAR = 340 μJy beam⁻¹ and σ_uGMRT = 70 μJy beam⁻¹. Here beam_LOFAR = 19.8 arcsec × 16.2 arcsec (PA = 66 degree) and beam_uGMRT = 15.5 arcsec × 13.9 arcsec (PA = 75 degree). The (magenta dashed) ellipse shows the region where the integrated flux density for radio halo is measured. In both images, the LOFAR and uGMRT synthesized beams are shown in the bottom left and right corners, respectively.
