Low resolution LOFAR 144 MHz (Osinga et al. in prep), uGMRT (300–950 MHz), and VLA L-band images of Abell 2256 in square root scale. All images are created at a common 20″ resolution. The radio surface brightness unit is mJy beam⁻¹. The beam size is indicated in the bottom left corner of each image. Contour levels are drawn at [1, 2, 4, 8, …]  ×  3.0 σ_rms, where σ_{144 MHz, rms} = 180μJy beam⁻¹, σ_{350 MHz, rms} = 44μJy beam⁻¹, σ_{675 MHz, rms} = 18μJy beam⁻¹ and σ_{1.5 GHz, rms} = 10μJy beam⁻¹. These images highlights the morphology of the halo emission with observing frequency and show that the halo is much more extended toward low frequencies. There are two other distinct features: an arc-shaped wedge to the east (show within red dotted curves) and source AI to the southwest.
