Top: zoom-in on the foreground z ∼ 0.35 galaxy located to the southeast of SPARCS1049+56 and labeled S3 in Figure 3. (a) Composite HST image (F105W in blue and green; F160W in red), highlighting foreground galaxies, including S3. (b) 144 MHz LOFAR low-resolution image with a beam size of 6﹩\mathop{.}\limits^{\unicode{x02033}}﹩0 by 6﹩\mathop{.}\limits^{\unicode{x02033}}﹩0, where contours are 4σ_rms, 6σ_rms, 8σ_rms, and 10σ_rms and σ_rms = 33 μJy beam⁻¹. (c) JVLA 1.5 GHz image from A. Trudeau et al. (2019), with contours at 3σ_rms, 4σ_rms, and 5σ_rms, where σ_rms = 10.5 μJy beam⁻¹. (d) JVLA 6 GHz image from A. Trudeau et al. (2019), with contours at 3σ_rms, 4σ_rms, and 5σ_rms, where σ_rms = 3 μJy beam⁻¹. Although LOFAR looks like a one-sided jet, the combined JVLA and HST images show that the radio emission originates from multiple foreground galaxies and their associated AGN. Bottom: same as the top row, but zoomed-in on the source S4 and the source S7? from Figure 3. Color bars are included; radio image units are Jy beam⁻¹.
