Subaru archival ɡ−, r−, and i− (or ɡ, i, and z for NGC 1259 as the r-band image had artifacts) band color images obtained from the Hyper Suprime-Cam (HSC) Legacy Archive (Tanaka et al. 2021). Radio emission is overlaid in red from the 7″ resolution LOFAR image. Red contours are drawn at levels of [1, 2, 4, 8] × 4σ_rms and are from the same image, except for NGC 1259, for which we used the 26″ resolution image.
