HST imaging of the host galaxy of FRB 20201124A in filters F160W (left; IR) and F475X (right; optical) showing a barred spiral morphology. All panels are 6″ × 6″. The host center is denoted as a yellow cross, and the FRB EVN position is marked as a red star. Radio contours at 6 GHz are overlaid at −2σ (dotted, gray), 2σ (dark blue), 4σ (light blue), and 6σ (white) significance in the bottom panels. Contours for the elongated radio emission at 22 GHz as observed by Piro et al. (2021) are shown at −2σ, 2σ, and 4σ significance in magenta.
