False-colour image of the lens systems WGD 2038−4008. This RGB image is created from the F160W (red), F814W (green), and F475X (blue) filters of the HST WFC3. We adjusted the relative amplitudes between the three filters to achieve a higher contrast for better visualization. The four lensed quasar images are marked as A, B, C, and D.
