Top: RGB image of gravitational lens system DESI J003.6745–13.5042 observed with MUSE. The image is a combination of the Johnson V (yellow), Cousins R (magenta), and Cousins I (cyan) images generated from the MUSE data cube. The white square indicates the cutout shown in the right panel. Bottom: MUSE spectra of DESI J003.6745–13.5042 in rest-frame wavelength, with the host galaxy above and the lensed source below. Redshifts are written at the top of each panel, and in the lower panels, the emission and absorption lines are shown in more detail. For more information on the system, see Description 1.
