Rest-frame UV emission lines of A2744-45924. The left column shows the 1D spectrum around the wavelength of selected UV emission lines: N IV] (λλ1483,1486), C IV (λλ1548,1551), He II (λ1640), and O III] (λλ1661,1666). In the case of N IV] and O III] the best-fitting two-component Gaussian model with fixed width is also shown. The right column shows images obtained collapsing the MUSE datacube in an interval of 10 Åcentered on the selected lines (for doublets, both components stacked), and subtracting the continuum, measured 1000 Åaround the position of the line (masking other emission lines and skylines).
