JWST NIRSpec rest-frame optical spectra of LAE1 and LAE2 in the two gratings/filters used (G235H/F170LP and G395H/F290LP, blue and red lines, respectively), extracted from apertures of R = 0.6″ and 0.3″, respectively. The errors in the spectra are shown in light grey and the kinematic components used to model the emission lines in LAE1 are marked with different curve styles and colours (the two main narrow components are shown with a dashed black and a dotted purple line, respectively, while the broad component is marked shown with a dashed grey line). The spikes that appear in the Hβ emission line of LAE1 are instrumental artefacts; therefore, the measurements of this emission line in LAE1 are not completely reliable.
