Example spectra showing the PRISM (left) and G140M grating zoom-in on Lyα emission (right) of faint LAEs selected from the Deep Tier spectra in JADES, with 1σ noise shown as green shaded region. The Lyα line sensitivity in the G140M spectra is considerably higher compared to PRISM, where the decreasing spectral resolution at bluer wavelengths results in diminished emission line sensitivity. Therefore, a combination of both PRISM and Grating spectra is key to identifying Lyα emission.
