NIRSpec/PRISM spectrum of JADES-GS-z7-LA (excluding the Lyα region) with the best-fitting spectrum from BAGPIPES. We fit the entire spectrum, but only highlight the strongest emission lines in the figure that have the most constraining power. The fits to the observed emission lines suggest that a high ionization parameter, log(U) = − 0.72 ± 0.14 and low metallicities of Z_burst = 0.31 ± 0.26 Z_⊙ are needed to explain the observed emission lines. The best-fit SED also favors a bursty star formation history (see text). The constraints derived from fitting the spectrum are useful to then fit the photometry of the galaxy as well, as shown in Fig. 7.
