Best fit on the SED and the inferred attenuation curves of three galaxies at the EoR. The left panels show the NIRSpec JWST spectrum of s00717 (top), s01143 (middle), and s01149 (bottom) in blue, with flux uncertainties illustrated in pale blue. Orange and pale orange colors indicate the best-fit posterior spectrum with 1σ uncertainties, respectively. Vertical dashed lines mark the prominent detected emission lines and positions of potential lines present in the spectra. In the bottom panel of each plot, we show the residuals of the best fit on the observed spectra, Δf_λ, with 1σ uncertainties. The right panels depict the best-fit dust attenuation curves with 1σ uncertainties for s00717, s01143, and s01149 sources, which were obtained using the SED fitting method with the non-parametric SFH model. Drude model fits to the Calzetti, the MW, the SMC, and the LMC empirical curves are shown as green, red, purple, and brown dashed lines, respectively.
