Extended Data Fig. 4: SED modeling for JADES-GS-z14-0.
From: Photometric detection at 7.7 μm of a galaxy beyond redshift 14 with JWST/MIRI
Similar to Fig. 2, the measured spectral flux density and corresponding uncertainties are used to constrain the various SED models with Prospector. As provided in Table 1, the mean and 1σ standard deviation of the fiducial model fitting photometry are the red circles and error bars. The median of the SED models is the gray line and unfilled squares, while the 1σ confidence interval is the shaded region. These results suggest that the excess flux in F770W relative to F444W is from stellar continuum rather than nebular emission line contributions, producing strong Balmer breaks in the models, which we find unlikely given the extreme inferred stellar masses and stellar ages.
