Model predictions for GS-z14-0. Top panel: temperature distribution as a function of the dust spatial distribution radius, r_d, in units of the effective stellar radius of GS-z14-0, r_e = 260 pc. The different orange curves span the range of the dust-to-stellar ratio −5 < log ξ_d < −1.6, equally spaced in 0.1 logarithmic intervals. The black curve highlights the fiducial case log ξ_d = −2.72(ξ_d = 1/529). We also show the CMB temperature at the galaxy redshift z = 14.32. The circles indicate the radius for which A_V of the galaxy matches the observed radius, A_V = 0.31. Bottom panel: as in the top panel, but for the predicted observed flux from GS-z14-0 at 88 μ. We also show the expected 3σ sensitivity limit (18 μJy/beam) and the spatial resolution (0.418″) of the DDT 2023.A.00037.S (PI: S. Schouws) observations.
