Predicted continuum flux density at the rest-frame wavelength 88 μm as a function of dust temperature and dust mass. The red line shows the 3σ sensitivity of the DDT ALMA program of JADES-GS-z14-0. The top axis shows the dust-to-stellar mass ratio for the stellar mass of JADES-GS-z14-0 (M_star = 10^8.6 M_⊙). The vertical dashed line shows the expected dust-to-stellar mass ratio for the supernova dust enrichment mechanism, and black circles illustrate the current measurements in galaxies at z>7. The CMB temperature at z = 14 is 41.7 K (dashed region).
