New JWST spectrum of a z=8.3 galaxy with prior ALMA dust detection shows AGN signatures, 0.15 Zsun metallicity, Mdust ~10^6 Msun, Tdust~91 K, and an [OIII] line ratio higher than nebular models allow.

Setting the cold neutral medium density to 7500 cm^{-3} in a model for MACS0416_Y1 allows UV trapping and reduced supernova destruction, reproducing the UV-to-FIR SED with intermediate-size grains dominating the infrared output.

DREAMS. JWST Spectroscopy of a $z=8.3$ Galaxy with an ALMA Dust Continuum Detection: Early Dust, Very High $T_{\rm dust}$, and a Multi-wavelength [OIII] Ratio Discrepancy
New JWST spectrum of a z=8.3 galaxy with prior ALMA dust detection shows AGN signatures, 0.15 Zsun metallicity, Mdust ~10^6 Msun, Tdust~91 K, and an [OIII] line ratio higher than nebular models allow.

Resolving the Dust Budget Crisis at $z \sim 8$ with Optically Thick, High-Density Molecular Clumps: MACS0416_Y1
Setting the cold neutral medium density to 7500 cm^{-3} in a model for MACS0416_Y1 allows UV trapping and reduced supernova destruction, reproducing the UV-to-FIR SED with intermediate-size grains dominating the infrared output.
