Claims

C1strongest claim

We find that the observed A_FUV-M_star relation at z > 9 is best reproduced for an intrinsic FUV dust opacity kappa_UV(dust)=1000 cm2/g, characteristic of low-opacity SNe dust, naturally producing very low attenuation even in gas-rich galaxies.

C2weakest assumption

The premise that galaxies at z>9 are dominated by low-opacity SNe-produced dust before efficient ISM grain growth is established, which is invoked to justify the low kappa_UV value and the transition framework.

C3one line summary

A transition to low-opacity supernova-produced dust at z>9 reduces effective UV attenuation in gas-rich galaxies and reproduces the observed UV luminosity function and A_FUV-M_star relation.
