Evolution of galaxy attenuation curves driven by evolving dust mass and grain size distributions

[2508.21157] Evolution of galaxy attenuation curves driven by evolving dust mass and grain size distributions Skip to main content We gratefully acknowledge support from the Simons Foundation, member institutions , and all contributors.
The simulation was carried out with GADGET4-OSAKA, which models the evolution of grain size distributions.
These results may help interpret flatter attenuation curves and weaker bumps in high-redshift galaxies.
Additional contributions come from variations in grain size distribution and the fraction of obscured young stars.
