UV/optical attenuation underpredicts IR luminosity by 3-10x across 0<z<7 while κ_UV/κ_FIR falls by over an order of magnitude, pointing to evolving dust grain properties in average galaxies.

Lyα radiation pressure mildly reduces gas-to-star conversion efficiency in dense high-redshift clusters while dominating the launch of rapid outflows.
A transition to low-opacity SNe-produced dust at z>9 reproduces the observed low attenuation and UV luminosity function excess in early galaxies.
Coevolving super-Eddington black holes and nuclear starbursts in high-redshift halos naturally generate the V-shaped UV-to-optical spectra and weak high-energy emission of little red dots.
Most dusty early-type galaxies exhibit recent star formation components in their stellar populations, as revealed by spectral fitting of 15 nearby examples with a non-dusty control comparison.
