Lumen modeling of IllustrisTNG50 shows that high ionization parameters from massive star clusters plus enhanced nitrogen abundances are needed to reproduce the extreme [OIII]/Hβ, [OIII]/[OII], and [NII]/Hα ratios seen in z>3 galaxies.

Hybrid hydro/direct N-body simulations of dense high-redshift gas clouds form very massive stars via runaway collisions that collapse to IMBHs capable of growing from ~6700 to ~62000 solar masses in 100 Myr under optimistic assumptions.
JWST observations of lensed galaxies yield tentative evidence for mass- and redshift-dependent radial gradients in nebular dust attenuation, with lower attenuation at higher redshifts and more extended SFR profiles in lower-redshift massive systems consistent with inside-out growth.
