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.

New high-redshift empirical T_e-based metallicity calibrations for strong-line ratios derived from direct oxygen abundances in 46 galaxies spanning z=1.4-8.7.
New spectroscopy and simulations of Arp 143 suggest it formed via head-on collision between S0 and Sc galaxies following a flyby.
