a,b: Rest-frame UV spectrum of Godzilla from Magellan/MagE (Rigby et al. in prep.), showing the O I triplet and Si II line complex around 1304 Å and O I] 1641 Å. All these O I lines are part of the Lyβ pumped Bowen fluorescence cascade. c: NIRSpec spectrum showing position of the rest-frame optical O I recombination lines and/or stellar continuum excitation cascade triplet around 7776 Å and line complex at around 7990 Å, where we would expect to see line emission if the observed O I cascade were due to recombination or stellar continuum pumping. d: Lyβ-pumped, Bowen fluorescent O I 8449 Å.
