The evolution of [OIII]+\rm{H}β equivalent width from \mathbf{z\simeq3-8}: implications for the production and escape of ionizing photons during reionization

Accurately quantifying the ionizing photon production efficiency (\xi_\rm{ion}) of z>6 star-forming galaxies (SFGs) is necessary to understand their contribution to reionization. We investigate the ionizing properties of N=289 SFGs selected at z=6.9-7.6 from the JWST Cycle-1 imaging programmes; PRIMER and JADES. We use BAGPIPES to consistently infer the equivalent widths...
