Popis:
We present the census of H$\beta$+[O III] $4960,5008$ \AA emitters at $6.87$ galaxies. We report a rapid decline of the [O III] luminosity density at $z\gtrsim 6-7$ which cannot be explained solely by the evolution of the cosmic star-formation rate density. Finally, we find that FRESCO, in only $2$h, captures star-forming galaxies likely accounting for $\sim 10-20\%$ of the ionising budget at $z=7$ and $z=8$, raising the prospect of detecting directly all the sources of reionisation with JWST.
