Abstract

We present a new determination of the evolving galaxy UV luminosity function (LF) over the redshift range 8.58.5)>0.05) to undertake a statistical calculation of the UV LF. Our new measurements span ≃4 magnitudes in UV luminosity at z=9-12.5, placing new constraints on both the shape and evolution of the LF at early times. Our measurements yield a new estimate of the early evolution of cosmic star-formation rate density (ρ_\rmSFR) confirming the gradual decline deduced from early JWST studies, at least out to z ≃ 12. Finally we show that the observed early evolution of the galaxy UV LF (and ρ_\rmSFR) can be reproduced in a \rm ΛCDM Universe, with no change in dust properties or star-formation efficiency required out to z ≃ 12. Instead, a progressive trend towards younger stellar population ages can reproduce the observations, and the typical ages required at z ≃ 8, 9, 10, and 11 all converge on ≃ 380-330 Myr after the Big Bang, indicative of a rapid emergence of early galaxies at z ≃ 12 - 13. This is consistent with the first indications of a steeper drop-off in ρ_\rmSFR we find beyond z ≃ 13, possibly reflecting the rapid evolution of the halo mass function at earlier times.
