The redshift evolution of massive (﹩{\mathrm{log}}_{10}({M}_{\star }/{M}_{\odot })﹩ > 10) galaxies in CEERS. The black solid (dotted) line shows the volume density for ﹩{\mathrm{log}}_{10}({M}_{\star }/{M}_{\odot })﹩ > 10 galaxies exclusive (inclusive) of EROs, with the darker (lighter) shaded region showing the 68% confidence interval (CI) inclusive of sampling the redshift and stellar mass posteriors as well as the Poisson error; the error bars show the error from cosmic variance. We show a variety of pre-JWST results (green–blue points) and a comparison to the massive galaxies presented in Labbé et al. (2023), all converted to a Chabrier IMF. The orange–red curves show the expected cumulative number densities above our mass threshold for a given baryon conversion efficiency (ϵ) calculated using the Rodríguez-Puebla et al. (2016) halo mass function. Our results are systematically higher than previous studies though often within the uncertainties, while following a similar evolution to higher redshifts (details in Section 5) We find that the volume density of massive galaxies follows that expected given a constant baryon conversion efficiency of ϵ ∼ 0.14 up to z ∼ 5, before which the volume densities begin to exceed the predicted values.
