Recent observations have shown that the characteristic luminosity of the rest-frame ultraviolet (UV) luminosity function does not significantly evolve at 4 < z < 7 and is approximately M UV ∼ −21. We investigate this apparent non-evolution by examining a sample of 178 bright, MUV < −21 galaxies at z = 4 to 7, analyzing their stellar populations and host halo masses. Including deep Spitzer/IRAC imaging to constrain the rest-frame optical light, we find that M UV galaxies at z = 4–7 have similar…

A massive, quiescent galaxy at a redshift of 3.717
TLDR
Spectroscopic confirmation of a massive, quiescent galaxy at redshift z = 3.717 demonstrates that the galaxy must have formed the majority of its stars quickly, within the first billion years of cosmic history in a short, extreme starburst.
The Quest for Dusty Star-forming Galaxies at High Redshift z>4
We exploit the continuity equation approach and the `main sequence' star-formation timescales to show that the observed high abundance of galaxies with stellar masses > a few 10^10 M_sun at redshift
Simulating galaxies in the reionization era with FIRE-2: galaxy scaling relations, stellar mass functions, and luminosity functions
We present a suite of cosmological zoom-in simulations at z>5 from the Feedback In Realistic Environments project, spanning a halo mass range M_halo~10^8-10^12 M_sun at z=5. We predict the stellar
Evidence for Reduced Specific Star Formation Rates in the Centers of Massive Galaxies at z = 4
We perform the first spatially-resolved stellar population study of galaxies in the early universe (z = 3.5 - 6.5), utilizing the Hubble Space Telescope Cosmic Assembly Near-infrared Deep
Constraints on the star formation efficiency of galaxies during the epoch of reionization
Reionization is thought to have occurred in the redshift range of 6 6 that matches the measured galaxy luminosity functions at these redshifts. We find that f⋆ peaks at ∼30 per cent at halo masses M
The Galaxy UV Luminosity Function Before the Epoch of Reionization
We present a model for the evolution of the galaxy ultraviolet (UV) luminosity function (LF) across cosmic time where star formation is linked to the assembly of dark matter halos under the
Interpreting the evolution of galaxy colours from z = 8 to 5
We attempt to interpret existing data on the evolution of the UV luminosity function and UV colours, β, of galaxies at 5 ≤ z ≤ 8, to improve our understanding of their dust content and interstellar
UniverseMachine: The correlation between galaxy growth and dark matter halo assembly from z = 0−10
We present a method to flexibly and self-consistently determine individual galaxies’ star formation rates (SFRs) from their host haloes’ potential well depths, assembly histories, and redshifts. The
The Impossibly Early Galaxy Problem
The current hierarchical merging paradigm and $\Lambda$CDM predict that the $z \sim 4-8$ universe should be a time in which the most massive galaxies are transitioning from their initial halo
Introducing the FirstLight project: UV luminosity function and scaling relations of primeval galaxies
We introduce the FirstLight project that aims to generate a large database of high-resolution, zoom-in simulations of galaxy formation around the epoch of reionisation ($z\geq6$). The first results

A dusty, normal galaxy in the epoch of reionization
TLDR
Thermal dust emission from an archetypal early Universe star-forming galaxy, A1689-zD1, is reported, which has a large stellar mass and is heavily enriched in dust, with a dust-to-gas ratio close to that of the Milky Way.

Galaxies at redshifts 5 to 6 with systematically low dust content and high [C ii] emission
TLDR
It is found that nine typical star-forming galaxies about one billion years after the Big Bang have thermal emission that is less than 1/12 that of similar systems about two billion years later, and enhanced [C ii] emission relative to the far-infrared continuum, confirming a strong evolution in the properties of the interstellar medium in the early Universe.
