We study the luminosity functions of high-redshift galaxies in detailed hydrodynamic simulations of cosmic reionization, which are designed to reproduce the evolution of the Lyα forest between z ~ 5 and ~6. We find that the luminosity functions and total stellar mass densities are in agreement with observations when plausible assumptions about reddening at z ~ 6 are made. Our simulations support the conclusion that stars alone reionized the universe. 
Intergalactic baryon-rich regions at high redshift
Using a high-resolution cosmological simulation of reionization, we have examined the differing structures formed by gas and dark matter at a redshift of 5.1. Baryon-rich regions form a small number
Intergalactic filaments as isothermal gas cylinders
Using a cosmological simulation at redshift 5, we find that the baryon-rich cores of intergalactic filaments extending outwards from galaxies commonly form isothermal gas cylinders in regions


Lyman Break Galaxies and Reionization of Universe
We present the star formation histories, luminosities, colors, mass-to-light ratios, and halo masses of "galaxies" formed in a simulation of cosmological reionization. We compare these galaxies with
Lyman break galaxies at z= 4–6 in cosmological smoothed particle hydrodynamics simulations
We perform a spectrophotometric analysis of galaxies at redshifts z = 4-6 in cosmological smoothed particle hydrodynamics simulations of a A cold dark matter universe. Our models include radiative
Radiative Transfer in a Clumpy Universe. III. The Nature of Cosmological Ionizing Sources
The history of the transition from a neutral intergalactic medium (IGM) to one that is almost fully ionized can reveal the character of cosmological ionizing sources. We study the evolution of the
Lyman Break Galaxies at z = 4 - 6 in cosmological SPH Simulations
We perform a spectrophotometric analysis of galaxies at redshifts z = 4 - 6 in cosmological SPH simulations of a Lambda CDM universe. Our models include radiative cooling and heating by a uniform UV
Hierarchical galaxy formation
We describe the GALFORM semi-analytic model for calculating the formation and evolution of galaxies in hierarchical clustering cosmologies. It improves upon, and extends, the earlier scheme developed
The physical and photometric properties of high-redshift galaxies in cosmological hydrodynamic simulations
We study the physical and photometric properties of galaxies at z = 4 in cosmological hydrodynamic simulations of a ΛCDM universe. We focus on galaxies satisfying the ``B dropout" criteria of the
The Stellar Mass Function of Galaxies to z ~ 5 in the FORS Deep and GOODS-South Fields
We present a measurement of the evolution of the stellar mass function (MF) of galaxies and the evolution of the total stellar mass density at 0 1010 M☉, which are the likely progenitors of today's L
Cosmic Reionization Redux
We show that numerical simulations of reionization that resolve the Lyman limit systems (and, thus, correctly count absorptions of ionizing photons) have converged to about a 10% level for 5 < z <
The Evolution of the Intergalactic Medium Transmission to Redshift 6
We have measured the transmission of the Lyα forest produced by neutral hydrogen scattering in the intergalactic medium between redshifts 2 and 6.3 using high signal-to-noise, high-resolution (R ≥
Specific star formation rates to redshift 5 from the fors deep field and the GOODS-S field
We explore the buildup of stellar mass in galaxies over the wide redshift range 0.4 < z < 5.0 by studying the evolution of the specific star formation rate (SSFR), defined as the star formation rate
