Recent observations have constrained the galaxy UV luminosity function up to z~10. However, these observations alone allow for a wide range of reionization scenarios due to uncertainties in the abundance of faint galaxies and the escape fraction of ionizing photons. We show that requiring continuity with post-reionization (z ~10 from z=4 (where the best fit is 4%) to z=9; or 3) more likely, a hybrid solution in which undetected galaxies contribute significantly and f_esc increases more modestly… 
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 redshift evolution of escape fraction of hydrogen ionizing photons from galaxies
Using our cosmological radiative transfer code, we study the implications of the updated QSO emissivity and star formation history for the escape fraction (f_esc) of hydrogen ionizing photons from
Effect of Halo Bias and Lyman Limit Systems on the History of Cosmic Reionization
We extend the existing analytical model of reionization by Furlanetto et?al. to include the biasing of reionization sources and additional absorption by Lyman limit systems. Both effects enhance the
The escape fraction of ionizing photons from high-redshift galaxies from data-constrained reionization models
The escape fraction, fesc, of ionizing photons from high-redshift galaxies is a key parameter to understand cosmic reionization and star formation history. Yet, in spite of many efforts, it remains
A minimalist feedback-regulated model for galaxy formation during the epoch of reionization
Near-infrared surveys have now determined the luminosity functions of galaxies at 6 ≲ z ≲ 8 to impressive precision and identified a number of candidates at even earlier times. Here, we develop a
Cosmic Reionization after Planck: Could Quasars Do It All?
We assess a model of late cosmic reionization in which the ionizing background radiation arises entirely from high redshift quasars and other active galactic nuclei (AGNs). The low optical depth to
The little Galaxies that could (reionize the universe): predicting faint end slopes & escape fractions at z>4
The sources that reionized the universe are still unknown, but likely candidates are faint but numerous galaxies. In this paper we present results from running a high resolution, uniform volume
Modelling reionization in a bursty universe
We present semi-analytic models of the epoch of reionization focusing on the differences between continuous and bursty star formation (SF). Our model utilizes physically motivated analytic fits to 1D
Evolution in the escape fraction of ionizing photons and the decline in strong Lyα emission from z > 6 galaxies
The rapid decline in the number of strong Lyman Alpha (Lya) emitting galaxies at z > 6 provides evidence for neutral hydrogen in the IGM, but is difficult to explain with plausible models for
Conditions for Reionizing the Universe with a Low Galaxy Ionizing Photon Escape Fraction
We explore scenarios for reionizing the intergalactic medium with low galaxy ionizing photon escape fractions. We combine simulation-based halo-mass dependent escape fractions with an extrapolation


The detectability of Lyα emission from galaxies during the epoch of reionization
We study the visibility of the Lyα emission line during the epoch of reionization. Combining galactic outflow models with large-scale seminumeric simulations of reionization, we quantify the
The Galaxy Luminosity Function during the Reionization Epoch
The new Wide Field Camera 3/IR observations on the Hubble Ultra-Deep Field started investigating the properties of galaxies during the reionization epoch. To interpret these observations, we present
On the Kennicutt-Schmidt relation of low-metallicity high-redshift galaxies
We present results of self-consistent, high-resolution cosmological simulations of galaxy formation at z~3. The simulations employ recently developed recipe for star formation based on the local
One of the main challenges facing standard hierarchical structure formation models is that the predicted abundance of Galactic subhalos with circular velocities vc ~ 10-30 km s-1 is an order of
Escape fraction of ionizing photons from high-redshift galaxies in cosmological SPH simulations
Combing the three-dimensional radiative transfer (RT) calculation and cosmological smoothed particle hydrodynamics (SPH) simulations, we study the escape fraction of ionizing photons (f esc ) of

An Ionizing Ultraviolet Background Dominated by Massive Stars
We discuss the implications of a stellar-dominated UV background at high redshifts for the star formation history of Lyman break galaxies (LBGs) and the thermal and ionization state of the
It has been argued that low-luminosity dwarf galaxies are the dominant source of ionizing radiation during cosmological reionization. The fraction of ionizing radiation that escapes into the
