Abstract The Epoch of Reionization (EoR) represents a milestone in the evolution of our Universe. Star-forming galaxies that existed during the EoR likely emitted a significant fraction ( ~ 5 − 40%) of their bolometric luminosity as Lyα line emission. However, neutral intergalactic gas that existed during the EoR was opaque to Lyα emission that escaped from galaxies during this epoch, which makes it difficult to observe. The neutral intergalactic medium (IGM) may thus reveal itself by… 
Ly α emission from galaxies in the Epoch of Reionization
The intrinsic strength of the Lyα line in young, star-forming systems makes it a special tool for studying high-redshift galaxies. However, interpreting observations remains challenging due to the
Can Galaxy Evolution Mimic Cosmic Reionization?
Lyα emitting galaxies are powerful tools to probe the late stages of cosmic reionization. The observed sudden drop in Lyα fraction at z > 6 is often interpreted as a sign of reionization, since the
Constraining Reionization with Ly α Emitting Galaxies
Neutral diffuse intergalactic gas that existed during the Epoch of Reionization (EoR) suppresses Lyα flux emitted by background galaxies. In this chapter I summarise the increasing observational
Lyman α-emitting galaxies in the epoch of reionization
With a total integration time of 168 h and a narrowband filter tuned to Lyα emission from z = 8.8, the UltraVISTA survey has set out to find some of the most distant galaxies, on the verge of the
Ly-α and Mg II as probes of galaxies and their environment
Lyα emission, Lyα absorption, and Mg ii absorption are powerful tracers of neutral hydrogen. Hydrogen is the most abundant element in the universe and plays a central role in galaxy formation via gas
The Origin and Evolution of Lyα Blobs in Cosmological Galaxy Formation Simulations
High-redshift Lyα blobs (LABs) are an enigmatic class of objects that have been the subject of numerous observational and theoretical investigations. It is of particular interest to determine the

Abstract The Lyman alpha emission line (Lyα) of neutral hydrogen (Hi) is intrinsically the brightest emission feature in the spectrum of astrophysical nebulae, making it a very attractive
Lyα-emitting galaxies as a probe of reionization: large-scale bubble morphology and small-scale absorbers
The visibility of LyA emitting galaxies during the Epoch of Reionization is controlled by both diffuse HI patches in large-scale bubble morphology and small-scale absorbers. To investigate the impact
A Systematic Study of the Escape of LyC and Lyα Photons from Star-forming, Magnetized Turbulent Clouds
Understanding the escape of Lyman continuum (LyC) and Lyα photons from giant molecular clouds (GMCs) is crucial if we are to study the reionization of the universe and to interpret spectra of
Scattering of Lyα Photons through the Reionizing Intergalactic Medium: I. Spectral Energy Distribution
During reionization, a fraction of galactic Lyα emission is scattered in the intergalactic medium (IGM) and appears as diffuse light extending megaparsecs from the source. We investigate how to probe


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 effects of reionization on Lyα galaxy surveys
Searches for Lya emission lines are among the most effective ways to identify high-redshift galaxies. They are particularly interesting because they probe not only the galaxies themselves but also
Mapping Neutral Hydrogen during Reionization with the Lyα Emission from Quasar Ionization Fronts
We present a new method to directly map the neutral-hydrogen distribution during the reionization epoch and constrain the emission properties of the highest redshift quasars (QSOs). As a tracer of H
Models for Dusty Lyα Emitters at High Redshift
Models are presented for the Lyα emission of dusty high-redshift galaxies by combining the Press-Schechter formalism with a treatment of the inhomogeneous dust distribution inside galaxies. It is
Seeing through the trough: outflows and the detectability of Lyα emission from the first galaxies
The next generation of telescopes aim to directly observe the first generation of galaxies that initiated the reionization process in our Universe. The Lyα emission line is robustly predicted to be
Scattered Lyα Radiation around Sources before Cosmological Reionization
The spectra of the first galaxies and quasars in the universe should be strongly absorbed shortward of their rest-frame Lyα wavelength by neutral hydrogen (H I) in the intervening intergalactic
The visibility of Lyman α emitters during reionization
We present the first Lyman α emitter (LAE) study that combines: (i) cosmological smoothed particle hydrodynamic (SPH) simulations run using GADGET-2, (ii) radiative transfer simulations (CRASH) and
The Detectability of High-Redshift Lyα Emission Lines prior to the Reionization of the Universe
For a source of Lyα radiation embedded in a neutral intergalactic medium (IGM) prior to the reionization epoch, the Lyα emission line is strongly suppressed by the intervening IGM. The damping wing

Context: Lyman-alpha (Lyα) radiation is now widely used to investigate the galaxy formation and evolution in the high redshift universe. However, without a rigorous understanding of the processes
Intergalactic Transmission and Its Impact on the Lyα Line
We study the intergalactic transmission of radiation in the vicinity of the Ly{\alpha} wavelength. Simulating sightlines through the intergalactic medium (IGM) in detailed cosmological
