ODIN: Clustering Analysis of 14,000 Lyα-emitting Galaxies at z = 2.4, 3.1, and 4.5

The Astrophysical Journal Letters
Ly α emitters (LAEs) are star-forming galaxies that efficiently probe the spatial distribution of galaxies in the high-redshift Universe. The spatial clustering of LAEs reflects the properties of their individual host dark matter halos, allowing us to ...

Mapping the Cosmic Web with Ly-alpha Emission

, 2003
We use a high-resolution cosmological simulation to predict the distribution of HI Ly-alpha emission from the low-redshift (z10^2 kpc) ``coronae'' of optically thin gas with Ly-alpha surface brightness close to the expected background.

Lyα Profile Shape as an Escape-fraction Diagnostic at High Redshift

The Astrophysical Journal
While the shape of the Ly α profile is viewed as one of the best tracers of ionizing-photon escape fraction ( f _esc ) within low-redshift ( z ∼ 0.3) surveys of the Lyman continuum, this connection remains untested at high redshift. Here, we combine deep,

A galaxy as the source of a Civ absorption system close to the epoch of reionization

, 2011
We find a bright (L_{UV}=2.5 L*_{z=6}) Lyman alpha emitter at redshift z=5.719 at a projected distance of 79 physical kpc from a strong triply ionized carbon (Civ) absorption system at redshift z=5.7238 previously reported in the spectrum of the z_{em} =

Effect of Lyα Radiative Transfer on Intensity Mapping Power Spectra

The Astrophysical Journal
Clustering of Ly α -emitting galaxies (LAEs) and Ly α line intensity mapping (LIM) are useful probes of cosmology. However, Ly α radiative transfer (RT) effects, such as absorption, line shift, and line broadening, and their dependence on the large-scale

The Lyα and Continuum Origins Survey. II. The Connection between the Escape of Ionizing Radiation and Lyα Halos in Star-forming Galaxies

The Astrophysical Journal
One of the current challenges in galaxy evolution studies is to establish the mechanisms that govern the escape of ionizing radiation from galaxies.

LATIS: Constraints on the Galaxy–Halo Connection at z ∼ 2.5 from Galaxy–Galaxy and Galaxy–Lyα Clustering

The Astrophysical Journal
The connection between galaxies and dark matter halos is often quantified using the stellar mass–halo mass (SMHM) relation. Optical and near-infrared imaging surveys have led to a broadly consistent picture of the evolving SMHM relation based on ...

The MOSDEF-KCWI Survey: Spectral Properties of Lyα Halos around z ∼ 2 Star-forming Galaxies

The Astrophysical Journal
We present Keck Cosmic Web Imager integral field observations of extended Ly α emission in the circumgalactic medium of 27 typical star-forming galaxies at z ∼ 2, drawn from the Multi-Object Spectrometer for Infra-Red Exploration (MOSFIRE) Deep Evolution
