ODIN: Identifying Protoclusters and Cosmic Filaments Traced by Lyα-emitting Galaxies

The Astrophysical Journal
To understand the formation and evolution of massive cosmic structures, studying them at high redshift, in the epoch when they formed the majority of their mass, is essential.

Probing high-redshift galaxies with Ly$\alpha$ intensity mapping

, 2015
We present a study of the cosmological Ly$\alpha$ emission signal at $z > 4$. Our goal is to predict the power spectrum of the spatial fluctuations that could be observed by an intensity mapping survey.

MUSEQuBES: Unveiling Cosmic Web Filaments at z ≈ 3.6 through Dual Absorption and Emission Line Analysis

The Astrophysical Journal Letters
According to modern cosmological models, galaxies are embedded within cosmic filaments, which supply a continuous flow of pristine gas, fueling star formation and driving their evolution. However, due to their low density, the direct detection of diffuse

A Massive H i-absorption-selected Galaxy at z ≈ 2.356

The Astrophysical Journal Letters
We use the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array to detect CO(1–0), CO(3–2), and rest-frame 349 GHz continuum emission from an H i -selected galaxy, DLA1020+2733g, at z  ≈ 2.3568 in the field of the z =

Lyman alpha Emitting Galaxies in the Nearby Universe

, 2015
The Lya emission line of HI is intrinsically the brightest feature in the spectrum of astrophysical nebulae, making it a very attractive observational tool with which to survey galaxies.

Lyα Emission Line Profiles of Extreme [O iii]- emitting Galaxies at z ≳ 2: Implications for Lyα Visibility in the Reionization Era

The Astrophysical Journal
JWST observations have recently begun delivering the first samples of Ly α velocity profile measurements at z > 6, opening a new window into the reionization process.
