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 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.

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

Observational Signatures of Lyman Alpha Emission from Early Galaxy Formation

, 2011
The next generation of telescopes aim to directly observe the first generation of galaxies that initiated the reionization process in our Universe. The Lyman Alpha (Lya) emission line is robustly predicted to be the most prominent intrinsic spectral ...

Cosmic Himalayas: The Highest Quasar Density Peak Identified in a 10,000 deg2 Sky with Spatial Discrepancies between Galaxies, Quasars, and IGM H i

The Astrophysical Journal
We report the identification of a quasar overdensity in the BOSSJ0210 field, dubbed the Cosmic Himalayas, consisting of 11 quasars at z = 2.16−2.20, the densest overdensity of quasars (17 σ ) in the ∼10,000 deg ^2 of the Sloan Digital Sky Survey (SDSS ...

MUSEQuBES: Connecting H i Absorption with Lyα Emitters at z ≈ 3.3

The Astrophysical Journal
We present a comprehensive analysis of H i absorption around 96 Ly α emitters (LAEs) at z  ≈ 3.3 (median Ly α luminosity ≈10 ^42 erg s ^−1 ). These LAEs were identified within eight MUSE fields, each $1^{\prime} \times 1^{\prime} $ on the sky and ...

ODIN: Star Formation Histories Reveal Formative Starbursts Experienced by Lyα-emitting Galaxies at Cosmic Noon

The Astrophysical Journal Letters
In this work, we test the frequent assumption that Ly α -emitting galaxies (LAEs) are experiencing their first major burst of star formation at the time of observation.
