SILVERRUSH. XIV. Lyα Luminosity Functions and Angular Correlation Functions from 20,000 Lyα Emitters at z ∼ 2.2–7.3 from up to 24 deg2 HSC-SSP and CHORUS Surveys: Linking the Postreionization Epoch to the Heart of Reionization

The Astrophysical Journal Supplement Series
We present luminosity functions (LFs) and angular correlation functions (ACFs) derived from 18,960 Ly α emitters (LAEs) at z  = 2.2−7.3 over a wide survey area of ≲24 deg ^2 that are identified in the narrowband data of the HSC-SSP and CHORUS surveys ...

Observing Lyman alpha emitters - How does Lyman alpha escape from galaxies?

, 2016
The Lyman alpha (Lyα) emission line has grown to become one of the most successful tools for finding galaxies at high redshift. At redshifts corresponding to the early cosmic times of reionization and primeval galaxy formation, the wavelength of Lyα is still accessible with ground-based facilities.

ODIN: High Clustering Strength of Protoclusters at Cosmic Noon

The Astrophysical Journal
The One-hundred-deg ^2 DECam Imaging in Narrowbands (ODIN) survey is carrying out a systematic search for protoclusters during Cosmic Noon, using Ly α -emitting galaxies (LAEs) as tracers.

High-resolution Observations of CO(3–2) in Haro 2: Cool Molecular Outflows of a Lyα Emitter

The Astronomical Journal
Haro 2 is a blue compact dwarf galaxy and the closest (at 21 Mpc) known Lyα emitter. UV and optical observations have found Haro 2 to be immersed in shells of partly ionized gas expanding at ∼200 km s ^−1 .

On the origins of oxygen: ALMA and JWST characterise the multi-phase, metal-enriched, star-bursting medium within a 'normal' $z > 11$ galaxy

The Open Journal of Astrophysics
The unexpectedly high abundance of galaxies at $z > 11$ revealed by JWST has sparked a debate on the nature of early galaxies and the physical mechanisms regulating their formation.

An Extremely Metal-poor Lyα Emitter Candidate at z = 6 Revealed through Absorption Spectroscopy

The Astrophysical Journal Letters
We report the discovery of a Ly α emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at z _QSO = 6.0685 at a projected distance ∼29 pkpc that is associated with an extremely metal-poor absorption system.

Bayesian Component Separation for DESI LAE Automated Spectroscopic Redshifts and Photometric Targeting

The Astrophysical Journal
Lyα emitters (LAEs) are valuable high-redshift cosmological probes traditionally identified using specialized narrowband photometric surveys. In ground-based spectroscopy, it can be difficult to distinguish the sharp LAE peak from residual sky emission ...
