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.

Connecting Lyα and Ionizing Photon Escape in the Sunburst Arc

The Astrophysical Journal
We investigate the Ly α and Lyman continuum (LyC) properties of the Sunburst Arc, a z = 2.37 gravitationally lensed galaxy with a multiply imaged, compact region leaking LyC and a triple-peaked Ly α profile indicating direct Ly α escape.

JWST Unveils the Bimodal Nature of Lyα Emitters at 3 < z < 7: Pristine versus Merger-driven Populations

The Astrophysical Journal
We present a systematic study of merging galaxies among Lyα emitters (LAEs) using James Webb Space Telescope/NIRCam high-resolution imaging data. From a large sample of 817 spectroscopically confirmed LAEs at 3  6 to 70% at z

The Lyα and Continuum Origins Survey. I. Survey Description and Lyα Imaging

The Astrophysical Journal Supplement Series
Understanding the mechanisms driving the escape of ionizing or Lyman continuum (LyC) emission from the interstellar medium of galaxies is necessary to constrain the evolution of reionization and the sources responsible for it.

On the Physical Nature of Lyα Transmission Spikes in High-redshift Quasar Spectra

The Astrophysical Journal
We investigate Lyman-alpha (Ly α ) transmission spikes at 5.2 < z < 6.8 using synthetic quasar spectra from the “Cosmic Reionization on Computers” simulations.

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 ...

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.
