A High Rate of Foreground Contaminants toward High-redshift Galaxies Resolved by JWST

The Astrophysical Journal
We present a study of high-redshift Ly α emitters (LAEs) with multiple components using the Hubble Space Telescope and JWST. High-redshift galaxies are mostly point-like objects on ground-based images, but they often exhibit multiple components in higher

THE LYMAN ALPHA MORPHOLOGY OF LOCAL STARBURST GALAXIES: RELEASE OF CALIBRATED IMAGES [PDF]

The Astronomical Journal, 2009
We present reduced and calibrated high resolution Lyman-alpha (Lya) images for a sample of 6 local star forming galaxies. Targets were selected to represent a range in luminosity and metallicity and to include both known Lya emitters and non-emitters.

SILVERRUSH. XIII. A Catalog of 20,567 Lyα Emitters at z = 2−7 Identified in the Full-depth Data of the Subaru/HSC-SSP and CHORUS Surveys

The Astrophysical Journal Supplement Series, 2023
We present 20,567 Ly α emitters (LAEs) at z = 2.2 − 7.3 that are photometrically identified by the SILVERRUSH program in a large survey area up to 25 deg ^2 with deep images of five broadband filters ( grizy ) and seven narrowband filters targeting Ly α ...

Lyman-alpha absorption around nearby galaxies

, 2002
We have used STIS aboard HST to search for Lyman-alpha (Lya) absorption lines in the outer regions of eight nearby galaxies using background QSOs and AGN as probes. Lya lines are detected within a few hundred km/s of the systemic velocity of the galaxy in all cases.

The Size Evolution and the Size–Mass Relation of Lyα Emitters across 3 ≲ z< 7 as Observed by JWST

The Astrophysical Journal
Understanding the morphological structures of Ly α emitters (LAEs) is crucial for unveiling their formation pathways and the physical origins of Ly α emission. However, the evolution of their sizes and structural scaling relations remains debated.

A Spectral Atlas of Lyα Emitters at z = 5.7 and z = 6.6

The Astrophysical Journal
We present two uniformly observed spectroscopic samples of Ly α emitters (LAEs; 127 at z = 5.7 and 82 at z = 6.6), which we use to investigate the evolution of the LAE population at these redshifts.

The Astrophysical Journal
We present the first results from the Web Epoch of Reionization Ly α Survey (WERLS), a spectroscopic survey of Ly α emission using Keck I/MOSFIRE and LRIS.

LATIS Data Release: ∼4200 Spectra of z ∼ 2–3 Galaxies, Redshifts, and Intergalactic Medium Tomography Maps

The Astrophysical Journal Supplement Series
We present the data release of the Ly α Tomography IMACS Survey (LATIS), one of the largest optical spectroscopic surveys of faint high-redshift galaxies.
