Lyman-alpha Cooling Emission from Galaxy Formation

, 2010
Recent studies have shown that galaxies accrete most of their baryons via the cold mode, from streams with temperatures T~10^4-10^5 K. At these temperatures, the streams should radiate primarily in the Lya line and have therefore been proposed as a model to power the extended, high-redshift objects known as Lya blobs and other high-redshift Lya sources.

MIDIS: JWST NIRCam and MIRI Unveil the Stellar Population Properties of Lyα Emitters and Lyman-break Galaxies at z ≃ 3–7

The Astrophysical Journal
We study the stellar population properties of 182 spectroscopically confirmed (MUSE/VLT) Ly α emitters (LAEs) and 450 photometrically selected Lyman-break galaxies (LBGs) at z = 2.8–6.7 in the Hubble Extreme Deep Field.

Models for Dusty Lyman alpha Emitters at High Redshift

, 1998
Models are presented for the Lyman alpha emission of dusty high-redshift galaxies by combining the Press-Schechter formalism with a treatment of the inhomogeneous dust distribution inside galaxies.

Discovery of a very Lyman-$\alpha$-luminous quasar at z=6.62

, 2017
Distant luminous quasars provide important information on the growth of the first supermassive black holes, their host galaxies and the epoch of reionization.

Understanding the redshift evolution of the luminosity functions of Lyman-alpha emitters

, 2009
We present a semi-analytical model of star formation which explains simultaneously the observed UV luminosity function of high redshift Lyman break galaxies (LBGs) and luminosity functions of Lyman-alpha emitters.

The JWST/PASSAGE Survey: Testing Reionization Histories with JWST’s First Unbiased Survey for Lyα Emitters at Redshifts 7.5–9.5

The Astrophysical Journal
Ly α emission is one of a few observable features of galaxies that can trace the neutral hydrogen content in the Universe during the Epoch of Reionization (EoR). To accomplish this, we need an efficient way to survey for Ly α emitters (LAEs) at redshifts

Stellar abundances and molecular hydrogen in high-redshift galaxies -the far-ultraviolet view

, 2006
FUSE spectra of star-forming regions in nearby galaxies are compared to composite spectra of Lyman-break galaxies (LBGs), binned by strength of Lyman alpha emission and by mid-UV luminosity.

Lyman-alpha Imaging of a Very Luminous z=2.3 Starburst Galaxy with WFPC2 [PDF]

, 2000
We investigate a very luminous Lyman-alpha emitting galaxy, associated with a z=2.3 damped absorption system in the spectrum of the QSO PHL 957. The galaxy was observed with the HST WFPC2, through a narrow filter (F410M) corresponding to rest-frame Lyman
