ZEN2: A narrow J-band search for z~9 Lya emitting galaxies directed towards three lensing clusters [PDF]

, 2007
We present the results of a continuing survey to detect Lya emitting galaxies at redshifts z~9: the ZEN ("z equals nine'') survey. We have obtained deep VLT/ISAAC observations in the narrow J-band filter NB119 directed towards three massive lensing ...

Resolving dust and Lyman α emission in a lensed galaxy at the epoch of reionization with JWST/CANUCS

Astronomy & Astrophysics
Context. Lyman α (Lyα) emission is highly sensitive to dust and neutral hydrogen and is believed to be suppressed in dusty or hydrogen-rich galaxies – especially during the epoch of reionization (EoR).

The Kinematics of Multiple-Peaked Lyα Emission in Star-Forming Galaxies at z ~ 2-3 [PDF]

, 2012
We present new results on the Lyα emission-line kinematics of 18 z ~ 2-3 star-forming galaxies with multiple-peaked Lyα profiles. With our large spectroscopic database of UV-selected star-forming galaxies at these redshifts, we have determined that ~30 ...

Physical properties of z~4 LBGs: differences between galaxies with and without Ly-alpha emission

, 2007
We have analysed the physical properties of z~4 Lyman Break Galaxies observed in the GOODS-S survey, in order to investigate the possible differences between galaxies where the Ly-alpha is present in emission, and those where the line is absent or in ...

MAMMOTH-Subaru. IV. Large Scale Structure and Clustering Analysis of Lyα Emitters and Lyα Blobs at z = 2.2–2.3

The Astrophysical Journal
We report the large scale structure and clustering analysis of Ly α emitters (LAEs) and Ly α blobs (LABs) at z  = 2.2–2.3. Using 3341 LAEs, 117 LABs, and 58 bright (Ly α luminosity L _Ly _α  > 10 ^43.4 erg s ^−1 ) LABs at z  = 2.2–2.3 selected with ...

Gas Accretion and Giant Lyman-alpha Nebulae

, 2016
Several decades of observations and discoveries have shown that high-redshift AGN and massive galaxies are often surrounded by giant Lyman-alpha nebulae extending in some cases up to 500 kpc in size.

Detecting Early Galaxies Through Their 21-cm Signature [PDF]

, 2007
New observations over the next few years of the emission of distant objects will help unfold the chapter in cosmic history around the era of the first galaxies. These observations will use the neutral hydrogen emission or absorption at a wavelength of 21-
