The spatial distribution of Lyman alpha from star-forming galaxies in the low redshift Universe

, 2022
The Lyman alpha (Lyα) emission line from the recombination of hydrogen atoms is predicted to be the strongest spectral feature of galaxies. This emission line is regularly used to detect and characterise high redshift galaxies.

ODIN: Searching for LyC Emission from Lyα Emitters at z = 4.5 in the E-COSMOS and XMM-LSS Fields

The Astrophysical Journal
We investigated Lyman-continuum (LyC) emission from Lyman-alpha emitters (LAEs) at z = 4.5, identified in the One-hundred-deg ^2 DECam Imaging in Narrowbands (ODIN) survey.

The nature and origin of disky elliptical galaxies [PDF]

, 2002
The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

Evidence for Spatially Compact Lyman Alpha Emission in z=3.1 Lyman-Alpha-Emitting Galaxies

, 2010
We present the results of a high-spatial-resolution study of the line emission in a sample of z=3.1 Lyman-Alpha-Emitting Galaxies (LAEs) in the Extended Chandra Deep Field-South. Of the eight objects with coverage in our HST/WFPC2 narrow-band imaging, two have clear detections and an additional two are barely detected (~2-sigma).

Radiative transfer simulations of Lyman-alpha photons in the universe [PDF]

, 2021
The Lyman-alpha emission line is one of the brightest lines in the high-redshift Universe. With new instruments and surveys mapping larger areas of the sky with higher spectral resolving power, spatial resolution, and depth, Lyman-alpha observations are ...

MOSEL Survey: Spatially Offset Lyman-continuum Emission in a New Emitter at z = 3.088 Can Explain the Low Number Density of Observed LyC Leakers

The Astrophysical Journal
We present the discovery of a unique Lyman-continuum (LyC) emitter at z = 3.088. The LyC emission was detected using the Hubble Space Telescope WFC3/UVIS F336W filter, covering a rest-frame wavelength range of 760–900 Å. The peak signal-to-noise ratio of
