Sizing Up Ly Alpha and Lyman Break Galaxies

, 2012
We measure the sizes for a sample of 174 Ly alpha-selected galaxies with broadband imaging with the Hubble Space Telescope. Over the redshift range 2.25 < z < 6, Ly alpha-selected galaxies have a characteristic, constant, small size in rest-frame ...

ODIN: Probing the LAE Lyα Luminosity Function across Cosmic Time and Different Environments

The Astrophysical Journal
The ubiquity and relative ease of discovery make 2 ≲  z  ≲ 5 Ly α emitting galaxies (LAEs) ideal tracers for large-scale structure of the distant Universe.

Modelling of the Lyman-alpha emission in high redshift galaxies and cosmological simulations

, 2011
Depuis une quinzaine d'années, de nombreuses galaxies sont détectées grâce à leur raie d'émission Lyman-alpha à des décalages spectraux supérieurs à 3.

The Sunburst Arc with JWST. IV. The Importance of Interaction, Turbulence, and Feedback for Lyman-continuum Escape

The Astrophysical Journal
At present, the best opportunity for detailed Lyman continuum (LyC) escape studies is in gravitationally lensed galaxies at z  ≳ 2. Only one such galaxy currently exists in the literature with sufficient magnification and spatial resolution: the Sunburst

The Lyman-alpha emission from the circumgalactic medium of distant galaxies observed through gravitational lensing with MUSE/VLT

, 2021
Les galaxies sont entourées d'une grande quantité de gaz très étendu, principalement composé d'hydrogène froid. Cette région appelée, milieu circumgalactique (CGM), est le lieu des échanges de gaz entre la galaxie et son milieu environnant, et est par ...
