Overview of the JWST Advanced Deep Extragalactic Survey (JADES)

open access: yesThe Astrophysical Journal Supplement Series
We present an overview of the James Webb Space Telescope (JWST) Advanced Deep Extragalactic Survey (JADES), an ambitious program of infrared imaging and spectroscopy in the GOODS-S and GOODS-N deep fields, designed to study galaxy evolution from high ...

Compact Ionized Gas Region Surrounded by Porous Neutral Gas in a Dusty Lyman Break Galaxy at Redshift z = 8.312

open access: yesThe Astrophysical Journal
Porous interstellar medium (ISM) structure in galaxies at the epoch of reionization gives us a hint to understand what types of galaxies contribute to reionization.

Predicting Multi-Wavelength Properties of Lyman Break Galaxies with GalICS

open access: yesAstrophysics and Space Science, 2003
GalICS (for GALaxies In Cosmological Simulations) is a model of hierarchical galaxy formation which combines high resolution numerical simulations for the dark matter component with semi-analytic prescriptions for the baryonic matter. It provides us with an explicit cosmological framework to analyse observations of distant galaxies, and to understand ...

Low-redshift Analogs of Cosmic Noon Galaxies as Laboratories for Clumpy Star Formation

open access: yesThe Astrophysical Journal
It has been established that a significant fraction of star formation at high redshift occurs in clumpy galaxies. The properties of clumps and their formation mechanisms, however, remain highly debated. In this work we analyze a sample of 18 supercompact

Using Gravitational Lensing to Probe for Candidate Quintessential Galaxies in the Epoch of Reionization

open access: yesThe Astrophysical Journal
Understanding the properties of the first generation of galaxies is an ongoing challenge in observational astrophysics. James Webb Space Telescope deep-field observations have led to the identification of large numbers of galaxies within the Epoch of ...
