Early Results From GLASS-JWST. XII. The Morphology of Galaxies at the Epoch of Reionization
The Astrophysical Journal Letters, 2023 Star-forming galaxies can exhibit strong morphological differences between the rest-frame far-UV and optical, reflecting inhomogeneities in star formation and dust attenuation.

The IRX–β relation of high-redshift galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT The relation between infrared excess (IRX) and UV spectral slope (βUV) is an empirical probe of dust properties of galaxies. The shape, scatter, and redshift evolution of this relation are not well understood, however, leading to uncertainties in estimating the dust content and star formation rates (SFRs) of galaxies at high ...

The circumgalactic medium of high-redshift galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract We study the properties of the circumgalactic medium (CGM) of high-z galaxies in the metal enrichment simulations presented in Pallottini et al. At z = 4, we find that the simulated CGM gas density profiles are self-similar, once scaled with the virial radius of the parent dark matter halo.

Modelling galaxy clustering at high redshift [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We discuss the theoretical interpretation of observational data concerning the clustering of galaxies at high redshifts. Building on the theoretical machinery developed by Matarrese et al. (1997), we make detailed quantitative predictions of galaxy clustering statistics for a variety of cosmological models, taking into account differences in spatial ...

CEERS Key Paper. III. The Diversity of Galaxy Structure and Morphology at z = 3–9 with JWST
The Astrophysical Journal Letters, 2023 We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3–9 using early James Webb Space Telescope (JWST) CEERS NIRCam observations. Our sample consists of 850 galaxies at z

Cool Gas in High-Redshift Galaxies [PDF]
Annual Review of Astronomy and Astrophysics, 2013 Over the past decade, observations of the cool interstellar medium (ISM) in distant galaxies via molecular and atomic fine structure line (FSL) emission have gone from a curious look into a few extreme, rare objects to a mainstream tool for studying galaxy formation out to the highest redshifts. Molecular gas has been observed in close to 200 galaxies
