First Light: exploring the Spectra of High-Redshift Galaxies in the Renaissance Simulations [PDF]

, 2017
We present synthetic observations for the first generations of galaxies in the Universe and make predictions for future deep field observations for redshifts greater than 6.

Globular clusters as the relics of regular star formation in ‘normal’ high-redshift galaxies [PDF]

, 2015
We present an end-to-end, two-phase model for the origin of globular clusters (GCs). In the model, populations of stellar clusters form in the high-pressure discs of high-redshift ($z>2$) galaxies (a rapid-disruption phase due to tidal perturbations from

The problematic growth of dust in high-redshift galaxies [PDF]

, 2016
Dust growth via accretion of gas species has been proposed as the dominant process to increase the amount of dust in galaxies. We show here that this hypothesis encounters severe difficulties that make it unfit to explain the observed UV and IR ...

Unveiling the Cosmic Chemistry. II. “Direct” Te-based Metallicity of Galaxies at 3 < z < 10 with JWST/NIRSpec

The Astrophysical Journal
We report the detection of the [O iii ] auroral line in 42 galaxies within the redshift range of 3 < z < 10. These galaxies were selected from publicly available JWST data releases, including the JADES and PRIMAL surveys, and observed using both the low ...

Early Results from GLASS-JWST. IX. First Spectroscopic Confirmation of Low-mass Quiescent Galaxies at z > 2 with NIRISS

The Astrophysical Journal Letters, 2023
How passive galaxies form, and the physical mechanisms which prevent star formation over long timescales, are some of the most outstanding questions in understanding galaxy evolution.

Why do high-redshift galaxies show diverse gas-phase metallicity gradients? [PDF]

, 2016
Recent spatially resolved observations of galaxies at z ∼ 0.6–3 reveal that high-redshift galaxies show complex kinematics and a broad distribution of gas-phase metallicity gradients.

Reionisation and High-Redshift Galaxies: The View from Quasar Absorption Lines [PDF]

Publications Astronomical Society of Australia, 2015
Determining when and how the first galaxies reionised the intergalactic medium promises to shed light on both the nature of the first objects and the cosmic history of baryons.
