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

Discovery and properties of ultra-high redshift galaxies (9 < z < 12) in the JWST ERO SMACS 0723 Field [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We present a reduction and analysis of the James Webb Space Telescope (JWST) SMACS 0723 field using new post-launch calibrations to conduct a search for ultra-high-redshift galaxies (z > 9) present within the Epoch of Reionisation.

Stress testing ΛCDM with high-redshift galaxy candidates [PDF]
Nature Astronomy, 2022 Early James Webb Space Telescope (JWST) results suggest a high level of star formation in the first 500 million years of the Universe. A study of the available mass from dark matter haloes shows that unexpectedly high-mass JWST galaxy candidates may ...

A UNIVERSAL, LOCAL STAR FORMATION LAW IN GALACTIC CLOUDS, NEARBY GALAXIES, HIGH-REDSHIFT DISKS, AND STARBURSTS [PDF]
, 2011 Star formation laws are rules that relate the rate of star formation in a particular region, either an entire galaxy or some portion of it, to the properties of the gas, or other galactic properties, in that region.

“Direct” Gas-phase Metallicity in Local Analogs of High-redshift Galaxies: Empirical Metallicity Calibrations for High-redshift Star-forming Galaxies [PDF]
Astrophysical Journal, 2018 We study the direct gas-phase oxygen abundance using the well-detected auroral line [O iii]λ4363 in the stacked spectra of a sample of local analogs of high-redshift galaxies.

Massive and old quiescent galaxies at high redshift [PDF]
Astronomy & Astrophysics, 2019 Aims. Questions of how massive quiescent galaxies rapidly assembled and how abundant they are at high redshift are increasingly important in the study of galaxy formation.

Dust Attenuation Curves in the Local Universe: Demographics and New Laws for Star-forming Galaxies and High-redshift Analogs [PDF]
, 2018 We study the dust attenuation curves of 230,000 individual galaxies in the local universe, ranging from quiescent to intensely star-forming systems, using GALEX, SDSS, and WISE photometry calibrated on the Herschel ATLAS.

Extreme value statistics of the halo and stellar mass distributions at high redshift: are JWST results in tension with ΛCDM? [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The distribution of dark matter halo masses can be accurately predicted in the ΛCDM cosmology. The presence of a single massive halo or galaxy at a particular redshift, assuming some baryon and stellar fraction for the latter, can therefore be used to ...

The HDUV Survey: A Revised Assessment of the Relationship between UV Slope and Dust Attenuation for High-redshift Galaxies [PDF]
, 2017 We use a newly assembled sample of 3545 star-forming galaxies with secure spectroscopic, grism, and photometric redshifts at z = 1.5–2.5 to constrain the relationship between UV slope (β) and dust attenuation (LIR/LUV ≡ IRX).
