On the dust temperatures of high-redshift galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Dust temperature is an important property of the interstellar medium (ISM) of galaxies. It is required when converting (sub)millimetre broad-band flux to total infrared luminosity (LIR), and hence star formation rate, in high-redshift galaxies. However,

Galaxy formation at high redshifts [PDF]
Nature, 1996 Sensitive optical surveys have revealed a large population of `faint blue galaxies' which are believed to be young galaxies, observed close to their time of formation. But there has been considerable uncertainty regarding the epochs at which these galaxies are observed, owing to the difficulties inherent in determining spectroscopic redshifts for very ...

Dust in High‐Redshift Galaxies [PDF]
The Astrophysical Journal, 1997 Measurements of Zn and Cr abundances in damped Lyman alpha systems at absorption redshifts between 0.692 and 3.390 show that metals and dust are much less abundant in high redshift galaxies than in the Milky Way today. We conclude that the overall degree of metal enrichment of DLA galaxies approximately 13.5 Gyr ago is 1/15 solar.

“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.

Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
The Astrophysical Journal, 2023 We introduce the DESI LOW- Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method.

A fundamental relation between mass, SFR and metallicity in local and high redshift galaxies [PDF]
, 2010 We show that the mass-metallicity relation observed in the local universe is due to a more general relation between stellar mass M*, gas-phase metallicity and SFR.

The Puzzling Properties of the MACS1149-JD1 Galaxy at z = 9.11
The Astrophysical Journal Letters, 2023 We analyze new JWST NIRCam and NIRSpec data on the redshift 9.11 galaxy MACS1149-JD1 (hereafter JD1). Our NIRCam imaging data reveal that JD1 comprises three spatially distinct components. Our spectroscopic data indicate that JD1 appears dust free but is
