The molecular gas content of high-redshift galaxies is a highly sought-after property. However, H2 is not directly observable in most environments, so its mass is probed through other emission lines (e.g. CO, [C i], [C ii]), or through a gas-to-dust ratio. Each of these methods depends on several assumptions, and are best used in parallel. In this work, we extend an additional molecular gas tracer to high-redshift studies by observing hydrogen deuteride (HD) emission in the strongly lensed z…

Multiphase ISM in the z = 5.7 Hyperluminous Starburst SPT 0346–52
With ΣSFR ∼ 4200 M ⊙ yr−1 kpc−2, SPT 0346–52 (z = 5.7) is the most intensely star-forming galaxy discovered by the South Pole Telescope. In this paper, we expand on previous spatially resolved

Dust Masses, PAH Abundances, and Starlight Intensities in the SINGS Galaxy Sample
Physical dust models are presented for 65 galaxies in SINGS that are strongly detected in the four IRAC bands and three MIPS bands. For each galaxy we estimate (1) the total dust mass, (2) the
SUB-KILOPARSEC IMAGING OF COOL MOLECULAR GAS IN TWO STRONGLY LENSED DUSTY, STAR-FORMING GALAXIES
We present spatially resolved imaging obtained with the Australia Telescope Compact Array (ATCA) of three CO lines in two high-redshift gravitationally lensed dusty star-forming galaxies, discovered
Low Star Formation Efficiency in Typical Galaxies at z = 5–6
Using the Very Large Array and ALMA, we have obtained CO(2–1), [C ii], and [N ii] line emission and multiple dust continuum measurements in a sample of “normal” galaxies at z = 5–6. We report the
STELLAR MASSES AND STAR FORMATION RATES OF LENSED, DUSTY, STAR-FORMING GALAXIES FROM THE SPT SURVEY
To understand cosmic mass assembly in the universe at early epochs, we primarily rely on measurements of the stellar masses and star formation rates (SFRs) of distant galaxies. In this paper, we
A survey of the cold molecular gas in gravitationally lensed star-forming galaxies at z > 2
Using the Australia Telescope Compact Array, we conducted a survey of CO J = 1 − 0 and J = 2 − 1 line emission towards strongly lensed high-redshift dusty star-forming galaxies (DSFGs) previously
Cool Gas in High-Redshift Galaxies
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
Deceptively cold dust in the massive starburst galaxy GN20 at z ∼ 4
We present new observations, carried out with IRAM NOEMA, of the atomic neutral carbon transitions [C I](3P1–3P0) at 492 GHz and [C I](3P2–3P1) at 809 GHz of GN20, a well-studied star-bursting galaxy
Dusty starburst galaxies in the early Universe as revealed by gravitational lensing
TLDR
A redshift survey at a wavelength of three millimetres, targeting carbon monoxide line emission from the star-forming molecular gas in the direction of extraordinarily bright millimetre-wave-selected sources, indicating that the fraction of dusty starburst galaxies at high redshifts is greater than previously thought.
VALIDATION OF THE EQUILIBRIUM MODEL FOR GALAXY EVOLUTION TO z ∼ 3 THROUGH MOLECULAR GAS AND DUST OBSERVATIONS OF LENSED STAR-FORMING GALAXIES*
We combine IRAM Plateau de Bure Interferometer and Herschel PACS and SPIRE measurements to study the dust and gas contents of high-redshift star-forming galaxies. We present new observations for a
Witnessing Galaxy Assembly at the Edge of the Reionization Epoch
We report the discovery of Serenity-18, a galaxy at z ≃ 5.939 for which we could measure the content of molecular gas, M(H2) ≃ 5 × 109 M⊙, traced by the CO(6–5) emission, together with the metal-poor
