Molecular Gas and the Star-Formation Process on Cloud Scales in Nearby Galaxies
E Schinnerer, AK Leroy - Annual Review of Astronomy and …, 2024 - annualreviews.org
Observations that resolve nearby galaxies into individual regions across multiple phases of
the gas–star formation feedback “matter cycle” have provided a sharp new view of molecular …

Pressure-regulated, feedback-modulated star formation in disk galaxies
EC Ostriker, CG Kim - The Astrophysical Journal, 2022 - iopscience.iop.org
The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …

Dust, CO, and [C i]: cross-calibration of molecular gas mass tracers in metal-rich galaxies across cosmic time
L Dunne, SJ Maddox, PP Papadopoulos… - Monthly Notices of …, 2022 - academic.oup.com
We present a self-consistent cross-calibration of the three main molecular gas mass tracers

Low-J CO line ratios from single-dish CO map** surveys and PHANGS-ALMA
AK Leroy, E Rosolowsky, A Usero… - The Astrophysical …, 2022 - iopscience.iop.org
We measure the low-J CO line ratios R 21≡ CO (2–1)/CO (1–0), R 32≡ CO (3–2)/CO (2–1),
and R 31≡ CO (3–2)/CO (1–0) using whole-disk CO maps of nearby galaxies. We draw CO …

Star formation efficiency and dispersal of giant molecular clouds with UV radiation feedback: dependence on gravitational boundedness and magnetic fields
JG Kim, EC Ostriker, N Filippova - The Astrophysical Journal, 2021 - iopscience.iop.org
Molecular clouds are supported by turbulence and magnetic fields, but quantifying their
influence on cloud life cycle and star formation efficiency (SFE) remains an open question …

The physical drivers and observational tracers of CO-to-H2 conversion factor variations in nearby barred galaxy centers
The CO-to-H 2 conversion factor (α CO) is central to measuring the amount and properties of
molecular gas. It is known to vary with environmental conditions, and previous studies have …
