The cosmic baryon and metal cycles
C Péroux, JC Howk - Annual Review of Astronomy and …, 2020 - annualreviews.org
Characterizing the relationship between stars, gas, and metals in galaxies is a critical
component of understanding the cosmic baryon cycle. We compile contemporary censuses …

From diffuse gas to dense molecular cloud cores
Molecular clouds are a fundamental ingredient of galaxies: they are the channels that
transform the diffuse gas into stars. The detailed process of how they do it is not completely …

Tracing the total molecular gas in galaxies:[CII] and the CO-dark gas
Context. Molecular gas is a necessary fuel for star formation. The CO (1− 0) transition is
often used to deduce the total molecular hydrogen but is challenging to detect in low …

Cloud-scale molecular gas properties in 15 nearby galaxies
We measure the velocity dispersion, σ, and surface density, Σ, of the molecular gas in
nearby galaxies from CO spectral line cubes with spatial resolution 45–120 pc, matched to …

Introducing TIGRESS-NCR. I. Coregulation of the Multiphase Interstellar Medium and Star Formation Rates
Massive, young stars are the main source of energy that maintains multiphase structure and
turbulence in the interstellar medium (ISM), and without this" feedback" the star formation …

Star formation efficiency and dispersal of giant molecular clouds with UV radiation feedback: dependence on gravitational boundedness and magnetic fields
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 …

The Environmental Dependence of the XCO Conversion Factor
CO is the most widely used observational tracer of molecular gas. The observable CO
luminosity is translated to H2 mass via a conversion factor, XCO, which is a source of …

Resolved Measurements of the CO-to-H2 Conversion Factor in 37 Nearby Galaxies
We measure the CO-to-H 2 conversion factor (α CO) in 37 galaxies at 2 kpc resolution, using
the dust surface density inferred from far-infrared emission as a tracer of the gas surface …

Metallicity dependence of the H/H2 and C+/C/CO distributions in a resolved self-regulating interstellar medium
We study the metallicity dependence of the H/H 2 and C+/C/CO distributions in a self-
regulated interstellar medium (ISM) across a broad range of metallicities (0.1< Z/Z⊙< 3). To …
