Resolved Measurements of the CO-to-H2 Conversion Factor in 37 Nearby Galaxies [PDF]
Astrophysical Journal, 2023 We measure the CO-to-H2 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 density and assuming a constant dust-to-metal ratio. In total, we have ∼

The Environmental Dependence of the XCO Conversion Factor [PDF]
Astrophysical Journal, 2020 is the most widely used observational tracer of molecular gas. The observable luminosity is translated to mass via a conversion factor, , which is a source of uncertainty and bias.

Direct Measurement of the [C i] Luminosity to Molecular Gas Mass Conversion Factor in High-redshift Star-forming Galaxies [PDF]
Astrophysical Journal, 2020 The amount of cold, molecular gas in high-redshift galaxies is typically inferred from proxies of molecular hydrogen (H2), such as carbon monoxide (CO) or neutral atomic carbon ([C i]) and molecular gas mass conversion factors.

The CO-to-H2 Conversion Factor [PDF]
, 2013 CO line emission represents the most accessible and widely used tracer of the molecular interstellar medium. This renders the translation of observed CO intensity into total H2 gas mass critical to understand star formation and the interstellar medium in
