A general model for the CO-H2 conversion factor in galaxies with applications to the star formation law

Narayanan, Desika; Krumholz, Mark; Ostriker, Eve C.; Hernquist, Lars


The most common means of converting an observed CO line intensity into a molecular gas mass requires the use of a conversion factor (XCO). While in the Milky Way this quantity does not appear to vary significantly, there is good reason to believe that XCO will depend on the larger‐scale galactic environment. With sensitive instruments pushing detections to increasingly high redshift, characterizing XCO as a function of physical conditions is crucial to our understanding of galaxy evolution....[Show more]
