The Link Between Dust Emission and Molecular Gas Mass

11 May 2018

A paper on the use of dust continuum emission as a tracer of the molecular mass in galaxies (Privon+) has been submitted to the American Astronomical Society Journals. A preprint is available and I welcome any comments on the manuscript. In this paper we use hydrodynamic cosmological zoom simulations to explore the link between optically thin dust continuum emission and the total molecular mass in galaxies. We find the dust emission is a good tracer of the molecular mass for massive galaxies, but the relation may break down due to metallicity-driven variations in the dust-to-gas ratio.
