Resolved Measurements of the CO-to-H2 Conversion Factor in 37 Nearby Galaxies

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 density and assuming a constant dust-to-metal ratio. In total, we have ∼790 and ∼610 independent measurements of...
