THE CO-TO-H<sub>2</sub>CONVERSION FACTOR FROM INFRARED DUST EMISSION ACROSS THE LOCAL GROUP
THE CO-TO-H<sub>2</sub>CONVERSION FACTOR FROM INFRARED DUST EMISSION ACROSS THE LOCAL GROUP
We estimate the conversion factor relating CO emission to H2 mass, alpha_CO, in five Local Group galaxies that span approximately an order of magnitude in metallicity - M31, M 33, the Large Magellanic Cloud (LMC), NGC 6822, and the Small Magellanic Cloud (SMC). We model the dust mass along the …
