Emission from Interstellar Gas and Dust in M31
Published online by Cambridge University Press: 03 August 2017
Abstract
We present preliminary results of a comparison of the spatial distributions of 100 μm, Hi and CO emission in M31. Using a scatter diagram of 100 μm intensity versus H i column density, we have derived an upper limit to the molecular gas column density. We have compared these values with the velocity-integrated CO intensity to find an upper limit to the CO-to-H2 conversion factor in the ring of M 31 of 5 1020 mol cm—2 [K km s—1]—1.
