Molecular clouds in the Trifid nebula M20; Possible evidence for a cloud-cloud collision in triggering the formation of the first generation stars
K. Torii, R. Enokiya, H. Sano +14
A large-scale study of the molecular clouds toward the Trifid nebula, M20, has been made in the J=2-1 and J=1-0 transitions of 12CO and 13CO. M20 is ionized predominantly by an O7.…

The CO-to-H2 Conversion Factor From Infrared Dust Emission Across the Local Group
Adam K. Leroy, Alberto Bolatto, Karl Gordon +8
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,…
