The CO-to-H2 Conversion Factor and Dust-to-Gas Ratio on Kiloparsec Scales in Nearby Galaxies

K. M. Sandstrom, A. K. Leroy, F. Walter +42

We present kiloparsec (kpc) spatial resolution maps of the CO-to-H2 conversion factor (alpha_co) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneo…

The Molecular Interstellar Medium of the Local Group Dwarf NGC6822

P. Gratier, J. Braine, N. J. Rodriguez-Fernandez +4

Do molecular clouds collapse to form stars at the same rate in all environments? In large spiral galaxies, the rate of transformation of H2 into stars (hereafter SFE) varies little…
