Resolved Measurements of the CO-to-H Conversion Factor in 37 Nearby Galaxies
I-Da Chiang, Karin M. Sandstrom, Jeremy Chastenet +6
We measure the CO-to-H conversion factor () in 37 galaxies at 2~kpc resolution, using dust surface density inferred from far-infrared emission as a tracer of the…

Resolved low-J CO excitation at 190 parsec resolution across NGC 2903 and NGC 3627
J. S. den Brok, A. K. Leroy, A. Usero +14
The low- rotational transitions of CO are commonly used to trace the distribution of molecular gas in galaxies. Their ratios are sensitive to excitation and physical cond…

Physical Conditions and Kinematics of the Filamentary Structure in Orion Molecular Cloud 1
Yu-Hsuan Teng, Naomi Hirano
We have studied the structure and kinematics of the dense molecular gas in the Orion Molecular Cloud 1 (OMC1) region with the N2H+ 3-2 line. The 6'x9' (~0.7x1.1 pc) region surround…
