Low-J CO Line Ratios From Single Dish CO Mapping Surveys and PHANGS-ALMA
Adam K. Leroy, Erik Rosolowsky, Antonio Usero +32
We measure the low-J CO line ratio R21=CO(2-1)/CO(1-0), R32=CO(3-2)/CO(2-1), and R31 = CO(3-2)/CO(1-0) using whole-disk CO maps of nearby galaxies. We draw CO(2-1) from PHANGS--ALM…

We analyse the far-infrared properties of 5,000 star-forming galaxies at , drawn from the deepest, super-deblended catalogues in the GOODS-N and COSMOS fields. We dev…
The effect of active galactic nuclei on the cold interstellar medium in distant star-forming galaxies
