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…
Dense molecular gas properties on 100 pc scales across the disc of NGC 3627
I. Bešlić, A. T. Barnes, F. Bigiel +29
It is still poorly constrained how the densest phase of the interstellar medium varies across galactic environment. A large observing time is required to recover significant emissi…
PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-Forming Galaxies
Adam K. Leroy, Eva Schinnerer, Annie Hughes +69
We present PHANGS-ALMA, the first survey to map CO J=2-1 line emission at ~1" ~ 100pc spatial resolution from a representative sample of 90 nearby (d<~20 Mpc) galaxies that lie on…
PHANGS-ALMA Data Processing and Pipeline
Adam K. Leroy, Annie Hughes, Daizhong Liu +65
We describe the processing of the PHANGS-ALMA survey and present the PHANGS-ALMA pipeline, a public software package that processes calibrated interferometric and total power data…
New Constraints on the CO(2-1)/(1-0) Line Ratio Across Nearby Disc Galaxies
J. S. den Brok, D. Chatzigiannakis, F. Bigiel +18
Both the CO(2-1) and CO(1-0) lines are used to trace the mass of molecular gas in galaxies. Translating the molecular gas mass estimates between studies using different lines requi…
