CO-to-H conversion factor and grain size distribution through the analysis of - relation
I-Da Chiang, Hiroyuki Hirashita, Jeremy Chastenet +5
The CO-to-H conversion factor () is expected to vary with dust abundance and grain size distribution through the efficiency of shielding gas from CO-dissociation…
CO isotopologue-derived molecular gas conditions and CO-to-H conversion factors in M51
Jakob den Brok, María J. Jiménez-Donaire, Adam Leroy +24
Over the past decade, several millimeter interferometer programs have mapped the nearby star-forming galaxy M51 at a spatial resolution of pc. This study combines observ…
Polycyclic Aromatic Hydrocarbon and CO(2-1) Emission at 50-150 pc Scales in 70 Nearby Galaxies
Ryan Chown, Adam K. Leroy, Karin Sandstrom +44
Combining Atacama Large Millimeter/sub-millimeter Array CO(2-1) mapping and JWST near- and mid-infrared imaging, we characterize the relationship between CO(2-1) and polycyclic aro…
PHANGS-MeerKAT and MHONGOOSE HI observations of nearby spiral galaxies: physical drivers of the molecular gas fraction,
Cosima Eibensteiner, Jiayi Sun, Frank Bigiel +36
The molecular-to-atomic gas ratio is crucial to the evolution of the interstellar medium in galaxies. We investigate the balance between the atomic () and molecular gas…
A 260 pc resolution ALMA map of HCN(1-0) in the galaxy NGC 4321
Lukas Neumann, Frank Bigiel, Ashley T. Barnes +24
The star formation rate (SFR) is tightly connected to the amount of dense gas in molecular clouds. However, it is not fully understood how the relationship between dense molecular…
Unraveling the Mystery of the Low CO-to-H Conversion Factor in Starburst Galaxies: RADEX Modeling of the Antennae
Hao He, Christine D. Wilson, Jiayi Sun +3
CO emission has been widely used as a tracer of molecular gas mass. However, it is a long-standing issue to accurately constrain the CO-to-H conversion factor ($α_{\mathrm{CO}}…
PHANGS-JWST: Data Processing Pipeline and First Full Public Data Release
Thomas G. Williams, Janice C. Lee, Kirsten L. Larson +55
The exquisite angular resolution and sensitivity of JWST is opening a new window for our understanding of the Universe. In nearby galaxies, JWST observations are revolutionizing ou…
