The Structure of Molecular Gas in PHANGS-ALMA Galaxies: Cloud Spacing, Two-Point Correlation and Stacked Intensity Profiles
Hao He, Adam Leroy, Erik Rosolowsky +21
The sub-kpc scale gas structure encodes key information of giant molecular cloud (GMC) formation. Therefore, we aim for a quantitative description of molecular gas structure across…
The Hierarchical Dynamical State of Molecular Gas from 3 to 300 pc in NGC 253
Elias K. Oakes, Christopher M. Faesi, Erik Rosolowsky +25
Understanding how the dynamical state of the interstellar medium (ISM) changes across spatial scales can provide important insights into how the gas is organized and ultimately col…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN): III. CO/CO ratio variations across the M51 galaxy
Ina GaliÄ, Mallory Thorp, Frank Bigiel +16
CO isotopologues are common tracers of the bulk molecular gas in extragalactic studies, providing insights into the physical and chemical conditions of the cold molecular gas, a re…
Constraining resolved extragalactic variation with well calibrated ALMA observations
Jakob den Brok, Elias K. Oakes, Adam K. Leroy +13
CO(1-0) and CO(2-1) are commonly used as bulk molecular gas tracers. The CO line ratios (especially CO(2-1)/CO(1-0) - ) vary within and among galaxies, yet previous studies…
Relationships between PAHs, Small Dust Grains, H, and HI in Local Group Dwarf Galaxies NGC 6822 and WLM Using JWST, ALMA, and the VLA
Ryan Chown, Adam K. Leroy, Alberto D. Bolatto +27
We present 0.7-3.3 pc resolution mid-infrared (MIR) JWST images at 7.7 m (F770W) and 21 m (F2100W) covering the main star-forming regions of two of the closest star-forming…
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…
