Quantifying the decline in CO(2-1) intensity around PHANGS-HST star clusters: Constraints on molecular gas dispersal, stellar feedback, and cluster formation efficiency
Hao He, Adam K. Leroy, Erik Rosolowsky +37
We combine the largest survey of star clusters in nearby galaxies to-date, PHANGS-HST, with maps of molecular gas maps from PHANGS-ALMA to constrain the efficiency of cluster forma…
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…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN): III. CO/CO ratio variations across the M51 galaxy
Ina Galić, 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…
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…
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 l…
Dense gas scaling relations at kiloparsec scales across nearby galaxies with the ALMA ALMOND and IRAM 30m EMPIRE surveys
Lukas Neumann, Maria J. Jimenez-Donaire, Adam K. Leroy +17
Dense, cold gas is the key ingredient for star formation. Over the last two decades, HCN(1-0) emission has been utilised as the most accessible dense gas tracer to study external g…
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…
Does the HCN/CO ratio trace the star-forming fraction of gas? II. Variations in CO and HCN Emissivity
Ashley R. Bemis, Christine D. Wilson, Piyush Sharda +2
We model emissivities of the HCN and CO transitions using measured properties of clouds found in normal star forming galaxies and more extreme systems. These models are com…
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…
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}}…
Hidden Gems on a Ring: Infant Massive Clusters and Their Formation Timeline Unveiled by ALMA, HST, and JWST in NGC 3351
Jiayi Sun, Hao He, Kyle Batschkun +38
We study young massive clusters (YMCs) in their embedded "infant" phase with ALMA, HST, and JWST observations targeting the central starburst ring in NGC…
