PHANGS-JWST First Results: Mid-infrared emission traces both gas column density and heating at 100 pc scales
Adam K. Leroy, Karin Sandstrom, Erik Rosolowsky +48
We compare mid-infrared (mid-IR), extinction-corrected H, and CO (2-1) emission at 70--160 pc resolution in the first four PHANGS-JWST targets. We report correlation strengths,…
PHANGS-JWST First Results: A Global and Moderately Resolved View of Mid-Infrared and CO Line Emission from Galaxies at the Start of the JWST Era
Adam K. Leroy, Alberto D. Bolatto, Karin Sandstrom +41
We explore the relationship between mid-infrared (mid-IR) and CO rotational line emission from massive star-forming galaxies, which is one of the tightest scalings in the local uni…
PHANGS-JWST First Results: Tracing the Diffuse ISM with JWST Imaging of Polycyclic Aromatic Hydrocarbon Emission in Nearby Galaxies
Karin M. Sandstrom, Eric W. Koch, Adam K. Leroy +43
JWST observations of polycyclic aromatic hydrocarbon (PAH) emission provide some of the deepest and highest resolution views of the cold interstellar medium (ISM) in nearby galaxie…
PHANGS-JWST First Results: Rapid Evolution of Star Formation in the Central Molecular Gas Ring of NGC1365
Eva Schinnerer, Eric Emsellem, Jonathan D. Henshaw +36
Large-scale bars can fuel galaxy centers with molecular gas, often leading to the development of dense ring-like structures where intense star formation occurs, forming a very diff…
The PHANGS-JWST Treasury Survey: Star Formation, Feedback, and Dust Physics at High Angular resolution in Nearby GalaxieS
Janice C. Lee, Karin M. Sandstrom, Adam K. Leroy +74
The PHANGS collaboration has been building a reference dataset for the multi-scale, multi-phase study of star formation and the interstellar medium in nearby galaxies. With the suc…
PHANGS-JWST First Results: Duration of the early phase of massive star formation in NGC628
Jaeyeon Kim, Mélanie Chevance, J. M. Diederik Kruijssen +33
The earliest stages of star formation, when young stars are still deeply embedded in their natal clouds, represent a critical phase in the matter cycle between gas clouds and young…
PHANGS-JWST First Results: The 21 m Compact Source Population
Hamid Hassani, Erik Rosolowsky, Adam K. Leroy +24
We use PHANGS-JWST data to identify and classify 1271 compact 21 m sources in four nearby galaxies using MIRI F2100W data. We identify sources using a dendrogram-based algorithm…
PHANGS-JWST First Results: Spurring on Star Formation: JWST Reveals Localised Star Formation in a Spiral Arm Spur of NGC 628
