Azimuthal offsets in spiral arms of nearby galaxies
Miguel Querejeta, Sharon E. Meidt, Yixian Cao +28
Spiral arms play a central role in disc galaxies, but their dynamical nature remains a long-standing open question. Azimuthal offsets between molecular gas and star formation are e…
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…
Time-scales of polycyclic aromatic hydrocarbon and dust continuum emission from gas clouds compared to molecular gas cloud lifetimes in PHANGS-JWST galaxies
Jaeyeon Kim, Mélanie Chevance, Lise Ramambason +24
Recent JWST mid-infrared (mid-IR) images, tracing polycyclic aromatic hydrocarbons (PAHs) and dust continuum emission, provide detailed views of the interstellar medium (ISM) in ne…
Reconciling extragalactic star formation efficiencies with theory: insights from PHANGS
Sharon E. Meidt, Simon C. O. Glover, Ralf S. Klessen +22
New extragalactic measurements of the cloud population-averaged star formation (SF) efficiency per freefall time from PHANGS show little sign of theoretically predi…
The impact of spiral arms on the star formation life cycle
Andrea Romanelli, Mélanie Chevance, J. M. Diederik Kruijssen +18
The matter cycle between gas clouds and stars in galaxies plays a crucial role in regulating galaxy evolution through feedback mechanisms. In turn, the local and global galactic en…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN) II: Survey design and observations
K. Sophia Stuber, Jerome Pety, Antonio Usero +18
We present Surveying the Whirlpool at Arcseconds with NOEMA (SWAN), a high-resolution, high-sensitivity survey to map molecular lines in the 3mm band in M51 (the Whirlpool galaxy).…
Cloud-scale gas properties, depletion times, and star formation efficiency per free-fall time in PHANGS--ALMA
Adam K. Leroy, Jiayi Sun, Sharon Meidt +31
We compare measurements of star formation efficiency to cloud-scale gas properties across PHANGS-ALMA. Dividing 67 galaxies into 1.5 kpc scale regions, we calculate the molecular g…
