The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies
Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29
We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…
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…
Localized Deviations from the CO-PAH Relation in PHANGS-JWST Galaxies: Faint PAH Emission or Elevated CO Emissivity?
Jaeyeon Kim, Adam K. Leroy, Karin Sandstrom +25
Polycyclic aromatic hydrocarbon (PAH) emission is widely used to trace the distribution of molecular gas in the interstellar medium, exhibiting a tight correlation with CO(2-1) emi…
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…
Resolved HII regions in NGC 253: Ionized gas structure and suggestions of a universal density-surface brightness relation
Rebecca L. McClain, Adam K. Leroy, Enrico Congiu +23
We use the full-disk VLT-MUSE mosaic of NGC 253 to identify 2492 HII regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the la…
Resolved Profiles of Stellar Mass, Star Formation Rate, and Predicted CO-to-H Conversion Factor Across Thousands of Local Galaxies
Jiayi Sun, Yu-Hsuan Teng, I-Da Chiang +9
We present radial profiles of surface brightness in UV and IR bands, estimate stellar mass surface density () and star formation rate surface density (),…
