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…

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 (),…

The Resolved Behavior of Dust Mass, Polycyclic Aromatic Hydrocarbon Fraction, and Radiation Field in ~ 800 Nearby Galaxies
Jérémy Chastenet, Karin M. Sandstrom, Adam K. Leroy +8
We present resolved m dust spectral energy distribution (SED) fitting for nearby galaxies. We measure the distribution of radiation field intensities heating…
