The Radial and Vertical Structure of Molecular Gas in the Edge-On Galaxy NGC 4565
Grace Krahm, Adam K. Leroy, Jiayi Sun +11
We present high-resolution (0.94" 55 pc) ALMA CO(2-1) and 13CO(2-1) observations of the highly inclined (i~87.5 deg) galaxy NGC 4565 covering out to galactocentric radius…

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…

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 pred…
