Masses, Star-Formation Efficiencies, and Dynamical Evolution of 18,000 HII Regions
Debosmita Pathak, Adam K. Leroy, Ashley. T. Barnes +36
We present measurements of the masses associated with HII regions across 19 nearby star-forming galaxies by combining data from JWST, HST, MUSE, ALMA, VLA, and MeerKAT…
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…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN): III. CO/CO ratio variations across the M51 galaxy
Ina Galić, Mallory Thorp, Frank Bigiel +16
CO isotopologues are common tracers of the bulk molecular gas in extragalactic studies, providing insights into the physical and chemical conditions of the cold molecular gas, a re…
The vertical structure of the stellar disk in NGC 551
Harshal Raut, Narendra Nath Patra, Prerana Biswas +6
We self-consistently determine the 3D density distribution of NGC 551's stellar disk and study observational signatures of two-component stellar disks. Assuming baryonic disks are…
Extreme cloud collisions in nearby barred galaxies
Tutku Kolcu, Mattia C. Sormani, Witold Maciejewski +16
The inner regions of the Milky Way are known to contain an enigmatic population of prominent molecular clouds characterised by extremely broad lines. The physical origin of these '…
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 resolved star-formation efficiency of early-type galaxies
Thomas G. Williams, Francesco Belfiore, Martin Bureau +19
Understanding how and why star formation varies between galaxies is fundamental to our comprehension of galaxy evolution. In particular, the star-formation efficiency (SFE; star-fo…
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…
