A steep mass transition for bar-driven ISM structuring revealed by PHANGS-JWST

Eric Emsellem, Jessica Sutter, Ryan Chown +26

Galactic bars play a critical role in the secular evolution of their hosts by reorganising the ISM. We use a sample of 57 star-forming disc galaxies observed with JWST at 3 and 7.7…

Molecular gas and star formation in central rings across nearby galaxies

Damian R. Gleis, Sophia K. Stuber, Eva Schinnerer +20

Nearby galaxies exhibit a variety of structures, including central rings, similar to the MW Central Molecular Zone (CMZ). These rings are common in barred galaxies and can be gas-r…

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 SWAN view of dense gas in the Whirlpool -- A cloud-scale comparison of N2H+, HCO+, HNC and HCN emission in M51

Sophia K. Stuber, Eva Schinnerer, Antonio Usero +22

Tracing dense molecular gas, the fuel for star formation, is essential for the understanding of the evolution of molecular clouds and star formation processes. We compare the emiss…

Simulating nearby disc galaxies on the main star formation sequence II. The gas structure transition in low and high stellar mass discs

Pierrick Verwilghen, Eric Emsellem, Florent Renaud +14

Recent hydrodynamical simulations of isolated barred disc galaxies have suggested a structural change in the distribution of the interstellar medium (ISM) around a stellar mass M$_…

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…

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…

Dynamical resonances in PHANGS galaxies

Marina Ruiz-García, Miguel Querejeta, Santiago García-Burillo +13

Bars are remarkable stellar structures that can transport gas toward centers and drive the secular evolution of galaxies. In this context, it is important to locate dynamical reson…

Azimuthal Variations of Stellar Populations in Barred Galaxies

Justus Neumann, Daniel Thomas, Claudia Maraston +4

Bars are expected to impact the distribution of stellar populations both during bar formation, as they rearrange stars into new orbits, and afterwards, due to the redistribution of…
