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…
Suppression of star formation at the centre of barred AGN galaxies

We measured the Concentration (C) index of Hαand CO (J = 2-1) in 17 nearby star-forming galaxies from the PHANGS survey. We have found four barred spiral galaxies with a C(Hα)/C(CO…
From gas to stars along the spiral wave: CO, HCN, and star formation variations across the spiral arms in NGC 4321 and M51
Minou Greve, Lukas Neumann, Mallory Thorp +17
Molecular clouds form stars from the interstellar medium via gravitational collapse, following a sequence from low-density gas to high-density cores and eventually the formation of…
The lifetime of 100,000 molecular clouds in the nearby Universe
Z. Bazzi, M. I. N. Kobayashi, D. Colombo +25
Multiple mechanisms are proposed for the formation of giant molecular clouds (GMCs), from gravitational free-fall caused by self-gravity to stellar feedback-driven gas compression.…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN). IV. Extent of active galactic nucleus feedback on the interstellar medium
Mallory D. Thorp, Antonio Usero, Frank Bigiel +19
Active Galactic Nuclei (AGN) are intertwined with galaxy evolution, injecting energy into the interstellar medium (ISM) that could regulate star formation as a galaxy evolves. Howe…
NEATH V: the relationship between line emission from dense gas tracers and the star formation rate
F. D. Priestley, P. C. Clark, S. C. O. Glover +5
The Gao-Solomon relationship between the luminosity of the HCN line and the star formation rate (SFR) is observed to remain close to linear over scales ranging from individ…
Molecular Gas Morphological Analogues for the Milky Way
Neal J. Evans, Davide Elia, Keith Hawkins +2
Complete catalogs of molecular clouds in the Milky Way allow analysis of the molecular medium and the star formation properties of the Milky Way that closely follows the method use…
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…
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…
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…
