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
Takashi Yamamoto, Nario Kuno, Daisuke Iono +5
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(…
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…
