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…
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 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…
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 '…
The Hierarchical Dynamical State of Molecular Gas from 3 to 300 pc in NGC 253
Elias K. Oakes, Christopher M. Faesi, Erik Rosolowsky +25
Understanding how the dynamical state of the interstellar medium (ISM) changes across spatial scales can provide important insights into how the gas is organized and ultimately col…
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$_…
Estimating the dense gas mass of molecular clouds using spatially unresolved 3 mm line observations
Antoine Zakardjian, Annie Hughes, Jérôme Pety +28
We aim to develop a new method to infer the sub-beam probability density function (PDF) of H2 column densities and the dense gas mass within molecular clouds using spatially unreso…
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).…
Dense gas scaling relations at kiloparsec scales across nearby galaxies with the ALMA ALMOND and IRAM 30m EMPIRE surveys
Lukas Neumann, Maria J. Jimenez-Donaire, Adam K. Leroy +17
Dense, cold gas is the key ingredient for star formation. Over the last two decades, HCN(1-0) emission has been utilised as the most accessible dense gas tracer to study external g…
