The relation in the multi-phase ISM: Exploring the density PDF with the Cloud Factory simulations
Mairi Nonhebel, Rowan J. Smith, Ralf S. Klessen
The density probability distribution (PDF) of molecular clouds is a crucial component of analytical theories of star formation. In idealised simulations of isothermal turbulence, t…
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 Structure of Molecular Gas in PHANGS-ALMA Galaxies: Cloud Spacing, Two-Point Correlation and Stacked Intensity Profiles
Hao He, Adam Leroy, Erik Rosolowsky +21
The sub-kpc scale gas structure encodes key information of giant molecular cloud (GMC) formation. Therefore, we aim for a quantitative description of molecular gas structure across…
How is cold, star-forming gas in galaxies affected by magnetic fields?
Kamran R. J. Bogue, Rowan J. Smith, Robin G. Tress +9
Numerical simulations provide a unique opportunity to improve our understanding of the role of magnetic fields in the interstellar medium of galaxies and in star formation. However…
A bottleneck for star formation: the importance of magnetic fields during the formation of cold gas in galaxies
Ryan McGuiness, Rowan J. Smith, David Whitworth
Using a high-resolution simulation of a dwarf galaxy, we quantify the energetic importance of magnetic fields within the different phases of its interstellar medium (ISM) on parsec…
The role of turbulence in setting the phase of the ISM and implications for the star formation rate
Tine Colman, Patrick Hennebelle, Noé Brucy +10
In this work, we explore the link between star formation, turbulence and the thermal state of the multi-phase ISM. We analyse a suite of stratified box simulations modelling a real…
