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…
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…
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…
The impact of spiral arms on the star formation life cycle
Andrea Romanelli, Mélanie Chevance, J. M. Diederik Kruijssen +18
The matter cycle between gas clouds and stars in galaxies plays a crucial role in regulating galaxy evolution through feedback mechanisms. In turn, the local and global galactic en…
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…
Introducing the Rhea simulations of Milky-Way-like galaxies I: Effect of gravitational potential on morphology and star formation
Junia Göller, Philipp Girichidis, Noé Brucy +11
The Milky Way is a complex ecosystem, for which we can obtain detailed observations probing the physical mechanisms determining the interstellar medium. For a detailed comparison w…
The dynamical impact of cosmic rays in the Rhea magnetohydrodynamics simulations
Karin Kjellgren, Philipp Girichidis, Junia Göoller +10
This study explores the dynamical impact of cosmic rays (CRs) in Milky Way-like galaxies using the Rhea simulation suite. Cosmic rays, with their substantial energy density, influe…
