Cloud properties across spatial scales in simulations of the interstellar medium
Tine Colman, Noé Brucy, Philipp Girichidis +9
Molecular clouds (MC) are structures of dense gas in the interstellar medium (ISM), that extend from ten to a few hundred parsecs and form the main gas reservoir available for star…
Inefficient star formation in high Mach number environments II. Numerical simulations and comparison with analytical models
Noé Brucy, Patrick Hennebelle, Tine Colman +2
Predicting the star formation rate (SFR) in galaxies is crucial to understand their evolution and morphology. To do so requires a fine understanding of how dense structures of gas…
Large-scale turbulent driving regulates star formation in high-redshift gas-rich galaxies II: Influence of the magnetic field and the turbulent compressive fraction
Noé Brucy, Patrick Hennebelle, Tine Colman +1
The observed star formation rate (SFR) in galaxies is well below what it should be if gravitational collapse alone were at play. It has recently been shown that one candidate that…
EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale
Nitin Shukla, Alessandro Romeo, Caterina Caravita +36
High Performance Computing (HPC) based simulations are crucial in Astrophysics and Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena. T…
What is the contribution of gravitational infall on the mass assembly of star-forming clouds? A case study in a numerical simulation of the interstellar medium
Noé Brucy, Enrique Vázquez-Semadeni, Tine Colman +2
Star formation in galaxies is a complex phenomenon occurring on a very wide range of scales, and molecular clouds are at the heart of this process. The formation of these structure…
On the origin of the peak of the stellar initial mass function: exploring the tidal screening theory
Tine Colman, Romain Teyssier
Classical theories for the stellar initial mass function (IMF) predict a peak mass which scales with the properties of the molecular cloud. In this work, we explore a new theory pr…
Stellar Feedback in the Star Formation-Gas Density Relation: Comparison between Simulations and Observations
Paolo Suin, Annie Zavagno, Tine Colman +3
Context. The impact of stellar feedback on the Kennicutt-Schmidt law (KS law), which relates star formation rate (SFR) to surface gas density, is a topic of ongoing debate. The int…
The signature of large scale turbulence driving on the structure of the interstellar medium
Tine Colman, Jean-François Robitaille, Patrick Hennebelle +9
The mechanisms that maintain turbulence in the interstellar medium (ISM) are still not identified. This work investigates how we can distinguish between two fundamental driving mec…
Protoplanetary disk birth in massive star forming clumps: the essential role of the magnetic field
Ugo Lebreuilly, Patrick Hennebelle, Tine Colman +5
Protoplanetary disks form through angular momentum conservation in collapsing dense cores. In this work, we perform the first simulations with a maximal resolution down to the astr…
Are supernovae driving turbulence in the solar neighborhood?
Georges Abboudeh, Patrick Hennebelle, Juan D. Soler +9
Turbulence plays an important role in shaping the interstellar medium, and strongly influences star formation. We aim to identify the physical processes capable of sustaining HI tu…
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…
Inefficient star formation in high Mach number environments I. The turbulent support analytical model
Patrick Hennebelle, Noé Brucy, Tine Colman
The star formation rate (SFR), the number of stars formed per unit of time, is a fundamental quantity in the evolution of the Universe. While turbulence is believed to play a cruci…
How magnetic field and stellar radiative feedback influences the collapse and the stellar mass spectrum of a massive star forming clump
Patrick Hennebelle, Ugo Lebreuilly, Tine Colman +10
In spite of decades of theoretical efforts, the physical origin of the stellar initial mass function (IMF) is still debated. We aim at understanding the influence of various physic…
