Virial-based extraction of structures in numerical simulations: The vibes tool

Simon Chevalier, Fabien Louvet, Yann Bernard +9

The processes that determine the stellar initial mass function (IMF) and its connection to the core mass function (CMF) are among the major open questions in star formation. The de…

Rhea-RT: Dynamical impact of Central Molecular Zone conditions on the properties of the interstellar medium and stellar feedback coupling

R. G. Tress, N. Brucy, P. Girichidis +22

The Central Molecular Zone (CMZ) is an extreme star formation environment, characterized by higher density, higher turbulence, stronger orbital shear, and stronger magnetic field s…

The slope of the power spectrum of the density field in isothermal supersonic compressible turbulence

Pierre Dumond, Jérémy Fensch, Gilles Chabrier +1

The power spectrum (PS) of the density field in supersonic turbulence is a fundamental quantity that characterizes the statistical properties of the structures formed in compressib…

The diffuse gamma-ray sky of a Milky Way analogue: Local diversity and global constraints

Karin Kjellgren, Philipp Girichidis, Maria Werhahn +8

Diffuse gamma-ray emission is a key tracer of cosmic rays (CRs) in galaxies, encoding information about their transport, energetics, and interactions with the interstellar medium.…

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…

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…
