Multiscale Turbulence Synthesis: Validation in 2D Hydrodynamics
Pierre Lesaffre, Jean-Baptiste Durrive, Jean Goossaert +5
Numerical simulations can follow the evolution of fluid motions through the intricacies of developed turbulence. However, they are rather costly to run, especially in 3D. In the pa…

Generative Models of 21cm EoR Lightcones with 3D Scattering Transforms
Ian Hothi, Erwan Allys, Benoit Semelin +1
The 21cm signal from the Epoch of Reionization (EoR) is observed as a three-dimensional data set known as a lightcone, consisting of a redshift (frequency) axis and two spatial sky…

Comparing the morphology of molecular clouds without supervision
Pablo Richard, Erwan Allys, François Levrier +2
Molecular clouds show complex structures reflecting their non-linear dynamics. Many studies investigating the bridge between their morphology and physical properties have shown the…
