JWST imaging of the Pleiades: anisotropy of turbulence in the cold neutral medium
G. Vigoureux, N. Flagey, F. Boulanger +14
Interstellar medium studies rely on magnetohydrodynamic (MHD) turbulence as a framework for interpretation. In this context, the statistical characterization of interstellar observ…
Variance of dust temperature and spectral index in Planck polarization data using spin-moment expansion
Vincent Guillet, Léo Vacher, Jonathan Aumont +4
Thermal dust is the major polarized foreground hindering the detection of primordial cosmic microwave background (CMB) B-modes. Its signal exhibits complex behavior in frequency sp…
From few to many maps: A fast map-level emulator for extreme augmentation of CMB systematics datasets
P. Campeti, J. -M. Delouis, L. Pagano +3
We introduce a novel, fast, and efficient generative model built upon scattering covariances, the most recent iteration of the scattering transforms statistics. This model is desig…
Generative models of astrophysical fields with scattering transforms on the sphere
Louise Mousset, Erwan Allys, Matthew A. Price +4
Scattering transforms are a new type of summary statistics recently developed for the study of highly non-Gaussian processes, which have been shown to be very promising for astroph…
