Statistical description of dust polarized emission from the diffuse interstellar medium -- A RWST approach
Bruno Regaldo-Saint Blancard, François Levrier, Erwan Allys +2
The statistical characterization of the diffuse magnetized ISM and Galactic foregrounds to the CMB poses a major challenge. To account for their non-Gaussian statistics, we need a…

New Interpretable Statistics for Large Scale Structure Analysis and Generation
E. Allys, T. Marchand, J. -F. Cardoso +3
We introduce Wavelet Phase Harmonics (WPH) statistics: interpretable low-dimensional statistics that describe 2D non-Gaussian fields. These statistics are built from WPH moments, w…

The RWST, a comprehensive statistical description of the non-Gaussian structures in the ISM
E. Allys, F. Levrier, S. Zhang +5
The interstellar medium (ISM) is a complex non-linear system governed by gravity and magneto-hydrodynamics, as well as radiative, thermodynamical, and chemical processes. Our under…
