Generative Models of Multi-channel Data from a Single Example -- Application to Dust Emission
Bruno Régaldo-Saint Blancard, Erwan Allys, Constant Auclair +5
The quest for primordial -modes in the cosmic microwave background has emphasized the need for refined models of the Galactic dust foreground. Here, we aim at building a realist…
Non-Gaussian modelling and statistical denoising of Planck dust polarization full-sky maps using scattering transforms
J. -M. Delouis, E. Allys, E. Gauvrit +1
Scattering transforms have been successfully used to describe dust polarization for flat-sky images. This paper expands this framework to noisy observations on the sphere with the…
Wavelet Moments for Cosmological Parameter Estimation
Michael Eickenberg, Erwan Allys, Azadeh Moradinezhad Dizgah +10
Extracting non-Gaussian information from the non-linear regime of structure formation is key to fully exploiting the rich data from upcoming cosmological surveys probing the large-…
Quantification of high dimensional non-Gaussianities and its implication to Fisher analysis in cosmology
Core Francisco Park, Erwan Allys, Francisco Villaescusa-Navarro +1
It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been…
