Revealing Galactic dust beneath the cosmic infrared background anisotropies with Wavelet Phase Harmonics
Srijita Sinha, Tuhin Ghosh, Erwan Allys +2
Separating Galactic dust emission from cosmic infrared background (CIB) anisotropies is challenging because both the emission components have similar spectral properties. The prima…

Untangling dust emission and cosmic infrared background anisotropies with the scattering transform statistics
Srijita Sinha, Tuhin Ghosh, Erwan Allys +2
The template-fit approach is often used to separate Galactic dust emission from cosmic infrared background (CIB) anisotropies in low column density regions, under the a…

A filtered multilevel Monte Carlo method for estimating the expectation of cell-centered discretized random fields
Jérémy Briant, Paul Mycek, Mayeul Destouches +5
In this paper, we investigate the use of multilevel Monte Carlo (MLMC) methods for estimating the expectation of discretized random fields. Specifically, we consider a setting in w…
