"The replication supports the generalisation claim of Delouis et al. 2022 — that the scattering-transform framework on the HEALPix sphere applies beyond Planck dust polarisation to other astrophysical processes. Using the authors' own FOSCAT software, scattering synthesis from random noise produces a new cosmological large-scale-structure map whose multi-scale statistics match those of the target input. The framework generalises, at least to one additional astrophysical case." . . "Scattering-transform synthesis applied to a cosmological LSS map (LSS_map_nside128.npy from FOSCAT_DEMO, downgraded to nside=32) starting from random noise, 300 L-BFGS iterations, NORIENT=4, KERNELSZ=3, on CPU (143 seconds, Apple M1 Pro):\n \n- Power spectrum ratio (synthesised / target, mean across multipoles): 0.987 — close to the ideal 1.0\n- Scattering coefficient improvement: 99.55% — synthesis converges to near-target scattering statistics \n- Pixel-level correlation (synthesised vs target): −0.0038 — close to zero, as expected when the synthesis produces a new realisation rather than copying \n- Distributional match: target mean ≈ 0, std = 0.739; synthesised mean ≈ 0, std = 0.746 — distributions match to within rounding\n \nFull results JSON and figure archived at Zenodo 10.5281/zenodo.19685025. \nGithub repository: https://github.com/annefou/fiesta-scattering-astro" . "Three caveats limit the strength of the conclusion: \n \n1. Single realisation. The synthesis was run once with a fixed random seed; no variance estimate across multiple realisations is available. \n2. Lower resolution than the paper. This study runs at nside=32 (12,288 pixels) for CPU compatibility; the original paper uses nside=256. \n3. Demonstration-grade input data. The cosmological LSS map is a single demo artefact distributed in the FOSCAT_DEMO repository, not a peer-reviewed scientific dataset, and it is not the data the original paper is about (Planck 353 GHz dust polarisation). A future study could test the framework on multiple peer-reviewed astrophysical datasets at the paper's native resolution to strengthen the generalisation evidence. " . . . . . "Anne Fouilloux" .
