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…
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…
Neural ocean forecasting from sparse satellite-derived observations: a case-study for SSH dynamics and altimetry data

We present an end-to-end deep learning framework for short-term forecasting of global sea surface dynamics based on sparse satellite altimetry data. Building on two state-of-the-ar…
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…
Key role of the Madden-Julian Oscillation on tropical and subtropical humid heat and heatwaves
Claire Rocuet, Takeshi Izumo, Bastien Pagli +4
Humid heat stress and heatwaves pose significant risks for living organisms, from humans and wildlife to insects. These threats have wide-ranging health, ecological, and socio-econ…
A Stochastic Ekman-Stokes Model for Coupled Ocean-Wave-Atmosphere Dynamics
Long Li, Etienne Mémin, Bertrand Chapron
Accurate representation of atmosphere-ocean boundary layers, including the interplay of turbulence, surface waves, and air-sea fluxes, remains a challenge in geophysical fluid dyna…
Phase-resolved modelling of wave transformation in the surf zone over idealised rough bottoms
Emile Guélard-Ancilotti, Damien Sous, Denis Morichon +3
In order to understand and predict coastal flooding processes in rocky environments, it is necessary to take into account bottom roughness, which plays a key role in wave transform…
Phase-resolved Modeling Of Surf Zone Wave Transformation Over Idealized Rough Bottoms
Emile Guélard-Ancilotti, Damien Sous, Denis Morichon +3
Rough rocky seabeds dominate world's coastlines, making accurate modeling of wave transformation in such environments essential for understanding coastal processes and hazards. Wav…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
Towards sustainable space research in France
Alexandre Santerne, Héloïse Meheut, Didier Barret +8
During the 2024's quinquennial scientific roadmap of CNES, a specific group worked on setting recommendations to decrease the environmental footprint of space science activities. T…
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…
Inversion of sea surface currents from satellite-derived SST-SSH synergies with 4DVarNets
Ronan Fablet, Bertrand Chapron, Julien Le Sommer +1
Satellite altimetry is a unique way for direct observations of sea surface dynamics. This is however limited to the surface-constrained geostrophic component of sea surface velocit…
GENESIS: Co-location of Geodetic Techniques in Space
Pacôme Delva, Zuheir Altamimi, Alejandro Blazquez +39
Improving and homogenizing time and space reference systems on Earth and, more directly, realizing the Terrestrial Reference Frame (TRF) with an accuracy of 1mm and a long-term sta…
Two-dimensional structure functions to characterize convective rolls in the marine atmospheric boundary layer from Sentinel-1 SAR images
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier +3
We study the shape of convective rolls in the Marine Atmospheric Boundary Layer from Synthetic Aperture Radar images of the ocean. We propose a multiscale analysis with structure f…
Geometry and kinematics of the broad emission line region in the lensed quasar Q2237+0305
Damien Hutsemékers, Dominique Sluse
Line profile distortions are commonly observed in gravitationally lensed quasar spectra. These distortions are caused by microlensing from the stars in the lensing galaxy, which pr…
SRoll3: A neural network approach to reduce large-scale systematic effects in the Planck High Frequency Instrument maps
Manuel López-Radcenco, Jean-Marc Delouis, Laurent Vibert
In the present work, we propose a neural network based data inversion approach to reduce structured contamination sources, with a particular focus on the mapmaking for Planck High…
