4. Pour une approche historico-linguistique des documents historiques. Croisements inter/transdisciplinaires en France et en Italie

Journal of Interdisciplinary History of Ideas, 2016
Depuis quelques années désormais, nous nous sommes penchées sur la possibilité de croiser les méthodes linguistiques avec celles de l’histoire dans l’effort d’interroger les documents historiques de deux observatoires complémentaires (interdisciplinarité)

Multiple Reconnection X‐Lines at the Earth's Magnetopause in the Presence of Magnetosheath Flow

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Magnetic reconnection occurs continuously along long X‐lines at the Earth's magnetopause. The maximum magnetic shear model predicts the locations of these long X‐lines for a wide range of upstream solar wind conditions. One of the more perplexing observational results is that these X‐lines appear to be stationary, even in the presence of ...

Un observatoire parmi les lieux d’observation du ciel : le projet de l’Observatoire royal de Louis XIV au prisme de son nom

Cahiers d’histoire, 2017
Qu’est-ce qu’un observatoire ? Quels furent les premiers observatoires de l’histoire ? Dans cette étude, nous montrerons que le choix du nom « observatoire » pour l’Observatoire royal de Paris, fondé pour Louis XIV et pour l’Académie royale des sciences,

Fault Roughness Controls Seismicity Front Migration During Fluid Injection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The increasing occurrence of injection‐induced earthquakes has raised public concern and highlighted the importance of understanding subsurface processes and mechanisms to assess induced seismic hazards and risks. We develop a simple physics‐based model to investigate how fault roughness controls the migration of seismicity during fluid ...

Machine Learning‐Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Nowcasting and forecasting of the radiation environment in the Earth's lower atmosphere are critical for the safety of aircraft and spacecraft crews and passengers. Currently, this problem is addressed by employing statistical and physics‐based models that take into account particle transport and precipitation.

Kinetic Structure of an Interplanetary Shock Observed at Two Heliocentric Longitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Collisionless shocks convert bulk flow energy into heat, electromagnetic fields, and non‐thermal particle populations. Recent studies suggest that downstream magnetic oscillations could play an important role in ion‐scale energy dissipation at low‐Mach‐number shocks; however, the specific shock and plasma parameters involved remain poorly ...

Spectral Properties and Energy Injection in Mercury's Magnetotail Current Sheet

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Mercury's magnetotail hosts a thin and highly dynamic current sheet (CS), where magnetic reconnection and strong fluctuations frequently occur. Here, we statistically analyze magnetic field power spectra across 370 magnetotail CSs observed by MESSENGER.

Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...
