Short-Term Turbulence Prediction for Seeing Using Machine Learning
Mary Joe Medlej, Rahul Srinivasan, Simon Prunet +2
Optical turbulence, driven by fluctuations of the atmospheric refractive index, poses a significant challenge to ground-based optical systems, as it distorts the propagation of lig…
Towards the Giant Radio Array for Neutrino Detection (GRAND): the GRANDProto300 and GRAND@Auger prototypes
GRAND Collaboration, Jaime Ãlvarez-Muniz, Rafael Alves Batista +118
The Giant Radio Array for Neutrino Detection (GRAND) is a proposed multi-messenger observatory of Ultra-High-Energy (UHE) particles of cosmic origin. Its main goal is to find the l…
Diffusion models for polarimetric reconstruction of circumstellar environments
Quentin Villegas, Laurence Denneulin, Simon Prunet +5
In this paper, we propose an approach combining diffusion models and inverse problems for the reconstruction of circumstellar disk images. Our method builds upon the Rhapsodie fram…
The Giant Radio Array for Neutrino Detection (GRAND) Collaboration -- Contributions to the 39th International Cosmic Ray Conference (ICRC 2025)
Jaime Ãlvarez-Muñiz, Rafael Alves Batista, Aurélien Benoit-Lévy +133
The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles of cosmic origin, with energies in excess of 100 PeV. GRAND uses la…
Reconstruction of inclined extensive air showers using radio signals: from arrival times and amplitudes to direction and energy
Marion Guelfand, Valentin Decoene, Olivier Martineau-Huynh +4
Radio detection is now an established technique for the study of ultra-high-energy (UHE) cosmic rays with energies above eV. The next-generation of radio experiments…
Analytical planar wavefront reconstruction and error estimates for radio detection of extensive air showers
Arsène Ferrière, Simon Prunet, Aurélien Benoit-Lévy +3
When performing radio detection of ultra-high energy astroparticles, the planar wavefront model is often used as a first step to evaluate the arrival direction of primary particles…
