The SVOM launch is a success!
The SVOM satellite took off on June 22, 2024 at 09:00 (Paris time). The launch was successful and the satellite was well positioned on its orbit. First data are expected…
Astroparticles, Astrophysics and Cosmology (A2C)
Article: Floor of cosmogenic neutrino fluxes above 10^17 eV
Figure : Energy flux of neutrinos (single flavor) expected from cosmic-ray interactions in the milky way (“Milky Way”) compared to those from the minimal model of cosmic rays escaping from…
Article: Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory
By APHE Auger group et al. (Pierre Auger Collaboration) One intriguing aspect of the Standard Model (SM) of particle physics is the absence of right-handed degrees of freedom to describe…
Paper: Resonant behavior and stability of a linear three-mirror cavity
Abstract: The implementation of Fabry-Perot cavities in gravitational-wave detectors has been pivotal to improving their sensitivity, allowing the observation of an increasing number of cosmological events with higher signal-to-noise ratio.…
Optimizing the low-latency localization of gravitational waves
Abstract: Gravitational-wave data from interferometric detectors like LIGO, Virgo and KAGRA is routinely analyzed by rapid matched-filtering algorithms to detect compact binary merger events and rapidly infer their spatial position,…

Cosmological parameters derived from the final (PR4) Planck data release
We present constraints on cosmological parameters using maps from the last Planck data release (PR4). In particular, we detail an upgraded version of the cosmic microwave background likelihood, HiLLiPoP, based…
Multi-band analyses of the bright GRB 230812B and the associated SN2023pel
ABSTRACT: GRB 230812B is a bright and relatively nearby (z=0.36) long gamma-ray burst that has generated significant interest in the community and therefore has been subsequently observed over the entire…
A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run
We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate events identified during the third observing run of…
