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,…
Article: Impact of Galaxy clusters on UHECR propagation
By Antonio Condorelli a, Jonathan Biteau a,b, Remi Adamc a Université Paris-Saclay, CNRS/IN2P3, IJCLab, 91405 Orsay, France b Institut universitaire de France (IUF) c Université Côte d’Azur, Observatoire de la…
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…
Article: Multiwavelength analysis of Galactic Supernova Remnants
The photon spectrum of HESS J1731-347 fitted by using the lepto-hadronic model. By P. Sharmaa, Z. Oub, C. Henry-Cadrota, C. Dubosa and T. Suomijärvia aUniversité Paris-Saclay, CNRS/IN2P3, IJCLab, 91405 Orsay,…
Deep multimessenger search for compact binary mergers in LIGO, Virgo and Fermi/GBM data from 2016-2017
GW170817 - GRB 170817A provided the first observation of gravitational waves from a neutron star merger with associated transient counterparts across the entire electromagnetic spectrum. This discovery demonstrated the long-hypothesized…
Recent advances toward mesoscopic quantum optomechanics
We present a number of approaches, currently in experimental development in our research groups, toward the general problem of macroscopic quantum mechanics, i.e., manifestations of quantum noise and quantum fluctations…
