Proposal Ground-based detectors have been directly detecting gravitational waves since 2015. Their outstanding performances are allowed by improvement with respect to the basic operating principle of the Michelson interferometer. Suspended…
Supervisors Julien Peloton: <peloton@ijclab.in2p3.fr> Jonathan Biteau: <biteau@in2p3.fr> Proposal A blazar is an active galactic nucleus (AGN) whose relativistic jet is directed nearly along the line of sight. This jet emits…
4D mapping of blazars: from optical to ɣ-ray emission 4D mapping of blazars:from optical to ɣ-ray emission 4D mapping of blazars: from optical to ɣ-ray emission 4D mapping of blazars:…
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…
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…
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…
AugerPrime detector with the SSD and RD atop the WCD.The station electronics is hidden underneath the dome visible on top of the WCD. Operating since 2004, the Pierre Auger Observatory…
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,…
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…
