Detecting gravitational waves with Virgo: Nicolas Arnaud explains
Detecting gravitational waves requires managing a lot of data, and being able to find the signal among all the noise affecting the detector. How does the Virgo team achieve this…

IN2P3, 50 years: presentation of A2C
IN2P3 celebrated its 50 years birthday on Apr. 14, 2021. Many events were organized by the IN2P3 laboratories. At IJCLab, the activities of the A2C pole were presented . See…
Improved limits on the tensor-to-scalar ratio using BICEP and Planck
We present constraints on the tensor-to-scalar ratio r using a combination of BICEP/Keck 2018 and Planck PR4 data allowing us to fit for r consistently with the six parameters of…
Test Measurements with the CTA-NectarCAM SPE Calibration system
The NectarCAM camera, with its single photoelectron calibration system (white target in the bottom-right corner) At IJCLab, we are involved in producing the Single Photo-Electron (SPE) calibration system for NectarCAM…

Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3b
We search for gravitational-wave signals associated with gamma-ray bursts detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced LIGO and Advanced…
GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of the Third Observing Run
The LIGO and Virgo detectors have observed 35 new gravitational-wave events, between November 2019 and March 2020, during the second half of the third observing run (O3b). The total number…
