Upper limits on diffuse photon fluxes for several energy thresholds, and expected fluxes from UHECRs interactions with the gas distribution in the Galaxy (grey dashed and blue dashed-dotted lines), as…
Illustration of gamma-ray propagation from a blazar at luminosity distance d = 1 Gpc (redshift z ~ 0.2) to the Milky Way. The journal Galaxies published on 22 February 2022…
Abstract: Sources of geophysical noise (such as wind, sea waves and earthquakes) or of anthropogenic noise impact ground-based gravitational-wave interferometric detectors, causing transient sensitivity worsening and gaps in data taking.…
We present our follow-up observations with GRANDMA of transient sources revealed by the Zwicky Transient Facility (ZTF). Over a period of six months, all ZTF alerts were examined in real…
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 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…
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…
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…
The A2C pole will meet on December the 1st for a moment of scientific exchanges at the P. Lehman amphitheatre. This meeting (named L'Univers du pôle A2C: première rencontre) will…
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…
