Astroparticles, Astrophysics and Cosmology (A2C)
Vincent Tatischeff, research director (A2C pole, Astrophysics & Cosmochemistry), was rewarded with the CNRS silver medal, given by Vincent Poireau (IN2P3 DAS), in the presence of Sophie Henrot-Versillé, A2C director.…
Energy flux of ultra-high energy cosmic rays at the Earth as a function of energy. The spectrum of all particles and the proton component are represented by black circles and…
Flux map at energies above 40 EeV with a top-hat smoothing radius of 25° in Galactic coordinates. The supergalactic plane is shown as a gray line. The blank area is…
A specialist in high energy astrophysical phenomena, Vincent Tatischeff is the Director of Research at the Physics of two infinites – Irène Joliot-Curie laboratory (IJCLab – Université Paris-Saclay, Université Paris-Cité,…
Upper limits at 95\% C.L. on the effective coupling constant of a hidden gauge interaction as a function of the mass of a dark matter particle X decaying into quark/anti-quark…
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…
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…
