Astroparticles, Astrophysics and Cosmology (A2C)
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the joint dataset collected by…
Extrait de JAX-COSMO: An End-to-End Differentiable and GPU Accelerated Cosmology Library (https://arxiv.org/abs/2302.05163) We present jax-cosmo, a library for automatically differentiable cosmological theory calculations.jax-cosmo uses the JAX library, which has created…
SVOM is a Sino-French space mission targeting high-energy transient astrophysical objects such as gamma-ray bursts. The soft X-ray part of the spectrum is covered by the Micro-channel X-ray Telescope (MXT)…
On August 8, 2021, a "new" star appeared in the constellation of Ophiuchus and remained visible to the naked eye for several days. In fact, it had already been observed…
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…
