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…
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…
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…
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…
