Astrophysique à Haute Energie

Le satellite SVOM, fruit d’une collaboration de l'agence spatiale française (CNES), chinoise (CNSA) et de l'académie des sciences chinoise (CAS), a été lancé avec succès samedi 22 juin depuis la base de Xichang, en Chine.

PhD position in Neutrino and Multi-Messenger Astronomy

The Astroparticle physics groups hosted at the Centre for Cosmology, Particle Physics and Phenomenology (CP3) at UCLouvain (Belgium) and at the Laboratoire Astroparticule et Cosmologie (APC) at Université Paris Cité (UPCité) are welcoming applications for a joint PhD student position in neutrino and multi-messenger astronomy.

Searching for high-energy neutrino sources with the KM3NeT experiment

The origin of cosmic rays (CRs) with up to 10^20 eV energies is one of the most important questions in astrophysics to date. One way to track down CR sources and study CR propagation is to look for the products of cosmic ray interactions interactions, in particular high-energy (TeV-PeV) neutrinos. These neutrinos, indeed, are characteristic of hadronic interactions and thus would be an unambiguous signature of the presence of cosmic rays.

The first images captured by the innovative mission were presented at the 7th workshop of the Einstein Probe consortium in Beijing. They illustrate the satellite’s full potential and show that its novel optics, which mimic a lobster’s eyes, are ready to monitor the X-ray sky.

Elles illustrent tout le potentiel du satellite et montrent que ses nouvelles optiques, qui imitent les yeux d’un homard, sont prêtes à surveiller le ciel transitoire.

MULTI-MESSENGER ASTRONOMY : STUDY OF EXTREME TRANSIENTS IN GAMMA RAYS AND NEUTRINOS

The thesis will take place within the High Energy Astrophysics (AHE) group of the APC laboratory. APC is at the heart of the development of multi-messenger astronomy of extreme transient phenomena in the Universe.

High-energy particles and relativistic sources in astrophysics

High-energy particles and relativistic sources in astrophysics
Where do cosmic rays, neutrinos and high-energy photons come from? How is
radiation emitted from black hole environments, blazars, gamma-ray bursts and other
relativistic sources? What process gives rise to the electromagnetic counterparts of
gravitational wave events? All these questions shape the rapidly-developing fields of
high-energy astrophysics and multi-messenger astrophysics. At the heart of these
