Galaxies, Astrophysique des Hautes Energies et Cosmologie
Head : Natalie Webb - Deputy : Thierry Contini
The research group "Galaxies, Astrophysique des Hautes Energies et Cosmologie" (Galaxies, High Energy Astrophysics and Cosmology) studies the most violent phenomena and the most extreme processes in the Universe through observation, numerical simulation and theory. The main goal is to understand the physical laws which rule them. The present GAHEC subjects of interest are formation and evolution of the first stars and galaxies, building of galaxies in large-scale structures, dark energy, compact objects (neutron stars and black holes), heavy element enrichment of the interstellar medium during supernova explosions, electron-positron annihilation, and acceleration of cosmic rays. For these studies GAHEC also strongly relies on instrument design for the biggest ground (VLT spectrograph MUSE, HESS, CTA observatory, and in the future instrumentation for ELTs) and space (INTEGRAL, XMM-Newton, FERMI, and in the future SVOM, SPICA and IXO) observatories.
