The « Galaxies, High Energy, Cosmology, Compact Objects & Stars » (GALHECOS) team studies the formation and evolution of galaxies and our Galaxy in a cosmological context by studying their stellar populations, the dynamics of their stars and of dark matter, and the feedback effects that are linked, in particular, to the activity of their central black hole. The team studies galactic and extragalactic X-ray emitters, compact objects (neutron stars, white dwarfs, etc.) and active galactic nuclei. We are involved in the SSC-XMM, an international consortium of institutes, selected by ESA and approved by CNRS/INSU as a Service d’Observation, that is responsible for providing to the international community complete catalogues of observed X-ray sources observed by the XMM-Newton satellite. The GALHECOS team is also involved in the following Services Nationaux d’Observations: SVOM, Large Spectroscopic Surveys with WEAVE and Gaia, and the Besançon Model of Galaxy.
The team is involved in numerous projects funded at the national (GaDaMa, MWDisc, MORPHER, POPSYCLE, Pristine, SEGAL) and European (GREATDIGINTHESKY, XMM2ATHENA) levels.
