Welcome to the pages of the GECO group

The Galaxies, Etoiles et Cosmologie (GECO; Galaxies, Stars, and Cosmology) group covers a wide range of topics going from stars to cosmology. In particular it covers the study of:

  • the interstellar and intergalactic media,
  • the different phases of the formation of stars,
  • the physical processes involved in the formation and the evolution of galaxies and their environment,
  • the dynamics of galaxies,
  • the large-scale structure of the Universe,
  • the dark matter properties,
  • the cosmological model.



  • On-going calls for telescope time, grants, travel money, positions, conf/workshop registrations (pertinent to the team).
