We need to study the Universe at different scales to explain the genesis and evolution of cosmic phenomena from the first cosmological processes to present day stars and galaxies.

The probes we used need to be adapted to the corresponding space scales and each probe studies the cosmological process at different times and depths of interaction. Deployed together, they are a “cosmological piano” for studying the Universe at different frequencies and, consequently, at different energies and distance scales.

The comparison of results produced deepens our knowledge and sometimes hints at the existence of new phenomena!
