Broad-band detection of gravitational waves: ground and space
Rapid identification of electromagnetic counterparts
Interpretation : fundamental physics, cosmology, astrophysics

Participation in three federating projects: VIRGO, LISA, Einstein Telescope

  • Laser instrumentation: stabilisation
  • Space instrumentation: photoreceptors, scattered light, optical benches
  • LISA ground segment, coordination of catalogue creation
  • Contributions to several working groups and key publications of the LVK collaboration (LIGO/Virgo/KAGRA)

Multi-messenger tracking

  • fast telescopes, alert management (GRANDMA)
  • Calern site : TAROT


  • Population of sources (coalescences of black holes and neutron stars), Galactic sources, double supermassive black holes, non-modelled sources, stochastic backgrounds of cosmological and astrophysical origin, cosmology, transient sources, etc.

Gravitational waves : meeting astrophysical challenges

Objectives :

With its instrumental and astrophysical expertise and access to its own site (Plateau de Calern), the OCA is a unique site for the development of gravitational wave science and multimessenger astronomy. We are particularly interested in :

  • Continuing involvement with VIRGO-ET and LISA instruments
  • Extend astrophysical support for the analysis of GW sources
  • Develop observational cosmology in synergy with SKA/LISA/EUCLID​

This research theme receives funding for supervising internships, inviting external scientific experts and organising workshops and schools.

In 2023, we financed :

We were also able to invite a number of researchers.
