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
Interpretation
- 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.
Responsibility of the SNO AN03 VIRGO
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 :
- 2 master's courses (one on the photometric calibration of ASTEP with a view to its use for transient skies, and one for the analysis of LISA data)
- Participation in the MaNiTou summer school on gravitational waves, which took place in Nice in July
- The organisation of a workshop on the creation of LISA mission catalogues
- A workshop on the science of AGNs, including double AGNs.
We were also able to invite a number of researchers.
