Dans le cadre de l’analyse de données de LISA et du développement du pipeline d’alertes rapides (LLAP) qui impose de fortes contraintes de temps, où la détection et la caractérisation rapide des binaires de trous noirs supermassifs (MBHB) constituent un enjeu central, je présenterai mes travaux sur l’estimation de leurs paramètres.
Je montrerai ainsi une approche basée sur une simulation de...

A primary target for LISA will be massive black hole binaries (MBHBs), the inspiral of which will be detectable in a few days to months before coalescence. If they occur in gas-rich environments, they may produce electromagnetic (EM) counterparts, allowing for multimessenger follow-up.

To provide triggers to the EM community rapid parameter estimation is needed, specifically of merger time,... -

Among the numerous sources expected to be observed by LISA, stellar-mass black holes and EMRIs constitute two of the main classes with specific science objectives. The former, already observed by LVK detectors, would be now discovered in their early inspiral phase where, for example, eccentricity information would give us information on the environment in which they form and would give a probe...

Dans le cadre du groupe Performance & Operations, je présenterai une analyse des impacts des simplifications et corrélations au niveau constellation. Deux questions ont guidé ce travail : ces simplifications remettent-elles en cause le budget de bruit, et permettent-elles de conduire une campagne de vérification ? Les résultats montrent que si le budget de bruit reste valide, la vérification...

The French contribution to the LISA Consortium, on the instrumental side, focuses on developing optical ground support equipment to validate LISA's performance prior to launch. One key task of the French community is to test and validate the performance of the Interferometric Detection System (IDS).
To this end, the IDS Test Set-Up is currently under development. Its objectives are twofold:...

The presentation will review the technologies that have been developed during the last year for testing the performances of the metrological instrumentation core of LISA with the Beam Simulator, a test contraption. An introductory part will give a general description of the Beam Simulator, explaining the need at the origin of its development, the test Interferometric Detection System (IDS)...
