MÉTHODES D’ANALYSE DES DONNÉES

The future LISA detector will complement current ground-based observations of gravitational waves by targeting a lower-frequency band, enabling the detection of supermassive black hole mergers, as well as stellar mass black hole before they reach the LIGO/Virgo band. Much remains to be explored for LISA capabilities to characterize those signals. Using recently developed techniques enabling...

FORMES D’ONDE

Post-Newtonian (PN) calculations constitute a crucial ingredient to build the
waveform models for compact binaries that are used in the data analysis of the
current (and future) gravitational-wave interferometers. For the resulting
templates to be faithful, the overlap of the PN polarisations with their
numerical counterparts must be made as high as possible. This requires to
obtain the...
