Since 2019, Laura Bernard has been a CNRS research fellow at the Laboratoire Univers et Théorie (LUTh) at Observatoire de Paris - PSL.
Gravitational waveform expert...
On the one hand, Laura Bernard’s research aims to model gravitational waves using alternative theories of gravity.
Her work has earned her recognition as a specialist in gravitational waveforms in tensor-scalar extensions of general relativity.
In particular, she has demonstrated a new tidal effect due to the scalar field in the evolution of binary systems of compact objects.
Knowledge of waveforms in tensor-scalar theories is crucial for testing gravitation via current (LIGO, Virgo and KAGRA) and future (LISA, Einstein Telescope and Cosmic Explorer) gravitational wave detectors - tensor-scalar theories being the most natural alternative to general relativity.
These results are now in the process of being put to direct use in preparation for the operation of the LISA space mission, and of the future ground-based interferometer, the Einstein Telescope, with a complete waveform data bank, covering the widest possible parameter space - masses, spins, eccentricities, etc. - in which to work. - as large as possible.
...in search of alternatives to general relativity
In parallel with these phenomenological activities, Laura Bernard is also studying more fundamental aspects of alternatives to general relativity.
In this context, she has been investigating problems such as environmental effects around binary systems, resonances and chaos around a perturbed Kerr black hole.
On each of these subjects, Laura Bernard’s work has led to significant advances, adopting analytical or semi-analytical methods. This has also made it possible to bypass the numerical difficulties that can be encountered in a numerical resolution of the complete Einstein equations, as well as promoting numerical sobriety.
and resolutely committed
The SF2A Board, in addition to considering the advances made by her work, noted Laura Bernard’s sense of commitment, as she has not hesitated to take on numerous scientific and institutional responsibilities at local, national, European and international levels since the start of her career.
The Board also appreciated her commitment to mentoring young researchers.
