Fabien Cavalier, CNRS research Director, will address the Science Diplomats Club on Wednesday, October 18, 2017 from 8am to 10am, at the Embassy of France in Washington, DC.

About the speaker

Fabien Cavalier is a CNRS research Director at the Laboratoire de l’Accélérateur Linéaire (LAL, CNRS/Université Paris-Sud), in Orsay. In the Virgo experiment, his activities have always been based on two major subjects: longitudinal control of optical cavities (Virgo at Cascina and CALVA test bench at LAL) and data analysis (characterization of the detector and search for unmodeled short signals). He was in charge of Virgo global control and data analysis coordinator. He is currently a member of the detection committee. In addition to these scientific activities, since February 2011, he has been the deputy director of LAL (300 people including 100 researchers).

About the observations of gravitational waves

The 2017 Nobel Prize in Physics was just awarded to researchers who detected for the first time a gravitational wave produced in 2015 by the fusion of two black holes.

Advanced LIGO gravitational wave detectors then carried out their second data collection phase from December 2016 to August 2017 and during the same period, the European detector Advanced Virgo started operating. The two detectors were therefore able to collect common data for a few fruitful weeks in August 2017.

Fabien Cavalier will present the observations made during this most recent data collection which will allow us to shed new light on General Relativity and some violent astrophysical phenomena.
