Objectives


The detection of the Gravitational Waves (GW) emitted by a black holes binary on September 14th 2015 has opened a new window on the Universe. The observation of the kilonova explosion on August 17th 2017 through all different electromagnetic, particle and indeed, gravitational probes is worldwide recognized as the first example of Multimessenger Astronomy.

 

France is actively contributing to the project Virgo that is going through a large amelioration of the interferometer regarding laser, optics and quantum techniques. This experimental effort will lead to the new detector called Advanced Virgo +. At the same time the collaboration called Einstein Telescope is preparing the design of the third generation of GW detector in Europe, a generation that will detect GW emitted from all the visible Universe.

GW physics is a rapidly expanding new field and scientists are living in a very similar situation as the one at the dawn of particle physics.

As always when a new field of physics is emerging there is a difficulty to follow what’s happening: fundamental properties of GW, details of their detectors, specific vocabulary, are not in the normal background of a physics student.

This introductory course has been thought to make GW physics more approachable. We are going to familiarize with fundamental properties of GW, description of the GW source, description and status of the detector at the moment of detection, significance of the detection. The last part of the course will be focused on the future developments in the field.

The course is meant for experimental physicists. Although the parts dedicated to the properties of GW, their sources and their effects on the detectors constitute 70% of the
subjects, the approach used here is to show how to use GW as a probe to study the Universe and why this probe is complementary to the electromagnetic one.
