Italy-Japan Research on Gravitational Waves: The Birth of Multi-messenger Astrophysics



Italy-Japan Research on Gravitational Waves: The Birth of Multi-messenger Astrophysics

It was not until September 2015 that gravitational waves were detected, despite their prediction by Albert Einstein a century ago. Their first observation was a milestone that was awarded two years later with the Nobel Prize in Physics. This allowed us to explore the history and structure of our universe, since gravitational waves carry information of the motions of objects in the universe. Furthermore, the increasing detectors’ sensitivity permits the challenge of new scientific problems. Indeed, there is a growing interest in the new field of multi-messenger astrophysics, based on the coordinated observation and interpretation of various messenger signals (including electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays). This seminar aims to describe the basic principles of gravitational waves and how they were detected. Moreover, the present status of advanced detectors and the foreseen evolution towards third-generation detectors will be illustrated, with focus on the Japanese and European collaboration.
