Gravitational words

Friday, 26. February 2016

On February 11th, 2016, the first detection of gravitational waves was announced. The news had a great impact worldwide, as a revolutionary era for our understanding of Nature is now about to begin. In fact, the ability to observe gravitational waves will open new eyes on the cosmos, allowing us to learn much more on, e.g., black hole, neutron stars, supernovae and the origin and the evolution of the Universe.

The discovery of gravitational waves is the result of the combined, decades-long effort of hundreds of physicists. One of them is Giulio Mazzolo, who is now Maths and Physics teacher at the Ecole d’Humanité. Giulio started working on gravitational-wave astronomy for his Master’s thesis in Physics at the University of Padua, Italy (2008). Subsequently, he worked on this topic for his PhD and as post-doctoral researcher at the Max Planck Institute for Gravitational Physics in Hanover, Germany (2009 – 2014). During his experience in Hanover, Giulio worked as a member of the LIGO Scientific Collaboration, i.e., the Scientific Collaboration which, together with the Virgo Collaboration, announced the discovery of gravitational waves. For his PhD project, Giulio conducted a search for gravitational waves emitted by colliding black holes. This the same kind of signals as the one whose discovery has been announced recently. To perform his investigation, Giulio contributed to the improvement of some of the analysis techniques which led to the detection of gravitational radiation. For this reason, Giulio was invited by the LIGO and Virgo Collaborations to join the author list of the scientific paper reporting the first observation of gravitational waves, one of the most exciting breakthroughs in the history of science.

Congratulations, Giulio!
