We are fascinated by space. The vast and dynamic sky makes us wonder and dream. We study it at all frequency ranges and via messengers other than photons, like cosmic-rays and gravitational waves, both from the ground and space. Excelling in our research, we are interested in developing theoretical models and technologies to scrutinize planets, stars, galaxies, and the whole universe. We also aim at using space technologies to understand more about Earth, to model better its climate change, and to develop predictive tools that could help avoid the effects of natural disasters. Overall, the main asset of our institute is the ability to produce cutting-edge theoretical modelling of what we study observationally, with instruments we help build.
