Despite the not-always adequate coverage provided by the Italian media, the European Rosetta Mission, which carried out in the last days the first landing on a comet in history, kept the whole world holding its breath and has been an extraordinary scientific, technological and organizational success. When initially proposed by ESA – the European Space Agency – the aim of the mission was practically science fiction. But thanks to the cooperation of thousands of scientists from tens of research bodies and to an effective partnership networks with state-of-the-art aerospa
I am an astrophysicist, and my research focuses on the formation and evolution of galaxies. In particular, I develop analytical and numerical models that allow us to study the physical processes that drive galaxy formation and evolution as a function of cosmic time, in a cosmological context.
Gamma-ray bursts (GRBs) are the most powerful explosions so far observed in the universe since the big bang. They are a frequent phenomenon (approximately an explosion per day) and can be observed in all sky directions (isotropic). Gamma-ray bursts can not be seen from Earth because gamma and X rays are absorbed by the atmosphere.
