Giovanni is research active within the area of astrophysics and is a member of the Extragalactic Astrophysics Research Group. The main goal of his research is the understanding of how the light emitted from stars and other radiation sources propagates within galaxies, where it is both scattered and absorbed by interstellar dust particles. The accurate modelling of this phenomena is a necessary step for the correct interpretation of multi-wavelength maps of galaxies and still one of the big challenges in modern astronomy.

Full Profile

Giovanni´s research focuses on the study of interstellar dust heating and emission within galaxies. This research is fundamental to understand the intrinsic distribution of stars and dust in both the Milky Way and external galaxies. This is because the light emitted by stars in a galaxy is both absorbed and scattered by interstellar dust particles. This process has the effect to dim the optical/UV light propagating within galaxies and, at the same time, power the dust emission observed in the infrared wavelength regime. Giovanni's main project consists in the development of a 3D ray-tracing radiation transfer code, called DART-Ray, which is designed to model the propagation of light within the interstellar medium of galaxies with arbitrary geometries. This code can be used to predict the appearance of numerical simulations of galaxies as well as modelling the UV to sub-mm emission from real galaxies.
