The Group
The Group
The high-energy astrophysics group in Arcetri was founded by Franco Pacini and is one of the leading italian reserch group in the field of non-thermal particle acceleration, cosmic rays, relativistic fluid dynamics, and supernova remnants. The group is mostly involved in theroretical modelling of astrophysical objects and processes, with a focus on numerical simulations. The various are involved in different projects at the national and international level, ranging from theoretical investigation of key astrophysical processes to the developement of the science for the next generation gamma and X-ray telescopes. The group has a long standing collaboration with the Università degli Studi di Firenze and the local plasma physics group.
