Fundamentals of Astrophysics

Attilio Ferrari was Professor Emeritus of Astronomy and Astrophysics at the Faculty of Sciences of the University of Torino, Italy until his passing in 2022.Professor Ferrari served as Director of the Astronomical Observatory of Torino from 1986 to 2001. During this period, he was a member of the board of directors of the National Consortium of Astronomy and Astrophysics CNAA (1996–2001) and the Istituto Nazionale di Astrofisica – INAF (2000–3). Throughout his career, he contributed to numerous scientific boards. He served as President of the Inter-University Consortium for Space Sciences and also President of the Torino Museum of Astronomy and Space Science. In 2012, he was recognized with the Bruno Rossi Prize (High Energy Astrophysics Division, American Astronomical Society) as a member of the AGILE Team.Professor Ferrari's research interests encompassed a broad spectrum, including theoretical models of the energetics and morphology of extragalactic radio sources and active galactic nuclei, numerical simulations of nonlinear hydrodynamical and magneto-hydrodynamical supersonic flows from active stars and galaxies and accretion disks, and high-energy plasmas in astrophysics and in fusion machines. He authored over 250 scientific papers in international journals and two textbooks.
