Book Description
The Enrico Fermi Schools, a cultural initiative promoted by the Italian Physical Society (SIF), were initiated in 1953 in a period that marked the beginnings of what is now called cosmic ray astrophysics. Indeed, the very first edition of the School focused on the contribution of cosmic ray physics to the laws of elementary particle physics. Almost seventy years later, another School has been focusing on the foundations of cosmic ray astrophysics, and this book contains the lectures presented as Course 208 of the prestigious International School of Physics Enrico Fermi, Foundations of Cosmic Ray Astrophysics, held in Varenna, Italy from 23 to 29 June 2022. Topics covered in the book range from particle acceleration to cosmic ray transport, and from radiation processes to feedback of cosmic rays in galaxy formation. In particular, a thorough description of the physics of cosmic ray transport in turbulent magnetic fields, and of the production of magnetic perturbations in the presence of cosmic ray gradients is provided, both these phenomena being essential in describing particle acceleration at shocks and the transport of cosmic rays within the galaxy. The transport of cosmic rays in different environments is also discussed. This area of research has received an extraordinary boost in recent times, thanks to the now unprecedented accuracy of observations, and to the possibility of testing new ideas and complex scenarios offered by recent developments in numerical simulation, and the book will be of interest to all those working in the field of high energy astrophysics.

Book Description
Data from spacecraft such as Pioneer, Vela and Voyager have revealed the interstellar medium to be a remarkable physical system, which has served as a laboratory for the study of turbulent, supersonic, ideal magnetohydrodynamic (MHD) flows. The results of these studies provided confirmation of many theoretical models of the interstellar medium.

Book Description
Chapter 1 briefly describes the main properties of space plasmas and primary CR. Chapter 2 considers the problem of CR propagation in space plasmas described by the kinetic equation and different types of diffusion approximations. Chapter 3 is devoted to CR non-linear effects in space plasmas caused by CR pressure and CR kinetic stream instabilities with the generation of Alfvèn turbulence. In Chapter 4 different processes of CR acceleration in space plasmas are considered. The book ends with a list providing more than 1,300 full references, a discussion on future developments and unsolved problems, as well as Object and Author indexes.

Book Description
Developed from the lectures of a leading expert in plasma wave research, Plasma Kinetic Theory provides the essential material for an introductory course on plasma physics as well as the basis for a more advanced course on kinetic theory. Exploring various wave phenomena in plasmas, it offers wide-ranging coverage of the field. After intr

Book Description
If charged particles move through the interplanetary or interstellar medium, they interact with a large-scale magnetic ?eld such as the magnetic ?eld of the Sun or the Galactic magnetic ?eld. As these background ?elds are usually nearly constant in time and space, they can be approximated by a homogeneous ?eld. If there are no additional ?elds, the particle trajectory is a perfect helix along which the par- cle moves at a constant speed. In reality, however, there are turbulent electric and magnetic?elds dueto the interstellaror solar wind plasma. These ?elds lead to sc- tering of the cosmic rays parallel and perpendicular to the background ?eld. These scattering effects, which usually are of diffusive nature, can be described by s- tial diffusion coef?cients or, alternatively, by mean free paths. The knowledge of these parameters is essential for describing cosmic ray propagation as well as d- fusive shock acceleration. The latter process is responsible for the high cosmic ray energies that have been observed. The layout of this book is as follows. In Chap. 1, the general physical scenario is presented. We discuss fundamental processes such as cosmic ray propagation and acceleration in different systems such as the solar system or the interst- lar space. These processes are a consequence of the interaction between charged cosmic particles and an astrophysical plasma (turbulence). The properties of such plasmas are therefore the subject of Chap. 2.

Book Description
Designed to teach plasma physics and astrophysics 'from the ground up', this textbook proceeds from the simplest examples through a careful derivation of results and encourages the reader to think for themselves.
