The Theory of Cosmic Ray Modulation (Paperback)

The Theory of Cosmic Ray Modulation concretely lays out the current understanding of cosmic ray particle interactions, offering a comprehensive introduction to the underlying theory, observational data, and practical applications that have implications for various fields, including high-energy astrophysics, space weather, and cosmogenic isotope studies. The book provides a solid theoretical foundation, explaining the physical processes involved in cosmic ray modulation. It delves into mathematical details with meticulous explanations and applies them to topics ranging from the implications of cosmic rays in space-based anti-matter research to their role in studying solar variability over timescales, and even in planetary habitability.

This book not only provides a solid foundation for research but also offers wider perspectives on the impact of cosmic rays in our understanding of the universe. With its strong underlying theory and up-to-date coverage, it is a must-read for anyone actively working in the field of cosmic rays or on fields influenced by charged particle physics.

• Provides an essential starting point in the field of cosmic ray transport, including detailed explanations of underlying physical processes
• Includes observational data and current understandings on specific topics such as cosmic ray diffusion, drift, and turbulence.
• Covers mathematical expressions, derivations, and equations that describe the behavior of cosmic rays and their modulation processes
• Bridges the gap between plasma physics and space weather, making it an indispensable resource for space scientists seeking to understand the complexities of cosmic ray dynamics

Prof Du Toit Strauss completed his PhD in 2013 at the North-West University in South Africa, studying the transport of cosmic rays through the turbulent interplanetary medium using a combination of particle transport and large scale heliospheric MHD models. Since then he has focussed primarily on simulating the transport of solar energetic particles through the inner heliosphere, but has a general interest in the propagation of charged particles through turbulent plasmas (both from a theoretical and simulation perspective). On the experimental side he is leading the South African neutron monitor programme and has initiated a programme to characterize the radiation environment, at aviation altitudes, over Southern Africa. Prof Strauss completed research sabbaticals at the Ruhr University in Germany (funded through an Alexander von Humboldt fellowship) and the University of Alabama in Huntsville in the USA (as a Fulbright Visiting Scholar). He is currently appointed as professor of physics at the North-West University, and holds an affiliated status at the University of Alabama at Huntsville.

N. Eugene Engelbrecht is currently a professor in physics at the North-West University, South Africa, where he received his Ph.D. in physics, in which he studied the influence of turbulence on the transport of galactic cosmic rays by combining turbulence transport models with a numerical cosmic ray modulation code through first-principle modeling of these particle’s diffusion and drift coefficients. His research interests include modeling cosmic ray transport from first principles (both in the heliosphere and other astrospheres), turbulence and its transport (both theoretical and observational), and the diffusion of charged particles in turbulent plasmas.
