This 1963 monograph is a foundational pillar of modern high-energy astrophysics. Written by Nobel laureate Vitaly Ginzburg and the eminent theorist Sergei Syrovatskii, it represents the first systematic attempt to synthesize the physics of cosmic rays with the burgeoning field of radio astronomy. Published by the Academy of Sciences of the USSR, the book arrived at a transformative moment when the "synchrotron hypothesis" for cosmic radio emission was moving from a bold theory to an established scientific fact.
The work is historically significant for being the first to comprehensively apply the theory of magnetobremsstrahlung (synchrotron) radiation to explain the non-thermal radio emission observed from our Galaxy and distant extragalactic sources. Ginzburg and Syrovatskii meticulously demonstrate that the cosmic rays detected on Earth and the radio waves reaching our telescopes are two sides of the same coin—relativistic electrons moving through cosmic magnetic fields.
The authors provide a rigorous analysis of the chemical composition of cosmic rays, their energy spectrum, and their motion through the interstellar medium. They delve into the possible sources of these particles, debating the roles of supernovae, solar flares, and active galactic nuclei. A central theme is the diffusion model of cosmic ray propagation, which remains a cornerstone of the field today. The text is enriched with technical data, complex derivations of radiation intensity, and maps of the radio sky that were cutting-edge for the early 1960s.
This 1963 hardcover edition is a collector's item of immense scientific value. It captures the intellectual rigor of the Soviet school of astrophysics at its peak and stands as the definitive record of how humanity first began to understand the high-energy processes that shape the Universe. For the historian of science or the professional astrophysicist, this volume is not merely a book, but the primary source code for the "Ginzburg-Syrovatskii" era of cosmic ray research.
