The acclaimed graduate text on astrophysical radiation, completely revised

The interaction of electromagnetic radiation with matter underpins nearly every observable astrophysical phenomenon, yet the subject demands fluency across classical electrodynamics, quantum mechanics, and statistical mechanics. Now in its Second Edition, Radiative Processes in Astrophysics provides a rigorous, unified treatment of these topics. Authored by researchers from the Harvard-Smithsonian Center for Astrophysics and the University of Florida, this revision builds on decades of classroom use.

This edition adds around 100 problems with solutions, sidebars connecting theory to contemporary discoveries in astrophysics, chapter introductions that contextualize each topic, and appendices reviewing quantum mechanics and statistical mechanics fundamentals. New application boxes relate core material to phenomena such as black hole accretion disks and modified blackbody spectra, strengthening the connection between formalism and observation.

Readers will also find:

• A structured progression from Maxwell's equations through bremsstrahlung, synchrotron radiation, Compton scattering, and radiative transfer theory
• Sidebars and application boxes linking classical derivations to recent observational discoveries across modern astrophysics
• Appendices providing self-contained reviews of quantum mechanics and statistical mechanics for readers needing targeted refreshers
• Around 100 worked problems with solutions designed to reinforce analytical skills and deepen physical intuition
• Chapter introductions that frame each topic within the broader context of contemporary astrophysical research

Designed for master's and doctoral students in physics and astrophysics, as well as lecturers seeking a proven course text, Radiative Processes in Astrophysics delivers the depth and rigor required to build lasting competence in electromagnetic radiation theory and its astrophysical applications.
