Essential Relativistic Astrophysics

This book offers a concise and practical introduction to relativistic astrophysics, designed for advanced undergraduate and graduate students, as well as researchers seeking a rapid refresher or a fresh perspective. Covering the essential concepts of special and general relativity, the book emphasizes their application to modern high-energy astrophysics. Through numerous worked examples, it connects fundamental theory to the physics of compact objects, relativistic jets, and high-energy radiation processes, while also introducing the tools used to analyze X- and gamma-ray data. A distinctive feature of the book is its integrated approach, linking relativistic physics with observational techniques and instrumentation, including a discussion of contemporary data analysis methods. The extensive references provides a gateway for readers who wish to explore advanced topics in greater depth.
