The two-volume book Gravitational Waves provides a comprehensive and detailed account of the physics of gravitational waves. While Volume 1 is devoted to the theory and experiments, Volume 2 discusses what can be learned from gravitational waves in astrophysics and in cosmology, by systematizing a large body of theoretical developments that have taken place over the last decades. The second volume also includes a detailed discussion of the first direct detections of gravitational waves. In the author's typical style, the theoretical results are generally derived afresh, clarifying or streamlining the existing derivations whenever possible, and providing a coherent and consistent picture of the field. The first volume of Gravitational Waves , which appeared in 2007, has established itself as the standard reference in the field. The scientific community has eagerly awaited this second volume. The recent direct detection of gravitational waves makes the topics in this book particularly timely.

"The book covers a staggering breadth of material and is extremely useful as a bird's-eye overview of the field... From now on I will recommend it as the best entry point for students who want to join this blooming research field" - Emanuele Berti, Physics Today

"Michele Maggiore's textbook spends equal effort reviewing the astrophysical and cosmological theories behind the production of cosmic gravitational waves and discussing the observational constraints that could be gleaned from the handful of LIGO/Virgo detections, the pulsar timing arrays and upcoming facilities like LISA." - Nature Astronomy
