LISA and the Future of Gravitational Wave Physics and Astronomy
Gravitational waves offer views of the universe which complement those in electromagnetic waves and neutrinos. Just as different frequencies of the electromagnetic spectrum highlight different astrophysical phenomena, different frequencies of gravitational radiation will highlight different kinds of objects. The NASA/ESA Laser Interferometer Space Antenna (LISA), planned for launch in 2010, will detect and measure gravitational radiation from astronomical sources at frequencies 0.0001 Hz to 0.1 Hz (vs. 10-1000 Hz for ground-based detectors like LIGO). LISA will detect continuous signals from: thousands of exotic binary stars in the Milky Way, merging supermassive black holes in the nuclei of merging galaxies at redshifts from 0 to 100, and compact stars scattered into supermassive black holes. The latter will provide precision tests of strong-field predictions of relativity, such as the No-Hair Theorem and energy extraction from rotating black holes. We will conclude with an outline of some of the limitations of, and remarkable possibilities for the future of gravitational wave physics and astronomy.

Overview Of Gravitational Waves, An: Theory, Sources And Detection
This book describes detection techniques used to search for and analyze gravitational waves (GW). It covers the whole domain of GW science, starting from the theory and ending with the experimental techniques (both present and future) used to detect them.The theoretical sections of the book address the theory of general relativity and of GW, followed by the theory of GW detection. The various sources of GW are described as well as the methods used to analyse them and to extract their physical parameters. It includes an analysis of the consequences of GW observations in terms of astrophysics as well as a description of the different detectors that exist and that are planned for the future.With the recent announcement of GW detection and the first results from LISA Pathfinder, this book will allow non-specialists to understand the present status of the field and the future of gravitational wave science.
