Measuring the Universe A Multiwavelength Perspective [Paperback]

A one-stop guide to astronomical instrumentation and data acquisition, with a focus on the underlying principles behind each instrument's operation.Covering the full range of modern instrumentation from radio to gamma ray, this is a comprehensive guide to state-of-the-art astronomical measurements and data acquisition. With an emphasis on underlying principles, detailed explanations allow readers to apply their knowledge to new developments and to understand how instruments of all types operate.Covering the full range of modern instrumentation from radio to gamma ray, this is a comprehensive guide to state-of-the-art astronomical measurements and data acquisition. With an emphasis on underlying principles, detailed explanations allow readers to apply their knowledge to new developments and to understand how instruments of all types operate.Astronomy is an observational science, renewed and even revolutionized by new developments in instrumentation. With the resulting growth of multiwavelength investigation as an engine of discovery, it is increasingly important for astronomers to understand the underlying physical principles and operational characteristics for a broad range of instruments. This comprehensive text is ideal for graduate students, active researchers and instrument developers. It is a thorough review of how astronomers obtain their data, covering current approaches to astronomical measurements from radio to gamma rays. The focus is on current technology rather than the history of the field, allowing each topic to be discussed in depth. Areas covered include telescopes, detectors, photometry, spectroscopy, adaptive optics and high- contrast imaging, millimeter-wave and radio receivers, radio and optical/infrared interferometry, and X-ray and gamma-ray astronomy, all at a level that bridges the gap between the basic principles of optics and the subject's abundant specialist literature.
