Available in PDF, EPUB and Kindle. Book excerpt: This volume is the proceedings of IAU Symposium No. 118 on "Instrumentation. and Research Programmes for Small Telescopes", where small telescopes were defined as those ground-based instruments with apertures less than 1.5m. The scientific goal of the symposium was to emphasise research programmes which were more suited to smaller tele scopes, on which frequent regular observations can be made. A wide variety of topics on instrumentation, photometry, spectroscopy and polarimetry of objects in the solar system to extragalactic systems were discussed. Each of the four scientific days of the symposium comprised a number of invited review papers, contributed oral papers and discussion sessions devoted purely to the large number (~4) of poster papers. An introductory paper on the research potential of small telescopes sets the scene for the symposium. The proceedings have then been divided into three sections. Section I: Telescopes and instrumentation; Section II: Photometric research programmes; Section III: Spectroscopic research programmes. The diversity of topics within each of these sections indicated the extent to which small telescopes have (and can) contribute greatly to astronomical research. Dr J.A. Graham's summary of the symposium, which illustrates the opportunities available with small telescopes, concludes these proceedings. As in all symposia, the importance of the discussion following each paper was realised. The discussion was recorded on tape (and wherever possible on questions and answer sheets), transcribed and then edited.

Available in PDF, EPUB and Kindle. Book excerpt: "The polarization study of celestial objects is a valuable part of optical astronomy, and the author has done exceptionally well in bringing to gether contributions treating all aspects of the polarimetry field. . . . The first section contains a fine introduction and an excellent and definitive history of the subject. . . . The volume is well illustrated. . . . Highly recommended."ÑChoice "The high quality of this book is clearly due to strict editorial attention to each paper and the discussions. Gehrel's book will surely stand for many years as the fundamental reference source for polarization studies in astronomy as well as in atmospheric physics."ÑJournal of the Assoc. of Lunar and Planetary Observers
Download or read book Measuring the Universe written by George H. Rieke and published by Cambridge University Press. This book was released on 2017-05-25 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. Color versions of figures and solutions to selected problems are available online at www.cambridge.org/9780521762298.

This book was released on 2013-11-21 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr J. Landi Dessy, Director of the Astronomical Observatory, Cordoba, Argentina, invited the International Astronomical Union to hold a Symposium in Cordoba in connection with the celebration of the Centennial of the Cordoba Observatory; the date of foundation is October 24, 1871. He proposed that the Symposium should deal with Spectral Classification and Multicolour Photometry as seven years had elapsed since the Symposium No. 24 in Saltsj6baden, and much development had occurred in the field. The invitation and the proposal were accepted by the IAU, and the Symposium was held in Villa Carlos Paz, near Cordoba, between October 18 and October 24, 1971. It was attended by about 50 scientists representing Argentina, Canada, Chile, Den mark, France, Germany, Italy, Mexico, Sweden, Switzerland, U.K., U.S.A., Vatican City State and Venezuela. The Symposium was divided into four sessions: 1. Classification of slit spectra, 2. Classification of objective-prism spectra, 3. Photometric classification, 4. Catalogues and documentation. It was decided not to include problems of calibration of absolute magnitudes and temperatures of stars but to refer this to a separate symposium. The contents of the present volume follow closely the programmes of the individual sessions of the Symposium. All the participants at the Symposium appreciated the excellent hospitality of their Argentinian hosts and the efficient help given by the staff ofthe Cordoba Observatory.

Available in PDF, EPUB and Kindle. Book excerpt: The Spitzer Space Observatory, originally known as the Space Infrared Telescope Facility (SIRTF), is the last of the four “Great Observatories”, which also include the Hubble Space Telescope, the Chandra X-ray Observatory, and the Compton Gamma Ray Observatory. Developed over twenty years and dubbed the “Infrared Hubble", Spitzer was launched in the summer of 2003 and has since contributed significantly to our understanding of the universe. George Rieke played a key role in Spitzer and now relates the story of how that observatory was built and launched into space. Telling the story of this single mission within the context of NASA space science over two turbulent decades, he describes how, after a tortuous political trail to approval, Spitzer was started at the peak of NASA’s experiment with streamlining and downsizing its mission development process, termed “faster better cheaper.” Up to its official start and even afterward, Spitzer was significant not merely in terms of its scientific value but because it stood at the center of major changes in space science policy and politics. Through interviews with many of the project participants, Rieke reconstructs the political and managerial process by which space missions are conceived, approved, and developed. He reveals that by the time Spitzer had been completed, a number of mission failures had undermined faith in “faster-better-cheaper” and a more conservative approach was imposed. Rieke examines in detail the premises behind “faster better cheaper,” their strengths and weaknesses, and their ultimate impact within the context of NASA’s continuing search for the best way to build future missions. Rieke’s participant’s perspective takes readers inside Congress and NASA to trace the progress of missions prior to the excitement of the launch, revealing the enormously complex and often disheartening political process that needs to be negotiated. He also shares some of the new observations and discoveries made by Spitzer in just its first year of operation. As the only book devoted to the Spitzer mission, The Last of the Great Observatories is a story at the nexus of politics and science, shedding new light on both spheres as it contemplates the future of mankind’s exploration of the universe.

Download or read book Detection of Light written by G. H. Rieke and published by Cambridge University Press. This book was released on 1996-06-27 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does a quantum well detector, a silicon BIB or a CCD work? How are heterodyne techniques used in infrared detectors and submillimeter receivers? And how do you specify the performance of any detector system? This volume answers all these questions with an up-to-date review of all the techniques for the detection of radiation. This presentation approaches detectors from the perspective of the underlying physics; and in this way it provides a unified understanding of the detection of radiation in the ultraviolet through to the submillimetre. Clearly worked examples demonstrate the physics involved and problems are provided to increase the reader's knowledge of how each system works. This clearly written and authoritative review of modern detector systems will develop the understanding of final year undergraduate and graduate students, and will provide a valuable reference for professionals in astronomy, engineering and physics.
