Book Description
Galactic and Extragalactic Radio Astronomy is a fundamental text for graduate students and professional astronomers and covers all aspects of radio astronomy beyond the solar system. Each chapter is written by a renowned expert in the field and contains a review of a particular area of radio astronomy and presents the latest observations and interpretations as well as an extensive view of the literature (as of 1988). Topics covered include: galactic continuum emission, HII regions, the diffuse interstellar medium, interstellar molecules, astronomical masers, neutral hydrogen, the galactic center, radio stars, supernova remnants, pulsars, extragalactic hydrogen, radio galaxies and quasars, the microwave background, and cosmological radio sources.

Book Description
This book introduces the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), also known as the "The Sky Eye", one of the China’s big science facilities. Using easy-to-understand language, the book covers the scientific background, construction process, achievements, and effects of FAST on the development of the national economy. With a large number of intuitive and vivid images and videos, the book presents basic information on FAST for general readers who are interested in astronomy.

Book Description
: The Square Kilometre Array (SKA) will provide more than one order of magnitude improvement in sensitivity compared with any existing radio telescope over a wavelength range of several hundred to one, from decametric to microwave wavelengths. It will revolutionize the study of the most abundant element in the Universe, hydrogen, from the epoch of reionisation to the present-day, probing the onset formation period of the very first stars, will closely scan proto-planets and, through the precision timing of pulsars, will detect the distortions of space-time due to gravitational radiation. The SKA is a sensing network spanning 3000 km from its centre and with a collecting area of more than 1 square kilometre, using technologies of the 21st century. The SKA will make the study of a wide range of phenomena initially studied at other wavelengths possible at radio wavelengths, as well as opening a new discovery window on new phenomena at radio wavelengths. Symposium 7 of the JENAM 2010 aimed at bringing these diverse opportunities to the attention of both theoretical and observational astronomers working at all wavelengths, including the potential for synergies with other facilities. The meeting highlighted the scientific potential of the SKA, discussed scientific priorities and their impact on the design of the SKA, explored the synergies between the SKA and other next-generation astronomical facilities in different wavelength domains such as the ALMA, ELTs, LSST, JWST, GRE, IXO, Gaia and Euclid, and high-energy facilities (Auger), explored the “cyber–infrastructure” that may become available for the distribution and distributed analysis of SKA data.
Views of the U.S. NAS and NAE on Agenda Items at the World Radiocommunication Conference 2015

Pages : 51
Book Description
The World Radiocommunication Conference (WRC) is a meeting of official delegations from over 140 nations and is organized by the International Telecommunication Union (ITU). Delegates meet every few years to negotiate proposals to changes in international radio spectrum regulations; changes that would be enforced by the ITU internationally if approved. Proposals are brought up during a WRC and then negotiated at the next WRC. The time in between each WRC allows for national governments to work internally and with their regional counterparts to develop a consensus position on each proposal. The consensus position can then be presented at the next WRC. Each proposal is referred to as an agenda item and agenda items are specific and propose narrow yet potentially substantial changes to the use of the spectrum that can have significant impact on its users. Most agenda items support the active use of the spectrum, so it is important for vulnerable, passive services to voice their concerns about potentially adverse effects on their operations. Two U.S. passive services, the passive Radio Astronomy Service (RAS) and the Earth Exploration-Satellite Service (EESS), provide scientific observations of the universe and Earth through the use of advanced receiver technology with extreme sensitivity and the employment of complex noise reduction algorithms. Even with such technology, RAS and EESS are seriously adversely affected by what most active services would consider extremely low noise levels. Views of the U.S. NAS and NAE on Agenda Items at Issue at the World Radiocommunication Conference 2015 present the NAS and NAE\'s views on agenda items that affect RAS and EESS. This report includes a list of each agenda item, how it affects the programs, and the committee\'s recommendations.
The Unsolved Universe: Challenges for the Future
Author: Mario MonteiroPublisher: Springer Science & Business Media
ISBN: 9401702357
Category : Science
Languages : en
Pages : 152
Book Description
The reviews and highlights included in this book of proceedings of the plenary sessions, of the Joint European and National Astronomical Meeting (2002), cover some of the major fields and projects which will determine the research in astronomy in the next decades. The highlights have been presented by young astronomers from several European countries, selected from a list of proposals submitted by different institutions across Europe. This book reflects the multi-disciplinarity and interaction that took place in the meeting. By including reviews on space and ground-based observational programmes, the scientific topics are associated with the new observational efforts in instrumentation. These projects, under development, are expected to drive the research in the coming decades. With such a wide and interdisciplinary coverage this book provides a comprehensive review on the present status and expectations for some of the major fields in astrophysics. This work is of great relevance for students and researchers alike, as it provides an introductory approach to a wide range of fields in Astronomy, but also includes some detailed reviews for the major topics in each field.
