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 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.

Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation of the literature concerning all aspects of astronomy, astrophysics, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 39 records literature published in 1985 and received before August 15, 1985. Some older documents which we received late and which are not surveyed in earlier volumes are included too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. On account of the introduction of an object index the scope of index information will be considerably enlarged beginning with this volume. In connection with the subject index an additional source to satisfy the needs of retrieval is opened up. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Mona El-Choura, Ms. Monika Kohl, Ms. Sylvia Matyssek. Ms. Karin Burkhardt, Ms. Susanne Schlotelburg, and Mr. Stefan Wagner supported our task by careful proofreading. It is a pleasure to thank them all for their encouragement.

Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union.

We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. Dr. Siegfried Böhme retired from his duties as co-editor of Astronomy and Astro physics Abstracts on December 31, 1987. Since 1950 he partieipated in the biblio graphie work of the institute. He served as a reviewer for the Astronomischer Jahresbericht and became one of the editors of Astronomy and Astrophysics Ab stracts in 1969. After his retirement in 1975 he took care of, particularly, the Russian literature on a voluntary basis for 12 years. It is a pleasure to thank Siegfried Böhme for his valuable contributions. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers.

From the reviews: Astronomy and Astrophysics Abstracts has appeared in semi-annual volumes since 1969 and it has already become one of the fundamental publications in the fields of astronomy, astrophysics and neighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. ... The abstracts are classified under more than hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world." Space Science Reviews #1 "Dividing the whole field plus related subjects into 108 categories, each work is numbered and most are accompanied by brief abstracts. Fairly comprehensive cross-referencing links relevant papers to more than one category, and exhaustive author and subject indices are to be found at the back, making the catalogues easy to use. The series appears to be so complete in its coverage and always less than a year out of date that I shall certainly have to make a little more space on those shelves for future volumes."

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.
