Book Description
Astrometry has historically been fundamental to all the fields of astronomy, driving many revolutionary scientific results. ESA's Gaia mission is astrometrically, photometrically and spectroscopically surveying the full sky, measuring around a billion stars to magnitude 20, to allow stellar distance and age estimations with unprecedented accuracy. With the complement of radial velocities, it will provide the full kinematic information of these targets, while the photometric and spectroscopic data will be used to classify objects and astrophysically characterize stars. IAU Symposium 330 reviews the first 2.5 years of Gaia activities and discusses the scientific results derived from the first Gaia data release (GDR1). This significant increase in the precision of the astrometric measurements has sharpened our view of the Milky Way and the physical processes involved in stellar and galactic evolution. To many, the Gaia revolution heralds a transformation comparable to the impact of the telescope's invention four centuries ago.

Book Description
With information and scale as central themes, this comprehensive survey explains how to handle real problems in astronomical data analysis using a modern arsenal of powerful techniques. It treats those innovative methods of image, signal, and data processing that are proving to be both effective and widely relevant. The authors are leaders in this rapidly developing field and draw upon decades of experience. They have been playing leading roles in international projects such as the Virtual Observatory and the Grid. The book addresses not only students and professional astronomers and astrophysicists, but also serious amateur astronomers and specialists in earth observation, medical imaging, and data mining. The coverage includes chapters or appendices on: detection and filtering; image compression; multichannel, multiscale, and catalog data analytical methods; wavelets transforms, Picard iteration, and software tools. This second edition of Starck and Murtagh's highly appreciated reference again deals with topics that are at or beyond the state of the art. It presents material which is more algorithmically oriented than most alternatives and broaches new areas like ridgelet and curvelet transforms. Throughout the book various additions and updates have been made.

Book Description
Gaia is an ambitious satellite mission to chart a three-dimensional map of the Milky Way. By measuring the proper motions and parallaxes for a billion stars, Gaia is set to transform the way we study the composition, formation and evolution of our galaxy. Concurrently the LAMOST survey facility in China will make a complementary spectral survey of millions of objects in much of the northern sky. This volume, comprising the reviews and contributed talks presented at IAU Symposium 298, is an up-to-date review of what we know about the Milky Way as a galaxy prior to the launch of Gaia. It covers many topics including the status of dynamical simulations, photometric and spectroscopic surveys, and interstellar matter in the Milky Way, as well as detailed studies of stellar atmospheres. The expert reviews will interest all those working on Milky Way astronomy as well as galaxy formation and evolution.

Book Description
An excellent new analysis of federalism and the EU that investigates their mutual impact. It shows how scholars of comparative politics increasingly include the EU among their cases when investigating the impact of federalism on key issues such as policy making. The last decade saw a new wave of scholarly publications hit the shores as research on federalism and on the EU came together. These emerging strands of research genuinely enrich our understanding of the EU and its politics. Despite this recent wave, the topic of federalism and the EU is still extremely fruitful. This volume contributes to the continuing debate at a moment in time when the EU is undergoing profound changes. It is structured around four interrelated dimensions: the constitutional/theoretical dimension the institutional vision the party/citizens dimension the policy dimension. This structure allows the reader to consecutively "funnel down" from the more theoretical and abstract levels to the more concrete policy oriented level.

Book Description
In Southern Gems, Stephen James O'Meara makes a detour beneath the southern skies, presenting a fresh list of 120 deep-sky objects for southern hemisphere stargazers to observe. Showcasing many exceptional objects catalogued by the pioneering observer James Dunlop, known as the 'Messier of the southern skies', all are visible through small- to moderate-sized telescopes or binoculars under dark skies. The list features some of the blackest dark nebulae, icy blue planetary nebulae and magnificent galaxies of all types. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical background information. Whether you live in the southern hemisphere or are just visiting, this new Deep-Sky Companion will make a perfect observing partner, whatever your background. There is no other southern sky guide like it on the market.

Book Description
The large-scale structure of the Universe is dominated by vast voids with galaxies clustered in knots, sheets, and filaments, forming a great 'cosmic web'. In this personal account of the major astronomical developments leading to this discovery, we learn from Laird A. Thompson, a key protagonist, how the first 3D maps of galaxies were created. Using non-mathematical language, he introduces the standard model of cosmology before explaining how and why ideas about cosmic voids evolved, referencing the original maps, reproduced here. His account tells of the competing teams of observers, racing to publish their results, the theorists trying to build or update their models to explain them, and the subsequent large-scale survey efforts that continue to the present day. This is a well-documented account of the birth of a major pillar of modern cosmology, and a useful case study of the trials surrounding how this scientific discovery became accepted.

Book Description
This authoritative book presents the theoretical development of gravitational physics as it applies to the dynamics of celestial bodies and the analysis of precise astronomical observations. In so doing, it fills the need for a textbook that teaches modern dynamical astronomy with a strong emphasis on the relativistic aspects of the subject produced by the curved geometry of four-dimensional spacetime. The first three chapters review the fundamental principles of celestial mechanics and of special and general relativity. This background material forms the basis for understanding relativistic reference frames, the celestial mechanics of N-body systems, and high-precision astrometry, navigation, and geodesy, which are then treated in the following five chapters. The final chapter provides an overview of the new field of applied relativity, based on recent recommendations from the International Astronomical Union. The book is suitable for teaching advanced undergraduate honors programs and graduate courses, while equally serving as a reference for professional research scientists working in relativity and dynamical astronomy. The authors bring their extensive theoretical and practical experience to the subject. Sergei Kopeikin is a professor at the University of Missouri, while Michael Efroimsky and George Kaplan work at the United States Naval Observatory, one of the world?s premier institutions for expertise in astrometry, celestial mechanics, and timekeeping.
