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.

Describing interstellar matter in our galaxy in all of its various forms, this book also considers the physical and chemical processes that are occurring within this matter. The first seven chapters present the various components making up the interstellar matter and detail the ways that we are able to study them. The following seven chapters are devoted to the physical, chemical and dynamical processes that control the behaviour of interstellar matter. These include the instabilities and cloud collapse processes that lead to the formation of stars. The last chapter summarizes the transformations that can occur between the different phases of the interstellar medium. Emphasizing methods over results, The Interstellar Medium is written for graduate students, for young astronomers, and also for any researchers who have developed an interest in the interstell

Reflector antennas are widely used in the microwave and millimeter wavelength domain. Radio astronomers have developed techniques of calibration of large antennas with radio astronomical methods. These have not been comprehensively described. This text aims to fill this gap. The Paraboloidal Reflector Antenna in Radio Astronomy and Communication: Theory and Practice takes a practical approach to the characterization of antennas. All calculations and results in the form of tables and figures have been made with Mathematica by Wolfram Research. The reader can use the procedures for the implementation of his/her own input data. The book should be of use to all who are involved in the design and calibration of large antennas, like ground station managers and engineers, practicing radio astronomers, and finally, graduate students in radio astronomy and communication technology.

There are several textbooks available on solar astronomy which deal with advanced astrophysical aspects of solar physics, and books which provide very elementary knowledge about the Sun. This book will help to bridge the gap. It aims to stimulate interest in solar astronomy, presenting at one place the basic methods and techniques used in the field, together with the latest findings and the excitement in solar physics. As solar astronomy is becoming very popular among amateur astronomers and laymen, the book provides the practical knowledge to build simple solar telescopes and other equipment for making solar observations. Amateur astronomers have made important contributions to solar astronomy, and this book will help to guide them in their endeavours. The book can also serve as a text for undergraduate and graduate students starting out on solar physics. Using it, graduate students can easily embark on specific topics of research in solar astronomy.

The common perception of Celestial Mechanics is that of a discipline which needs advanced mathematics and astronomy to be understood. Yet modern Celestial Mechanics has a rather different taste and a truly interdisciplinary nature. The number of celestial objects known to mankind has dramatically increased, the long-awaited presence of extrasolar planets has been eventually detected around other stars, spaceflight dynamics has brought new applications encompassing rocked dynamics, the place-in-orbit of artificial satellites and interplanetary mission design. Solar System exploration has grown as a long term strategy for the construction of a permanent base on the Moon and a manned mission to Mars.
The aim of the book is to show to the people at large, as well as to a more skilled audience, the many fascinating aspects of modern celestial mechanics. After giving to the reader the necessary technical tools needed for a basic understanding of the underlying physical phenomena (using only elementary mathematics), facts and figures are provided on historical events, modern discoveries and future applications. Contents are divided into major topics where the three "souls" of modern celestial mechanics (dynamical systems, Solar System & stellar systems, spaceflight dynamics) play a major role. As an example, spin-orbit resonances can be explained using fractional algebra and subsequently described in action as "cosmic spinning tops". Easily observable effects such as the existence of a "dark side of the Moon" (and of many other satellites) can be compared to the "complete synchronous rotation" achieved by a geostationary telecommunication satellite in order to be always in view of the receiving parabolas on the ground. On longer time scales, the consequences of spin-orbit interaction may dramatically change the evolution of a planet when chaos enters the scene and must be taken into account in searching habitable planets around other stars.

Fundamental Astronomy gives a well-balanced and comprehensive introduction to the topics of classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. The fifth edition of this successful undergraduate textbook has been extensively modernized and extended in the parts dealing with the Milky Way, extragalactic astronomy and cosmology as well as with extrasolar planets and the solar system (as a consequence of recent results from satellite missions and the new definition by the International Astronomical Union of planets, dwarf planets and small solar-system bodies). Furthermore a new chapter on astrobiology has been added. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference and entrée for dedicated amateur astronomers.

Of all the fixed stars in the night sky, Sirius is by far the brightest – almost twice as bright as its nearest rival, the star Canopus, which lies too far south to be viewed from most of the Northern Hemisphere. Only the Sun, Moon and the planets Venus, Jupiter and, at times, Mars, appear brighter. Sirius, with its flashing brilliance, is a striking feature of the northern winter sky and has understandably drawn the attention of observers of the night sky for thousands of years.
Sirius has many names. Astronomers recognize over fifty designations for the star, but the most commonly used is Alpha Canis Majoris, the brightest star in the constellation Canis Major. This is Latin for the 'Great Dog', which has led to its popular nickname the ‘Dog Star’. Over the centuries many beliefs have come to be associated with Sirius. Some of these beliefs still echo in such phrases as ‘the dog days of summer’, which the ancient Romans understood well. Other old beliefs long ago fell from public consciousness — only to be revived and to grow into modern popular and scientific controversies. Although these beliefs may seem quite recent, many have their origins in the ancient lore surrounding Sirius; humans seem naturally drawn to its brilliance, and a surprising number of modern cults have nucleated around beliefs in which Sirius plays a prominent role.

Since the very beginning of astronomy, people have looked up sky and constructed patterns the constellations out of the almost random scattering of stars in the night sky. The fact that the constellations are still used to day reflects not their historical origins, but their usefulness in identifying bright stars in the rotating dome of the sky. Most people (and all astronomers) are familiar with, for example, the constellation of Orion and can thus easily point to Betelguese and Bellatrix as being Orions "shoulders". It is the pattern made by the constellation that makes them easy to identify. What applies to big groups of stars can also be applied to smaller ones, and this book provides a set of memorable mini-constellations to help in identifying and remembering stars in the binocular or low magnification telescopic field. Suitable for observers using binoculars and medium size telescopes, this catalog includes star pictures, dot-to-dot outlines of the objects ( on a negative photograph for clarity ), and an artistic image next to the star patterns. Size, stellar magnitudes, and coordinates are provided, along with north direction, star-hopping instructions & Sky Atlas 2000 references. There are sixty-seven "pattern asterisms" in this catalog. Most are easy to see in sixty millimetre binoculars, and few are what observers describe as "challenging". The imaginative observer will surely begin to develop a new insight into star patterns, and will start seeing patterns of his own, under this catalog's influence!
