Multiwavelength Mapping of Galaxy Formation and Evolution ; Proceedings of the ESO Workshop Held at Venice, Italy, 13-16 October 2003
The possibilities of astronomical observation have dramatically increased over the last decade. Major satellites, like the Hubble Space Telescope, Chandra and XMM Newton, are complemented by numerous large ground-based observatories, from 8m-10m optical telescopes to sub-mm and radio facilities. As a result, observational astronomy has access to virtually the whole electromagnetic spectrum of galaxies, even at high redshifts. Theoretical models of galaxy formation and cosmological evolution now face a serious challenge to match the plethora of observational data. In October 2003, over 170 astronomers from 15 countries met for a 4-day workshop to extensively illustrate and discuss all major observational projects and ongoing theoretical efforts to model galaxy formation and evolution. This volume contains the complete proceedings of this meeting and is therefore a unique and timely overview of the current state of research in this rapidly evolving field.
In Search of Dark Matter
The dark matter problem is one of the most fundamental and profoundly difficult to solve problems in the history of science. Not knowing what makes up most of the known universe goes to the heart of our understanding of the Universe and our place in it. In Search of Dark Matter is the story of the emergence of the dark matter problem, from the initial erroneous ‘discovery’ of dark matter by Jan Oort to contemporary explanations for the nature of dark matter and its role in the origin and evolution of the Universe. Written for the educated non-scientist and scientist alike, it spans a variety of scientific disciplines, from observational astronomy to particle physics. Concepts that the reader will encounter along the way are at the cutting edge of scientific research. However the themes are explained in such a way that no prior understanding of science beyond a high school education is necessary.
Human vision and the night sky : How to improve your observing skills
This book is not for beginners. Nor is it for experts – instead it addresses the needs of practical amateur astronomers who want to make the jump to the new challenges of serious visual observing. Second Steps in Observational Astronomy begins by teaching you, as an amateur astronomer, to use the most important tool you have: your eyes. Visual observing is very definitely a skill that can be learned. Of course it is important to have your other optical equipment – telescope and accessories – set up and operating as perfectly as possible. This book describes how. After these vital preliminaries, subsequent chapters include a series of observing challenges that will entertain you and push your observing skills to continually higher levels of excellence for years to come. Take a tour of the solar-system as you never viewed it before, then beyond into the realm of deep space – using just your own eyes to reveal more detail than you ever thought possible.
Astronomical image and data analysis
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 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.
