Available in PDF, EPUB and Kindle. Book excerpt: It is only several decades since galaxies were recognized as huge aggregations of matter in the universe which consist of myriads of stars and vast clouds of gas. The wide variety of shapes of galaxies is one of the wonders of the universe. Attempts to classify galaxies have continued since an early stage of study, when they were still called nebulae. The first step towards classification was a grouping of the patterns; the second step a systematic arrangement of various morphological types. Classification schemes that are in present use, such as Hubble's, are in the second group. These classifications are usually based on pattern recognition after a visual inspection of the photographic image of the galaxy, and is therefore qualitative and more or less subjective. Using surface photometry of galaxies, a technique which has advanced remarkably in recent years, photographs of galaxies taken in several colour bands can now be efficiently reduced to photometric data. Analysis of this data gives quantitative information on the luminosity and colour distribution for every element of galaxies. The Atlas of Selected Galaxies presents photographs taken with the Okayama 188 cm reflector and the Kiso 105 cm Schmidt telescope for the purpose of photometric analysis. A large number of illustration are given to demonstrate the way in which photographs of galaxies are reduced into quantitative data. These illustrations also show some representative results obtained in the course of the editors' work on the quantitative classification of galaxies. Part I, General Description of the Classification and Photometric Analyses, includes eight sections, whose authors all shared the photometric work and prepared the photographs. In Part II, The Atlas, the illustrations are arranged in sections corresponding to those in Part I. Part III includes tables of data for the atlas.

Download or read book Cosmic Collisions written by Lars Lindberg Christensen and published by Springer Science & Business Media. This book was released on 2010-04-07 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like no other telescope ever invented, the NASA/ESA Hubble Space Telescope has given us magnificent high resolution views of the gigantic cosmic collisions between galaxies. Hubble's images are snapshots in time and catch the colliding galaxies in different stages of collision. Thanks to a new and amazing set of 60 Hubble images, for the first time these different stages can be put together to form a still-frame movielike montage showing the incredible processes taking place as galaxies collide and merge. The significance of these cosmic encounters reaches far beyond aesthetics. Galaxy mergers may, in fact, be some of the most important processes that shape our universe. Colliding galaxies very likely, hold some of the most important clues to our cosmic past and to our destiny. It now seems clear that the Milky Way is continuously undergoing merging events, some small scale, others on a gigantic scale. And the importance of this process in the lives of galaxies is much greater than what was previously thought.

Download or read book A Photographic Atlas of Selected Regions of the Milky Way written by Edward Emerson Barnard and published by Cambridge University Press. This book was released on 2014-08-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edward Emerson Barnard's Photographic Atlas of Selected Regions of the Milky Way was originally published in two volumes in 1927. Together these volumes contained a wealth of information, including photographic plates of the most interesting portions of the Milky Way, descriptive text, charts, and data. Only 700 copies were printed, making the original edition a collector's item. Reproduced in print for the first time, this edition combines both volumes of Barnard's Atlas. It directly replicates Barnard's text, and contains high resolution images of the original photographic plates and charts, reordered so that they can be seen together. It also includes a biography of Barnard and his work, a Foreword and Addendum by Gerald Orin Dobek describing the importance of the Atlas and additions to this volume, and a pull-out section with a mosaic of all 50 plates combined in a single panorama.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the 4th International Conference on Data Analysis and Processing held in Cefalu' (Palermo, ITALY) on September 23-25 1987. The aim of this Conference, now at its fourth edition, was to give a general view of the actual research in the area of methods and systems for achieving artificial vision as well as to have an up-dated information of the current activity in Europe. A number of invited speakers presented overviews of statistical classification problems and methods, non conventional archi tectures, mathematical morphology, robotic vision, analysis of range images in vision systems, pattern matching algorithms and astronomical data processing. Finally a survey of the discussion on the contribution of AI to Image Analysis is given. The papers presented at the Conference have been subdivided in four sections: knowledge based approaches, basic pattern recognition tools, multi features system based solutions, image analysis-applications. We must thank the IBM-Italia and the Digital Equipment Corpo ration for sponsoring this Conference. We feel that the days spent at Cefalu' were an important step toward the mutual exchange of scientific information within the image processing community. v. Cantoni Pavia University V.
