Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a series of lectures delivered at the 2nd course of the International School of Astrophysics at the "Ettore Majorana" Centre for Scientific Culture in Erice (Sicily) from June 22 to July 9, 1974. The course was jointly planned by L. Woltjer and myself and was fully supported by a grant from the NATO Advanced Study Institute Programme. It was organized with the aim of providing students and young researchers with an up to date account of the structure and evolution of galaxies and was attended by 94 participants from 20 countries. The study of galaxies is one of the most important areas of contemporary astrophysics both for its intrinsic interest and because it is a prerequisite to a quantitative understanding of the structure of the universe. Recently, a qualitatively new under standing has become available through both observational andtheore tical progress. On the observational side, new techniques applied at the large optical telescopes and, in particular, the impressive results obtained wi. th the high resolution radio telescopes have made it possible to obtain a detailed mapping of the structure of galaxies other than our own. At the same time, new theoretical insights and the availability of powerful computers to construct models holds out the hope that a full understanding of the structur. es of galaxies may be within our reach.

Available in PDF, EPUB and Kindle. Book excerpt: This research monograph presents a new dynamical framework for the study of secular morphological evolution of galaxies along the Hubble sequence. Classical approaches based on Boltzmann’s kinetic equation, as well as on its moment-equation descendants the Euler and Navier-Stokes fluid equations, are inadequate for treating the maintenance and long-term evolution of systems containing self-organized structures such as galactic density-wave modes. A global and synthetic approach, incorporating correlated fluctuations of the constituent particles during a nonequilibrium phase transition, is adopted to supplement the continuum treatment. The cutting-edge research combining analytical, N-body simulational, and observational aspects, as well as the fundamental-physics connections it provides, make this work a valuable reference for researchers and graduate students in astronomy, astrophysics, cosmology, many-body physics, complexity theory, and other related fields.

Download or read book Formation and Evolution of Galaxy Bulges IAU S245 written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2008-09-04 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulges lie at the heart of most galaxies, the building blocks of our universe. With a selection of reviews and topical presentations, IAU Symposium 245 provides an up-to-date overview of our knowledge on galaxy bulges, and a concise introduction to all current research on the subject. The structure, dynamics, and stellar populations of galaxy bulges, both near and far, are analysed through state-of-the-art observations. The leading models for the formation and evolution of galaxy bulges are described in detail, and the constraints observations put on these are dissected. Particular emphasis is placed on exploring evidence for both hierarchical merging and secular processes. Special attention is also devoted to disentangling the complex web relating galaxy bulges and central supermassive black holes, and on the lessons learned from our exquisite knowledge of the bulge of our own Milky Way. This volume is the best one-stop reference on galaxy bulges currently available.

Available in PDF, EPUB and Kindle. Book excerpt: From 12 April to 14 April 1988, 120 of Gerard and Antoinette de Vaucouleurs's friends and colleagues gathered at the Institut d' Astrophysique in Paris to cel ebrate Gerard's 70th birthday and his remarkable career in Astronomy. The gathering also honored the memory of Antoinette (who died 29 August 1987 after a long illness) and her own no less remarkable career. This volume collects the 24 invited review papers and the 60 contributed poster papers presented at the meeting. Gerard de Vaucouleurs Gerard de Vaucouleurs was born on 25 April 1918 in Paris, where he spent his boyhood. He became an active amateur astronomer in the early 1930's, making extensive observations of Mars, Jupiter, and variable stars (including the bright supernova of 1937 in IC 4182). He also began life-long interests in astronomical photography and galaxy cataloguing during this period. In 1939, he met the director of the Paris transport system and an equally avid amateur astronomer, Julien Peridier. De Vaucouleurs worked at Peridier's private observatory at Le Houga in southwestern France on and off throughout the next decade. His undergraduate work was in mathematics, astronomy, and experimental physics; this, combined with his interest in observational astronomy, formed his life-long empirical approach to science. After spending 18 months in the French army early in 1939 - 41, Gerard returned to the Peridier observatory and then, in 1943, to his studies at the Sorbonne, where he met Antoinette.

Available in PDF, EPUB and Kindle. Book excerpt: Giant Molecular Clouds in the Galaxy: Third Gregynog Astrophysics Workshop covers the proceedings of the 1977 Third Gregynog Astrophysics Workshop on Giant Molecular Clouds (GMC), held at the University of Wales. This book is organized into 11 parts encompassing 33 chapters. After a brief introduction to the significant features of GMC, this book goes on examining radio, millimeter, and galactic center observations of GMC, along with their infrared properties and kinematics. Other parts deal with the water sources in GMC; time variation in interstellar water masers; and the relation of HII regions to molecular clouds. The remaining parts discuss the evolution of interstellar molecular clouds and the role of magnetic fields in the collapse of protostellar gas clouds. These parts also cover the chemistry of interstellar molecules containing nitrogen and the search for other planetary systems. This book will prove useful to cloud scientists, physicists, astronomers, and researchers.
Download or read book The Letters and Papers of Jan Hendrik Oort written by J.K. Katgert-Merkelijn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The astronomer Jan Hendrik Oort (1900-1992) left behind an extensive collection of notes and correspondence, both on his research and on matters that concerned him in a variety of official functions. Upon Oort's death, the collection was augmented by more personal papers, letters, journals, and diaries. The resulting collection forms a rich source of information on many aspects of twentieth-century astronomy, in which Oort played such an important role. The scientific and personal material covers the entire span of time from Oort's early youth until his death. To make these papers accessible to a wide circle of users, the collection has now been catalogued and described; the result is presented in this volume. A name index and a subject index have been added to facilitate access. The inventory is accompanied by a short biographical sketch, and a number of photographs, mostly relating to Oort's career as a scientist. The original papers themselves are archived in the Leiden University Library.

Download or read book Galactic and Intergalactic Magnetic Fields written by R. Beck and published by Springer Science & Business Media. This book was released on 1990-04-30 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Symposium, the first devoted entirely to the measurement and the role of magnetic fields in the non-solar Universe, was held in Heidelberg, on June 19-23, 1989. The meeting began with review talks on magnetic phenomena near the solar photosphere, corona, and in stellar winds, since these nearby "laboratories", studied for many years, provide much of the prior knowl edge of magnetic effects in astrophysical plasmas. The Symposium contained presentations of considerable new work concerning the role of magnetic fields in accretion disks, bipolar outflows, and related magnetic phenomena in molecular clouds and star forming regions. Both observa tions and related theory of the large-scale magnetic fields in the Milky Way were covered, in addition to a session on the more general theme of magnetohydrodynamics of galactic magnetic fields. Dynamo mechanisms were discussed in considerable detail. It was apparent that recent observational data on polarized emission from external galaxies are now of sufficiently high quality that meaningful tests of large-scale field amplification, and of ideas on the origin of galactic magnetic fields, can be undertaken. Both new observations and numerical simulation work were described in the context of active galaxy nuclei, supernova remnants, radio source jets and extended lobes, and also in the environment of galaxy clusters. Recent large-scale computer simulations incorporating magnetic fields in star formation, radio source jets, and many other phenomena were presented, and much of this was very new.

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.
