Available in PDF, EPUB and Kindle. Book excerpt: Galaxies are large systems of stars, some of which contain interstellar gas and dust. They also contain much invisible matter, which may be in the form of weakly interacting elementary particles. In this introductory textbook, the first chapter introduces the study of galaxies. This is followed by two chapters on observations of galaxies, including our own. There are then three chapters on galactic structure: the manner in which motions of stars determine galactic shape, the determination of galactic masses, and the structure of discs in spirals. Galactic evolution, especially changes in chemical composition over time, is covered. The book concludes with a discussion of the origin of galaxies and their relation to more general questions in cosmology. The book includes mathematical presentation where this enables the discussion to be quantitative.

Available in PDF, EPUB and Kindle. Book excerpt: It is sometimes said that astronomy is the crossroads of physics. In the same spirit, it can forcefully be argued that galaxies are the crossroads of astronomy. Internal pro ces ses within galaxies involve all of the fundamental components of astrophysics: stellar evolution, star formation, low-density astrophysics, dynamics, hydrodynamics, and high-energy astrophysics. Indeed, one can hardly name an observational datum in any wavelength range on any kind of celestial object that does not provide a useful clue to galaxy formation and evolution. Although internal processes in galaxies until recently occupied most of our attention, we now know that it is also vital to relate galaxies to their environment. How galaxies congregate in larger structures and are in turn influenced by them are crucial questions for galactic evolution. On a grander level we have also come to regard galaxies as the basic building blocks of the universe, the basic units whereby the large scale structure of the universe is apprehended and quantified. On a grander level still, we also believe strongly that galaxies are the direct descendents of early density irregularities in the Big Bang. Galaxy properties are now viewed as providing a crucial constraint on the physics of the Big Bang and a vital link between the macroscopic and microscopic structure of the universe.

Download or read book Dynamical Evolution of Disk Galaxies written by Frank Hohl and published by . This book was released on 1970 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer model for isolated disks of stars is presented and is used to study the self-consistent motion of large numbers of point masses as they move in the plane of the galactic disk. The Control Data 6600 computer system at the Langley Research Center was used to integrate the equations of motion for each star for systems containing from 50,000 to 200,000 stars. Any initially cold balanced disk was found to be violently unstable. A sufficient amount of velocity dispersion will stabilize all small-scale disturbances. However, most disks investigated were found to be unstable against slowly growing long-wavelength modes, and after about two rotations the disks tended to assume a bar-shaped structure. It was also found that the final mass distribution for most disks could be closely approximated by an exponential variation irrespective of the initial mass distribution. To study the development of spiral structure, the model was modified to include a fixed central force similar to that in the Schmidt model of the Galaxy. The mass of the stars in the disk was taken to be from 5 to 50 percent of the total mass of the Galaxy. The evolution of a number of initial distributions of stars was investigated. The results of the calculation gave a velocity dispersion for the disk stars which was about 50 percent larger than the value of about 30 km/sec found from observation of stars in the solar neighborhood. For some of the disks investigated, a pronounced spiral structure remained even after 8.5 rotations.

Available in PDF, EPUB and Kindle. Book excerpt: From June 7-9, 1995, the European Southern Observatory (ESO) and the Max Plank Institut fiir Astrophysik (MPA) jointly held the Workshop on Spiral Galaxies in the Near-IR. This meeting took place at the ESO headquarters in Garching bei Miinchen, Germany. The weather waschanging, with the biergarten closed, but that did not stop 85 people from allover the world from attending the meeting. The three days were intensive, with talks and coffee and posters from 9 am to 6 pm, and very productive indeed for everyone. The topics covered the stellar populations of the Milky Way and other more distant spirals, the role of dust, the dynamics of spiral galaxies, and the nuclear activity seen at near-IR wavelengths. This volume presents the original contributions from the participants, including several papers that review the state-of-the-art knowledge in these various subjects. The editors would like to thank first and foremost Christina Stoffer, for she took care of everything. The meeting would not have been so successful without her expertise and efficiency. We are deeply indebted to the directors of MPA and ESO Science, Simon White and Jacqueline Bergeron, for their support and encouragement. We would also like to thank the other members of the scientific organizing committee: R. Genzel, K. Freeman, A. Moorwood, S. White, M. Rieke and E. Athannasoula, for their advice with the organization of the program. We also thank G. Rieke, R. Genzel, L. Athannasoula, A. Renzini and R.

Download or read book Galaxy Evolution Connecting the Distant Universe with the Local Fossil Record written by Monique Spite and published by Springer Science & Business Media. This book was released on 1999 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date review of the basic elements directly connected to the evolution of galaxies. Owing to recent advances in observational astronomy and astrophysics, data has recently become available about remote galaxies, which are consequently in the first stages of their evolution. It is therefore essential to link these data to the observation of very old populations in our own Galaxy, which are the remnants of the populations which existed in the first stages of galactic evolution. In this meeting, the relationship between these two different points of view is emphasized in the texts presented by well-known specialists as well as by young researchers active in the field. The difficulties of the problem and the remaining uncertainties are discussed.
Download or read book Structure and Dynamics of Elliptical Galaxies written by Tim de Zeeuw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: IAU Symposium 127 was held in Princeton on May 28-31, 1986, at the Institute for Advanced Study. There were 150 participants from 19 countries. This was the first IAU Symposium devoted exclusively to elliptical galaxies. The last decade has been a period of exceptionally rapid progress regard ing our understanding of elliptical galaxies, driven on the observational side by a wealth of new photometric and spectroscopic data, and on the theoretical side by the recognition that ellipticals are slowly rotating triaxial systems, instead of rotationally flattened bodies. The 30 invited speakers reviewed all aspects of this progress, its consequences, and the major outstanding problems. Nearly 80 poster contributions were displayed for the duration of the meeting. These contained many of the most recent developments. The first part of these Proceedings contains the written versions of the invited reviews and the summary, in the order of their presentation. The accompanying discussions are based on the written versions of questions and answers as handed in by the participants. The second part of this book is devoted to the poster contribu tions. They have been grouped in a thematic order, proceeding from morphology to theory. Indices of objects, subjects, and names are provided. Unfortunately, none of the invited participants from the USSR were able to attend the Symposium. The Proceedings include the written versions of the planned contributions by Popov and Polyachenko.
