This book was released on 2015-11-21 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses the evolution of galaxies through the study of the morphology, kinematics, and star formation properties of a sample of nearby galaxies. The main body of the thesis describes the kinematic observations with the GHaFAS Fabry-Perot instrument on the William Herschel Telescope of a sample of 29 spiral galaxies. The work is closely related to the Spitzer Survey of Stellar Structure in Galaxies, and uses the mid-infrared data of that survey to determine key parameters of the galaxies studied. From these data, important results are obtained on streaming and other non-circular motions in galaxies, on the distribution and rates of star formation, and on how correlations of these parameters and of the rotation curve shape with basic galaxy parameters yield clues on the evolutionary processes taking place in disk galaxies.

This book was released on 1984 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have conducted a detailed study of the dynamics of the neutral hydrogen gas in the bright northern barred spiral galaxy NGC 3359. Observations of the 21 cm line at the Very Large Array have been reduced to give single-channel maps with a spatial resolution of 18", and a velocity resolution of 25 km/s. The acquisition, calibration, and reduction of the data are discussed in some detail. Maps of the integrated column density and mean velocity of the atomic hydrogen, derived from the channel maps, provide the principal data for an investigation of the dynamics associated with the spiral structure of the galaxy. On scales comparable to the resolution of this survey, approximately 1 kpc at the distance of NGC 3359, the gas is broken up into a somewhat chaotic distribution of local maxima and minima. However, on larger scales the column density shows a smooth, grand design spiral pattern with two principal spiral arms. The extent and density of these two arms are roughly equal in the 21 cm map, unlike the optical image. These neutral hydrogen arms are very well correlated with the positions of H II regions. The observed velocity field of NGC 3359 shows large kinematical deviations from simple rotation. The locations of the disturbances are closely correlated with the optical and 21 cm spiral structure, and indicate that significant spiral streaming motions are present in the arms. We have performed numerical modeling of the galaxy, using the well-known "beam scheme" hydrodynamical code, to attempt to reproduce the observed kinematics. Two types of model have been employed. In the first, the spiral structure is driven by an inhomogeneous, triaxial bar, whose density distribution is determined from near infrared surface photometry. The alternative is an oval distortion of the underlying disk surface density. In models which depend solely on the triaxial bar, the kinematical perturbations in the galaxy's outer regions are far too weak, relative to those near the bar. The oval distortion models fit the observed velocities much more accurately. We conclude that the spiral structure in NGC 3359 cannot be driven entirely by the nonaxisymmetric force produced by the observed optical bar.

Available in PDF, EPUB and Kindle. Book excerpt: Unique in its breadth of coverage and level of presentation, this revised textbook provides more on the nature of galaxies, extragalactic objects, the large-scale structure of the Universe, and cosmology than is available in general textbooks on astronomy. It remains, however, accessible to advanced undergraduate students. One or more chapters are devoted to each of the following: the classification and morphology of galaxies; the galactic interstellar medium; galactic kinematics; elliptical, spiral, and barred spiral galaxies; the interactions between galaxies; extragalactic radio sources, quasars and their line spectra, and other active galactic nuclei; the formation of galaxies; the Universe as a whole; and cosmology.

Download or read book Spiral Structure in Galaxies written by Marc S Seigar and published by Morgan & Claypool Publishers. This book was released on 2017-06-29 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does it happen that billions of stars can cooperate to produce the beautiful spirals that characterize so many galaxies, including ours? This book reviews the history behind the discovery of spiral galaxies and the problems faced when trying to explain the existence of spiral structure within them. In the book, subjects such as galaxy morphology and structure are addressed as well as several models for spiral structure. The evidence in favor or against these models is discussed. The book ends by discussing how spiral structure can be used as a proxy for other properties of spiral galaxies, such as their dark matter content and their central supermassive black hole masses, and why this is important.

Book excerpt: Vistas in Astronomy, Volume 14: Astrometry - Theoretical Astrophysics – Instrumentation – Spectroscopy – Galactic Structure – Galaxies focuses on the methods, processes, and technologies used in astronomy. The selection first discusses the calculations of eclipse and lunar features. The method of computation, symbols that are used, and limit of the shadow path are explained. The book also looks at the spectral classification through seven-color photometry. The effects of chemical composition and interstellar absorption; pseudo-continua of dwarf stars; introduction of linear combinations of color indices; and variable and emission-line stars are discussed. The book also scrutinizes element abundance in O- and early B-stars. The method of fine analysis, observations, and fine analyses of normal and peculiar stars are explained. The book also examines the spiral structure and kinematics of the galaxy from a study of the H II regions. The study of the Doppler-Fizeau effect of the ionized interstellar hydrogen; extension of interference methods to the study of the structure of extragalactic nebulae; and structure and dynamics of barred spiral galaxies are discussed. The selection is a valuable source of information for readers interested in astronomy.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of galaxies, the building blocks of the Universe has advanced significantly in recent years. New observations from ground- and space-based telescopes, the discovery of dark matter, and new insights into its distribution have been instrumental in this. This textbook provides graduate students with a modern introduction to the gravitationally determined structure and evolution of galaxies. Readers will also benefit from detailed discussions of the issues involved in the process of modeling complex stellar systems. Additionally, the text provides an accessible framework for interpreting observations and devising new observational tests. Based on the author's extensive teaching experience, this second edition features an up-to-date view of basic phenomenology, a discussion of the structure of dark halos in galaxies, the dynamics of quasi-relaxed stellar systems and globular clusters, galaxies and gravitational lensing and an introduction to self-gravitating accretion disks. Extended problem sets are available from the accompanying resources website: www.cambridge.org/9781107000544.
