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.
A sweeping tour of the galaxies, from our Milky Way to infinity. Galaxies are glittering islands in the Universe, interwoven in the web of Dark Matter. From Earth's mountaintops enormous telescopes peer deep beyond the Milky Way, while space telescopes locate majestic images, and through seemingly miraculous technology, capture them for us to look at and learn with amazement. Featuring the most recent, best, and even startling images with detailed captions highlighting accessible text, Galaxies shows the restless universe beyond our atmosphere. Photographs are from more than 30 of the world's largest ground-based telescopes, including the largest to date, the European Southern Observatory's Very Large Telescope in Chile. Images are also featured from the Hubble Space Telescope, which has continued to operate long past its expected life and to astound and astonish stargazers worldwide.

Galaxies: A Very Short Introduction by John Gribbin Pdf
In this fascinating Very Short Introduction, popular science writer John Gribben tells the story of our growing understanding of galaxies, from the days before Galileo to our present-day observations of our many hundreds of millions of galactic neighbors. Not only are galaxies fascinating astronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own "Milky Way" Galaxy in detail, from the different kinds of stars that are born within it, to the origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxies collide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter. John Gribbin is one of the best-known current popular science writers. His many books include the acclaimed The Universe: A Biography, In Search of Schrodinger's Cat, and Science: A History. He has written for many newspapers and regularly contributes to radio and television documentaries and debates, and also writes science fiction novels. He formerly worked for Nature and New Scientist and is presently a Visiting Fellow in Astronomy at the University of Sussex. 1. A Very Short Introduction 2. The Great Debate 3. Our Island 4.

Probing Galaxy Evolution by Unveiling the Structure of Massive Galaxies Across Cosmic Time and in Diverse Environments by Timothy Weinzirl Pdf
Awarded the American Astronomical Society (AAS) Rodger Doxsey Travel Prize, and with a foreword by thesis supervisor Professor Shardha Jogee at the University of Texas at Austin, this thesis discusses one of the primary outstanding problems in extragalactic astronomy: how galaxies form and evolve. Galaxies consist of two fundamental kinds of structure: rotationally supported disks and spheroidal/triaxial structures supported by random stellar motions. Understanding the balance between these galaxy components is vital to comprehending the relative importance of the different mechanisms (galaxy collisions, gas accretion and internal secular processes) that assemble and shape galaxies. Using panchromatic imaging from some of the largest and deepest space-based galaxy surveys, an empirical census of galaxy structure is made for galaxies at different cosmic epochs and in environments spanning low to extremely high galaxy number densities. An important result of this work is that disk structures are far more prevalent in massive galaxies than previously thought. The associated challenges raised for contemporary theoretical models of galaxy formation are discussed. The method of galaxy structural decomposition is treated thoroughly since it is relevant for future studies of galaxy structure using next-generation facilities, like the James Webb Space Telescope and the ground-based Giant Magellan Telescope with adaptive optics.

The Interstellar Medium in Galaxies by J.M. van der Hulst Pdf
The Interstellar Medium in Galaxies is a collection of seven reviews covering the following constituents of the interstellar medium: dust, molecular gas, neutral atomic hydrogen, ionized hydrogen, and hot gas, and covering the abundances of heavy elements in the interstellar medium and the role of star formation. The reviews not only provide a good background in these subjects, but also describe in detail the most recent advances in the area and discuss the current problems in the field. The properties of the different constituents of the interstellar medium are discussed within the perspective of the difference in properties of the parent galaxies and the environment. The interplay between star formation and the characteristics of the interstellar medium is also discussed in detail. This volume provides very up-to-date material on the subject of the interstellar medium in galaxies and is useful both as a basic reference for professional scientists in this field and as an introductory book for astronomers who want to familiarize themselves with this field. This volume can also serve as an accompanying text book for graduate courses on the interstellar medium.
Delineating the huge strides taken in cosmology in the past ten years, this much-anticipated second edition of Malcolm Longair's highly appreciated textbook has been extensively and thoroughly updated. It tells the story of modern astrophysical cosmology from the perspective of one of its most important and fundamental problems – how did the galaxies come about? Longair uses this approach to introduce the whole of what may be called "classical cosmology". What’s more, he describes how the study of the origin of galaxies and larger-scale structures in the Universe has provided us with direct information about the physics of the very early Universe.
The Physics of Galaxy Formation by Claudia Del P. Lagos Pdf
This thesis addresses two of the central processes which underpin the formation of galaxies: the formation of stars and the injection of energy into the interstellar medium from supernovae, called feedback. In her work Claudia Lagos has completely overhauled the treatment of these processes in simulations of galaxy formation. Her thesis makes two major breakthroughs, and represents the first major steps forward in these areas in more than a decade. Her work has enabled, for the first time, predictions to be made which can be compared against new observations which probe the neutral gas content of galaxies, opening up a completely novel way to constrain the models. The treatment of feedback from supernovae, and how this removes material from the interstellar medium, is also likely to have a lasting impact on the field. Claudia Lagos Ph.D. thesis was nominated by the Institute for Computational Cosmology at Durham University as an outstanding Ph.D. thesis 2012.
