Galaxy Formation and Evolution

Autor: Houjun Mo , Frank Van Den Bosch , Simon White

The rapidly expanding field of galaxy formation lies at the interface between astronomy, particle physics, and cosmology. Covering diverse topics from these disciplines, all of which are needed to understand how galaxies form and evolve, this book is ideal for researchers entering the field. Individual chapters explore the evolution of the Universe as a whole and its particle and radiation content; linear and nonlinear growth of cosmic structure; processes affecting the gaseous and dark matter components of galaxies and their stellar populations; the formation of spiral and elliptical galaxies; central supermassive black holes and the activity associated with them; galaxy interactions; and the intergalactic medium. Emphasizing both observational and theoretical aspects, this book provides a coherent introduction for astronomers, cosmologists, and astroparticle physicists to the broad range of science underlying the formation and evolution of galaxies.

Galaxies

Autor: Françoise Combes

Número de Páginas: 308

Les galaxies, vastes ensembles d’étoiles, de gaz et de poussières, vivant au sein des halos de matière noire, n’ont été identifiées comme des mondes à part que dans les années 1920. Depuis, les techniques d’observation modernes ont permis de faire des découvertes essentielles. Galaxies décrit tout d’abord les diverses morphologies et les catégories de galaxies existantes, permettant de mieux comprendre leur formation et leur évolution (à travers la séquence de Hubble ou le diagramme couleur-magnitude). Il étudie par la suite les principales propriétés de notre galaxie, la Voie lactée, ainsi que celles des galaxies de type précoce (sphéroïdales) ou tardif (spirales). Il analyse également les processus de fusion et les interactions entre galaxies, primordiaux dans la formation et l’évolution des galaxies, la formation des étoiles et la constitution des trous noirs, avant de finalement traiter de l’histoire cosmique de la formation des galaxies.

Galaxy Formation

Autor: Malcolm Longair

Número de Páginas: 1481

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.

Galaxies

Autor: Francoise Combes

Número de Páginas: 290

Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is still unclear, they stop forming stars and quietly end in the red sequence, as spheroids. This transformation may be due to galaxy interactions, or because of the feedback of active nuclei, through the energy released by their central super-massive black holes. These mechanisms could explain the history of cosmic star formation, the rate of which was far greater in the first half of the Universes life. Galaxies delves into all of these surrounding subjects in six chapters written by dedicated, specialist astronomers and researchers in the field, from their numerical simulations to their...

An Astronomical Life – Observing the Depths of the Universe” Though science as a subject can be di?cult, what has been more important for me is that its practice can also be rewarding fun! This book is crafted to expose the reader to the excitement of modern observational cosmology through the study of galaxy evolution over space and cosmic time. Recent extragalactic research has led to many rapid advances in the ?eld. Even a suitable skeptic of certain pronouncements about the age and structure of the Universe should be pleased with the large steps that have been taken in furthering our understanding of the Universe since the early 1990’s. My personal involvement in galaxy research goes back to the 1960’s. At that point, galaxies were easily recognized and partially understood as organized c- lections of stars and gas. What their masses were presented a problem, which I supposed would just fade away. But fade it didn’t. Distant active nuclei and quasars were discovered in the mid-1960’s. A c- mon view of QSOs was that they have large redshifts, but what use are they for cosmology or normal galaxy astrophysics? I shared that conclusion. My expec- tions fell below their ...

Deep Millimeter Surveys: Implications For Galaxy Formation And Evolution

Autor: David H Hughes , James D Lowenthal

Número de Páginas: 223

The arrival of large submillimeter and millimeter-wave detector arrays opened a new window on galaxy formation and evolution. The major new facilities now being designed or constructed, such as ALMA (MMA) and the Large Millimeter Telescope (LMT), will soon be expanding the horizons even farther.The Conference on “Deep Millimeter Surveys: Implications for Galaxy Formation and Evolution” drew together the major international groups working on submillimeter and millimeter-wave galaxies to discuss their relation to other galaxies both near by and in the early Universe, the role of the LMT and other new facilities in advancing the new field, and the implications of the new results and models for our understanding of galaxy formation and evolution. The resulting compendium of reports on observations, simulations, theory and interpretation, and instrumentation is the first book to present the new millimeter view of the early Universe thoroughly in a single volume.

Multiwavelength Mapping of Galaxy Formation and Evolution

Autor: Alvio Renzini , Ralf Bender

Número de Páginas: 520

The possibilities of astronomical observation have dramatically increased over the last decade. Major satellites, like the Hubble Space Telescope, Chandra and XMM Newton, are complemented by numerous large ground-based observatories, from 8m-10m optical telescopes to sub-mm and radio facilities. As a result, observational astronomy has access to virtually the whole electromagnetic spectrum of galaxies, even at high redshifts. Theoretical models of galaxy formation and cosmological evolution now face a serious challenge to match the plethora of observational data. In October 2003, over 170 astronomers from 15 countries met for a 4-day workshop to extensively illustrate and discuss all major observational projects and ongoing theoretical efforts to model galaxy formation and evolution. This volume contains the complete proceedings of this meeting and is therefore a unique and timely overview of the current state of research in this rapidly evolving field.

Mysteries of Galaxy Formation

Autor: Francoise Combes

Número de Páginas: 0

The mystery of how the galaxies formed is a complex and intriguing subject, involving several different theories and an understanding of many different phenomena. Françoise Combes outlines the context in which the Big Bang and the expansion of the universe occurred and the first ‘inhomogeneities’ from which arose the early structures of the universe. The author describes how, contrary to our everyday experience, space and time appear to be intimately connected. In astronomy, a telescope is a time machine. We can look today at distant galaxies and, although we describe them in the present tense, we are really seeing them in their youthful stages, now long over. Having outlined the evolution and structure of galaxies, black holes are introduced. What do we know about their origins and growth at the centers of galaxies? The author describes how scientists can observe and draw conclusions about black holes. Scenarios of both "top down" and "bottom up" galaxy formation are discussed, together with the relationship between red and blue galaxies and dwarf, elliptical, and spheroidal galaxies. The problem of dark matter is then addressed, including its relationship to visible matter...

Dwarf Galaxies: Keys to Galaxy Formation and Evolution

Autor: Polychronis Papaderos , Simone Recchi , Gerhard Hensler

Número de Páginas: 347

Dwarf galaxy research constitutes an extremely vibrant field of astrophysical research, with many long-standing questions still unsettled and new ones constantly arising. The intriguing diversity of the dwarf galaxy population, observed with advanced ground-based and space-borne observatories over a wide spectral window providing an unprecedented level of detail, poses new challenges for both observers and theoreticians. The aim of this symposium was to bring together these two groups to exchange ideas and new results on the many evolutionary aspects of and open issues concerning dwarf galaxies. The main topics addressed include: the birth of dwarf galaxies: theoretical concepts and observable relics across wavelengths and time, the morphological, structural and chemical evolution of dwarf galaxies, possible evolutionary connections between early-type and late-type dwarfs, the star formation history of dwarf galaxies and its dependence on intrinsic and environmental properties, the origin and implications of starburst activity in dwarf galaxies, the fate of dwarfish systems born out of tidally ejected matter in galaxy collisions.

Physics of the Formation and Evolution of Galaxies

Autor: Tsutomu Takeuchi

Número de Páginas: 0

This book introduces various physical processes related to the formation and evolution of galaxies, such as gravitation, electromagnetism, statistical physics, condensed matter, non-equilibrium processes, and relativity. Real data are analyzed using statistical methods and theoretical understanding. These topics give students and researchers in other fields a cross-sectional, interdisciplinary review. In particular, the author puts a great emphasis on multi-wavelength observations and surveys, which are now fundamental to understand the physics of any kind of cosmological and galactic comprehensive study. This is the first book to look at multi-wavelength surveys from the view of both observation and theory. This book is intended to be a standard guide to the physics of galaxy formation and evolution, which is popular in astrophysics but is not dealt with in detail in other books for young graduate students and non-experts in physics. Physical processes related to the formation and evolution of stars in galaxies are particularly mentioned from the view of multi-wavelength observations, which leads to an understanding of how the current universe has developed.

Panoramic Views of Galaxy Formation and Evolution

Número de Páginas: 570

"These proceedings of the first meeting of the Subaru International Conference Series held in December 2007 in Hayama, Japan, provide unique up-to-date overviews of the history of galaxy formation and the evolution of the universe. Fascinating and comprehensive observational results as well as many important theoretical achievements were presented by more than 150 active researchers from more than 15 countries and regions. The conference started off with results from recent cutting-edge observations of the very high-redshift universe extending into the cosmic reionization era, together with some theoretical interpretations and predictions for the first generation of galaxies. The history of mass distributions and structure formation at later cosmic times, including clusters of galaxies, was discussed extensively in presentations based on various panoramic survey data sets. Our aim was to showcase and understand the intrinsic galaxy-formation bias in the high-redshift universe and also the role of external environmental effects during the hierarchical assembly of galaxies into denser regions. Various populations of distant galaxies at different redshifts, discovered and studies by...

Fundamentals of Galaxy Dynamics, Formation and Evolution

Autor: Ignacio Ferreras

Número de Páginas: 200

Galaxies, along with their underlying dark matter halos, constitute the building blocks of structure in the Universe. Of all fundamental forces, gravity is the dominant one that drives the evolution of structures from small density seeds at early times to the galaxies we see today. The interactions among myriads of stars, or dark matter particles, in a gravitating structure produce a system with fascinating connotations to thermodynamics, with some analogies and some fundamental differences. Ignacio Ferreras presents a concise introduction to extragalactic astrophysics, with emphasis on stellar dynamics, and the growth of density fluctuations in an expanding Universe. Additional chapters are devoted to smaller systems (stellar clusters) and larger ones (galaxy clusters). Fundamentals of Galaxy Dynamics, Formation and Evolution is written for advanced undergraduates and beginning postgraduate students, providing a useful tool to get up to speed in a starting research career. Some of the derivations for the most important results are presented in detail to enable students appreciate the beauty of maths as a tool to understand the workings of galaxies. Each chapter includes a set of...

The Cosmic Evolution of Galaxy Structure

Autor: Christopher J. Conselice

Número de Páginas: 0

Galaxies are the fundamental units of cosmic matter that make up the universe and they change in remarkable ways over 13.7 billion years of cosmic time. We are just now discovering how galaxies we can see over these billions of years are evolving from small, star forming systems to larger, more massive and passive systems at later times. This book explains the structural evolution of galaxies, how we measure it, how these measurements change with time, and how observing this reveals important information about galaxy formation and evolution. It also explains the future of the field through the use of machine learning tools, and how galaxy structure can be used as a new approach to measure unique features of the universe, such as cosmological properties and parameters.

Globular Clusters - Guides to Galaxies

Autor: Tom Richtler , Søren Larsen

Número de Páginas: 448

The principal question of whether and how globular clusters can contribute to a better understanding of galaxy formation and evolution is perhaps the main driving force behind the overall endeavour of studying globular cluster systems. Naturally, this splits up into many individual problems. The objective of the Joint ESO-FONDAP Workshop on Globular Clusters - Guides to Galaxies was to bring together researchers, both observational and theoretical, to present and discuss the most recent results. Topics covered in these proceedings are: internal dynamics of globular clusters and interaction with host galaxies (tidal tails, evolution of cluster masses), accretion of globular clusters, detailed descriptions of nearby cluster systems, ultracompact dwarfs, formations of massive clusters in mergers and elsewhere, the ACS Virgo survey, galaxy formation and globular clusters, dynamics and kinematics of globular cluster systems and dark matter-related problems. With its wide coverage of the topic, this book constitutes a valuable reference of the scientific knowledge of the field.

Autor: Fatemeh Tabatabaei , Beatriz Barbuy , Yuan-sen Ting

Número de Páginas: 0

Our comprehension of the assembly and evolution of galaxies has witnessed remarkable advancements in recent years. While the Gaia spacecraft has provided unprecedented knowledge of the Milky Way's assembly, the launch of the James Webb Space Telescope (JWST) has propelled the study of galaxy evolution into an exciting new era. Early discoveries of JWST have revealed high-redshift galaxies that defy our expectations. These conundrums must be resolved through multi-wavelength observations, simulations, and theoretical models as emphasized in this volume, which contains a selection of papers presented at IAU Symposium 377, held about two years after the launch of JWST. These papers showcase studies of galaxy formation, evolution, interaction, chemical abundances and stellar populations from cosmic down to the Milky Way. These proceedings offer an updated view of recent advances and current problems and is suitable for both active researchers in the field and graduate students.

The Formation and Evolution of M33 as Revealed by Its Star Clusters

Autor: Izaskun San Roman

Número de Páginas: 138

This thesis represents the first wide-field photometric and spectroscopic survey of star clusters in the nearby late-spiral galaxy M33. This system is the nearest example of a dwarf spiral galaxy, which may have a unique role in the process of galaxy formation and evolution. The cold dark matter paradigm of galaxy formation envisions large spiral galaxies, such as the Milky Way, being formed from the merger and accretion of many smaller dwarf galaxies. The role that dwarf spiral galaxies play in this process is largely unclear. One of the goals of this thesis is to use the star cluster population of M33 to study its formation and evolution from its early stages to the present. The thesis presents a new comprehensive catalog of M33 star clusters, which includes magnitudes, colors, structural parameters, and several preliminary velocity measurements. Based on an analysis of these data, the thesis concludes that, among other things, the evolution of M33 has likely been influenced by its nearby massive neighbor M31.

Probing Galaxy Evolution by Unveiling the Structure of Massive Galaxies Across Cosmic Time and in Diverse Environments

Autor: Timothy Weinzirl

Número de Páginas: 249

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...

Galaxy Scaling Relations: Origins, Evolution and Applications

Autor: Luiz N. Dacosta , Alvio Renzini

Número de Páginas: 416

At close inspection every galaxy appears to have its own individuality.A galaxy can be warped, lop-sided, doubly-nucleated, boxy or disky, ... in its own specific, peculiar way. Hence, for a complete description, galaxy taxonomy may ask for finer and finer classification schemes. However, for some applications it may be more fruitful to let details aside and focus on some global properties of galaxies. One is then seeking to measure just a few quantities for each galaxy, a minimum set of globalobservables that yet captures some essential aspect of these objects. One very successful example of this approach is offered by the scaling rela tions of galaxies, the subject of the international workshop held at ESO head quarters in Garching on November 19-21, 1996. Discovered in the late 1970's, the Tully-Fisher relation for the spirals and the Faber-Jackson relation, or its more recent version the Fundamental Plane, for ellipticals have now become flourishing fields of astronomical research in their own right, as well as being widely used tools for a broad range of astronomical investigations. The work shop was designed to address three key issues on galaxy scaling relations, i.e.,...

Chemical Evolution of Galaxies

Autor: Francesca Matteucci

Número de Páginas: 237

The term “chemical evolution of galaxies” refers to the evolution of abundances of chemical species in galaxies, which is due to nuclear processes occurring in stars and to gas flows into and out of galaxies. This book deals with the chemical evolution of galaxies of all morphological types (ellipticals, spirals and irregulars) and stresses the importance of the star formation histories in determining the properties of stellar populations in different galaxies. The topic is approached in a didactical and logical manner via galaxy evolution models which are compared with observational results obtained in the last two decades: The reader is given an introduction to the concept of chemical abundances and learns about the main stellar populations in our Galaxy as well as about the classification of galaxy types and their main observables. In the core of the book, the construction and solution of chemical evolution models are discussed in detail, followed by descriptions and interpretations of observations of the chemical evolution of the Milky Way, spheroidal galaxies, irregular galaxies and of cosmic chemical evolution. The aim of this book is to provide an introduction to...

The Epoch of Galaxy Formation

Scientists in the late twentieth century are not the first to view galaxy formation as a phenomenon worthy of explanation in terms of the known laws of physics. Already in 1754 Kant regarded the problem as essentially solved. In his Univerlal Natural Hutory and Theory 0/ the H eaven$ he wrote; "If in the immesurable space in which all the suns of the Milky Way have formed themselves, we assume a point around which, through some cause or other, the first formation of nature out of chaoo began, there the largest mass and a body of extraordinary attraction will have arisen which has thereby become capable of compelling all the systems in the process of being formed within an enormous sphere around it, to fall towards itself as their centre, and to build up a system around it on the great scale . . . . Observation puts this conjecture almost beyond doubt. " More than 200 years later, a similar note of confidence was voiced by Zel'dovicb at an IAU symposium held in Tallin in 1911; "Extrapolating . . . to the next symposium somewhere in the early eighties one can be pretty sure that the question of the formation of galaxies and clusters will be solved in the next few years. " Perhaps...
