Available in PDF, EPUB and Kindle. Book excerpt: Une galaxie est un système complexe au sens où, autant des phénomènes se produisant à l'échelle du milieu interstellaire, comme des explosions de supernovæ ou l'activité d'un trou noir supermassif, que des interactions entre galaxies au sein de groupes ou d'amas, comme l'effeuillage par effet de marée ou par effet de bélier, influencent et conditionnent l'évolution de la galaxie dans son ensemble. Comme les processus œuvrant dans de tels systèmes font intervenir une gamme d'échelle de temps et de distance considérable, allant de l'étoile individuelle aux amas de galaxies tout entier, leur modélisation constitue un immense défi qui ne peut être relevé ni par une approche purement analytique ni par l'entremise de techniques exclusivement numériques.Cette thèse, à l'interface entre modèles semi-analytique et analyse de simulations numériques, se concentre sur l'étude de l'effeuillage des étoiles des galaxies satellites par effet de marée et sur les rétro-actions induites par les supernovæ.Ce manuscrit présente, d'une part, un modèle d'occupation des halos permettant de contraindre la masse d'étoiles perdue par les galaxies satellites depuis leur entrée dans leur groupe ou leur amas ainsi qu'un modèle d'effeuillage impulsif prédisant la masse stellaire arrachée aux satellites. Ce dernier est confronté, par le truchement du modèle d'occupation des halos, aux observations des fonctions de masses des groupes et des amas.Il expose, d'autre part, l'étude des rétro-actions des supernovæ implémenté dans les simulations numériques du projet NIHAO, conduite en séparant en différentes composantes le gaz des simulations et en comptabilisant les échanges entre ces dernières, laquelle a permis de mettre en évidence trois processus distincts par le biais desquels les supernovæ réduisent ou suppriment la formation stellaire.Enfin, il détaille les améliorations techniques et scientifiques apportées au modèle semi-analytique GalICS.

This book was released on 2007-05-17 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This last decade has witnessed a revolution in our observations of galaxies; in particular deep imaging with HST and spectroscopy with 10m-class ground-based telescopes have uncovered many objects that are difficult to place along the Hubble sequence. High resolution spectroscopy of extremely faint objects has enabled the study of the kinematic evolution and, hence, the mass assembly of galaxies to unprecedented look-back times for direct comparison with cosmological structure formation scenarios. Thus, it is now possible to study all three aspects of galaxy evolution - their morphological-dynamical, chemical and spectral evolution out to redshift larger than six, exploring more than 95% of the age of the universe. These Proceedings of the IAU Symposium 235 report the considerable progress made in recent years on galaxy formation and evolution, and look forward to the expected breakthroughs in the domain of remote galaxies, with ALMA, the ELT and the next generation space telescopes.

Available in PDF, EPUB and Kindle. Book excerpt: Evolution of Stars and Stellar Populations is a comprehensive presentation of the theory of stellar evolution and its application to the study of stellar populations in galaxies. Taking a unique approach to the subject, this self-contained text introduces first the theory of stellar evolution in a clear and accessible manner, with particular emphasis placed on explaining the evolution with time of observable stellar properties, such as luminosities and surface chemical abundances. This is followed by a detailed presentation and discussion of a broad range of related techniques, that are widely applied by researchers in the field to investigate the formation and evolution of galaxies. This book will be invaluable for undergraduates and graduate students in astronomy and astrophysics, and will also be of interest to researchers working in the field of Galactic, extragalactic astronomy and cosmology. comprehensive presentation of stellar evolution theory introduces the concept of stellar population and describes "stellar population synthesis" methods to study ages and star formation histories of star clusters and galaxies presents stellar evolution as a tool for investigating the evolution of galaxies and of the universe in general

This book was released on 2020-08-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a broad overview of what we currently know about the Origin and Evolution of the Universe. The goal is to be scientifically comprehensive but concise. We trace the origins from the Big Bang and cosmic expansion, to the formation of galaxies, heavy elements, stars and planets as abodes for life. This field has made stunning progress since the first edition of this book. At that time, there were no known planets outside of our own Solar System (compared with the many thousands currently being studied). The origin of massive black holes was pure speculation (compared with the very recent detection of the first gravitational waves from space, produced by the cataclysmic merger of two surprisingly large black holes). And the most important energy in the Universe, now known as the Dark Energy which is accelerating the expansion, had not been discovered. We aim to bring lay readers with an interest in science 'up to speed' on all of these key discoveries that are part of the panorama of cosmic evolution, which has ultimately lead to our existence on Earth.
Download or read book The Evolution of the Universe written by G. Börner and published by . This book was released on 1997-08-26 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrophysicists and astronomers have succeeded in formulating a consistent picture of the expanding universe that rests on highly symmetric solutions of Einstein?s theory of gravitation coupled to a single matter model. This model seems to be valid from a fraction of a second after the big bang up to the present epoch, and it explains the synthesis of the light nuclei, the existence and properties of the microwave background, as well as the global average properties of matter distribution. It also allows the accommodation of such global phenomena as the overall expansion of the system of galaxies, the number counts of celestial objects, the evolutionary effects in quasars and radio galaxies, as well as the fact that the age information obtained from meteorites, minerals, and stars agrees well with the expansion rate. This "standard model" actually includes a wide range of possible cosmological models, which differ in the values of various ? in principle, measurable ? parameters (e.g., the expansion velocity, the deceleration of the galaxy system, the mean density of matter and radiation, etc.), but which share some basic properties. Cosmological models describe a world that expands from a hot big bang that is globally homogeneous, isotropic, and in a thermochemical equilibrium, and which has developed inhomogeneous structures, e.g., galaxies from initial small-density fluctuations through gravitational instability. This volume is the record of intense discussions between physicists, astronomers, and astrophysicists. It focuses on four main issues: How do galaxies form? How well do we understand the formation of large-scale structures? What is the relation between cosmology and fundamental theories of particle physics? What do we know about the global properties of the universe? Among the topics illuminated from various perspectives are the nature and distribution of dark matter in the universe, the possible discrepancy in recent astronomical data between the age and the expansion time of the universe, and speculations about the very early universe. This volume provides not only an in-depth status report on cosmology, but also defines areas where progress is to be-expected in the near future. Goal of this Dahlem Workshop: to examine conceptual, theoretical, and observational problems of the formation of structure in the universe.
