Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse est consacrée à l'étude du couplage entre l'évolution dynamique et spectro-photométrique des galaxies isolées à disque, via des simulations numériques "N-corps". Nous présentons une technique de calibration photométrique des simulations incluant étoiles, gaz et formation stellaire avec un modèle de synthèse de populations stellaires et en tenant compte de l'extinction par les poussières. Suite à la description des techniques numériques utilisées, deux études sont présentées montrant l'intérêt d'une telle méthode pour étudier simultanément l'évolution dynamique et photométrique des galaxies. La première consiste en une analyse morphologique détaillée de l'évolution séculaire d'une galaxie isolée à disque. Les effets de la formation d'une barre stellaire et de l'épisode de formation stellaire associé sur les propriétés globales (luminosités, indices de couleur, rayons isophotaux, ellipticité de la barre) sont analysés à partir des images simulées de cette galaxie dans les bandes photométriques B, R, H et K. Les différences morphologiques en fonction de la longueur d'onde et en comparaison avec la distribution de masse sont systématiquement quantifiées, de même que les effets de l'extinction. Nous montrons par exemple que les propriétés dynamiques des régions délimitées par les rayons isophotaux dépendent à la fois de la longueur d'onde et du niveau d'activité de la formation stellaire. La seconde étude est dédiée au problème de la détermination de la longueur de barre et de la position des résonances dynamiques dans les galaxies barrées. Nous avons comparé la position des rayons dynamiques avec les longueurs de barre déterminées selon plusieurs critères observationnels sur nos images simulées dans les bandes B et K. Nous montrons ainsi qu'il est possible d'estimer la position de la résonance ultra-harmonique et de la corotation par une analyse attentive de la distribution de brillance de surface des galaxies barrées.

Download or read book All in the Downs written by Shirley Collins and published by MIT Press. This book was released on 2018-06-26 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: A memoir from one of Britain's legendary singers, folklorists, and music historians. A legendary singer, folklorist, and music historian, Shirley Collins has been an integral part of the folk-music revival for more than sixty years. In her new memoir, All in the Downs, Collins tells the story of that lifelong relationship with English folksong—a dedication to artistic integrity that has guided her through the triumphs and tragedies of her life. All in the Downs combines elements of memoir—from her working-class origins in wartime Hastings to the bright lights of the 1950s folk revival in London—alongside reflections on the role traditional music and the English landscape have played in shaping her vision. From formative field recordings made with Alan Lomax in the United States to the “crowning glories” recorded with her sister Dolly on the Sussex Downs, she writes of the obstacles that led to her withdrawal from the spotlight and the redemption of a new artistic flourishing that continues today with her unexpected return to recording in 2016. Through it all, Shirley Collins has been guided and supported by three vital and inseparable loves: traditional English song, the people and landscape of her native Sussex, and an unwavering sense of artistic integrity. All in the Downs pays tribute to these passions, and in doing so, illustrates a way of life as old as England, that has all but vanished from this land. Generously illustrated with rare archival material.

Download or read book Cartographic Humanism written by Katharina N. Piechocki and published by University of Chicago Press. This book was released on 2021-09-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Piechocki calls for an examination of the idea of Europe as a geographical concept, tracing its development in the 15th and 16th centuries. What is “Europe,” and when did it come to be? In the Renaissance, the term “Europe” circulated widely. But as Katharina N. Piechocki argues in this compelling book, the continent itself was only in the making in the fifteenth and sixteenth centuries. Cartographic Humanism sheds new light on how humanists negotiated and defined Europe’s boundaries at a momentous shift in the continent’s formation: when a new imagining of Europe was driven by the rise of cartography. As Piechocki shows, this tool of geography, philosophy, and philology was used not only to represent but, more importantly, also to shape and promote an image of Europe quite unparalleled in previous centuries. Engaging with poets, historians, and mapmakers, Piechocki resists an easy categorization of the continent, scrutinizing Europe as an unexamined category that demands a much more careful and nuanced investigation than scholars of early modernity have hitherto undertaken. Unprecedented in its geographic scope, Cartographic Humanism is the first book to chart new itineraries across Europe as it brings France, Germany, Italy, Poland, and Portugal into a lively, interdisciplinary dialogue.
Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Download or read book Theory of Accretion Disks written by F. Meyer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of space observatories and modern developments in ground based astronomy and concurrent progress in the theoretical understanding of these observations it has become clear that accretion of material on to compact objects is an ubiquitous mechanism powering very diverse astrophysical sources ranging in size and luminosity by many orders of magnitude. A problem common to these systems is that the material accreted must in general get rid of its angular momentum and this leads to the formation of an Accretion Disk which allows angular momentum re-distribution and converts potential energy into radiation with an efficiency which can be higher than the nuclear burning yield. These systems range in size from quasars and active galactic nuclei to accretion disks around forming stars and the early solar system and to compact binaries such as cataclysmic variables and low-mass X-ray binaries. Other objects that should be mentioned in this context are 88433, the black hole binary candidates, and possibly gamma-ray burst sources. Observations of these systems have provided important constraints for theoretical accretion disk models on widely differing scales, lumi nosities, mass-transfer rates and physical environments.

Book excerpt: One of the rising stars in the international art scene, Kader Attia (b. 1970) is a French-Algerian multidisciplinary artist whose powerful yet complex images, objects and installations examine the way cultures and histories have been constructed.Attia often plays with the vocabulary of museums and architecture to trouble the boundaries between different worlds, particularly Western and non-Western, through his use of re-appropriated and repaired everyday objects and ephemera, such as African masks, stapled paving cracks, assemblages of prostheses and photographs of surgical reconstruction.An in-depth interview with Hayward Gallery director Ralph Rugoff explores the artist's major themes, while art historians and other experts draw out particular threads to examine in depth. Compact but wide-ranging, this is a publication to be held in the hand - an indispensable first guide to an artist with an exceptional perspective on the way humans think about their place in the world.The book features an interview with Ralph Rugoff and essays by Nicola Clayton, Jean-Michel Frodon, Francoise Vergès and Giovanna Zapperi.Published alongside Hayward Gallery's exhibition, London (12 February - 6 May 2019).
Download or read book Autumn in Peking written by Boris Vian and published by Tamtam Books. This book was released on 2005 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiction. Translated from the French by Paul Knobloch. Originally published in 1947. "In the Exopotamian desert, where hepatrols blossom and children collect little animals called sandpeepers, the sun shines in an unusual way: it produces eerie black zones whose mysteries remain unexplained. Above all, Vian's pecurilar way with language proves that, indeed, life in the desert is equal to none. Since unusual language is bound to produce unusual fiction, it follows that the story does not take place in the fall, nor is it set in China" - from the Foreword by Marc Lapprand. The fourth novel by Vian, who was a contemporary of Sartre and Beauvoir. His innovative style, cutting-edge during his lifetime, but only successful in the sixties, made him an icon of the May 1968 student movement.
