Beam-Foil Spectroscopy

Beam-Foil Spectroscopy

Autor: Ivan Sellin

Número de Páginas: 461

The appreciable evolution of the nearly teenaged branch of atomic and molecular physics called beam foil spectroscopy is clearly depicted in the present volumes, which are devoted to publication of presentations at the Fourth International Conference on Beam Foil Spectroscopy and Heavy Ion Atomic Physics Symposium. The transition from childhood to adolescence parallels human experience in that diffusion of interests and interactions beyond the confines of the original family has most certainly occurred. The pre-occupation with techniques and their develop ment has been largely replaced by interest in the physics of the widest possible array of atomic and molecular physics experiments, in which spectroscopic study (visible, UV, XUV, X-ray, electron) of collisional interactions of fast beams is the unifying theme. The description "accelerator-based atomic physics" is perhaps more representative of the subject today than is the original, beam-foil spectroscopy," since so many experiments have nothing to do with foils, and furthermore, employ spectroscopy mainly as an incidental tool. What, then distinguishes beam-foil spectro scopy from overlapping fields of atomic collisions...

Soft X-Ray Emission from Clusters of Galaxies and Related Phenomena

Soft X-Ray Emission from Clusters of Galaxies and Related Phenomena

Autor: R. Lieu , Jonathan Mittaz

Número de Páginas: 198

Since the discovery of the cluster soft excess (CSE) over eight years ago, its properties and origin have been the subject of debate. With the recent launch of new missions such as XMM-Newton and FUSE, we are beginning to answer some of the complex issues regarding the phenomenon. This conference proceedings is an attempt to bring together the latest research results and covers both observational and theoretical work on the CSE and related topics. One of the main topics is the possible relationship between the CSE and the warm-hot intergalactic medium (WHIM), which is believed to harbor 50% of the baryons in the near Universe. New data from both XMM-Newton and FUSE have indicated a possible causal link between the WHIM and CSE. Evidence is based on the apparent detection of O VII emission lines in the soft excess spectrum of the outskirts of several clusters, as well as reports of absorption lines at local and higher redshifts (seen in the spectra of distant sources) as signature of the WHIM. However, while there has been considerable optimism in attributing a substantial fraction of the cluster soft excess flux to WHIM emission, other work shows that, for example, the amount of...

Supermassive Black Holes in the Distant Universe

Supermassive Black Holes in the Distant Universe

Autor: A.j. Barger

Número de Páginas: 310

Quasars, and the menagerie of other galaxies with "unusual nuclei", now collectively known as Active Galactic Nuclei or AGN, have, in one form or another, sparked the interest of astronomers for over 60 years. The only known mechanism that can explain the staggering amounts of energy emitted by the innermost regions of these systems is gravitational energy release by matter falling towards a supermassive black hole --- a black hole whose mass is millions to billions of times the mass of our Sun. AGN emit radiation at all wavelengths. X-rays originating at a distance of a few times the event horizon of the black hole are the emissions closest to the black hole that we can detect; thus, X-rays directly reveal the presence of active supermassive black holes. Oftentimes, however, the supermassive black holes that lie at the centers of AGN are cocooned in gas and dust that absorb the emitted low energy X-rays and the optical and ultraviolet light, hiding the black hole from view at these wavelengths. Until recently, this low-energy absorption presented a major obstacle in observational efforts to map the accretion history of the universe. In 1999 and 2000, the launches of the Chandra...

Laser Interaction and Related Plasma Phenomena

Laser Interaction and Related Plasma Phenomena

Autor: Heinrich Hora

Número de Páginas: 573

Paul Harteck Rensselaer Polytechnic Institute Troy, New York When the Maser and the Laser Were discovered, people were speculating if this was the beginning of a new page, or even a new chapter, in the Book of Physics. The Second Workshop on "Laser Interaction and Related Plasma Phenomena" held in Hartford made it clear that the perspective had changed, that people now question if the consequences of these discoveries constitute a new chapter, or possibly a new era in Physics. While the papers presented were all stimulating and of out standing quality, of special interest were the experiments which demonstrated that triggering of thermonuclear fusion by Laser techniques is indeed in the realm of the possible. Along these lines, I enjoy recalling an anecdote concerning the late F. G. Houtermans. I think that all who knew him will agree that he was an unusual genius and at the same time a very amusing colleague.

Introduction to Plasma Spectroscopy

Introduction to Plasma Spectroscopy

Autor: Hans-joachim Kunze

Número de Páginas: 250

Although based on lectures given for graduate students and postgraduates starting in plasma physics, this concise introduction to the fundamental processes and tools is as well directed at established researchers who are newcomers to spectroscopy and seek quick access to the diagnostics of plasmas ranging from low- to high-density technical systems at low temperatures, as well as from low- to high-density hot plasmas. Basic ideas and fundamental concepts are introduced as well as typical instrumentation from the X-ray to the infrared spectral regions. Examples, techniques and methods illustrate the possibilities. This book directly addresses the experimentalist who actually has to carry out the experiments and their interpretation. For that reason about half of the book is devoted to experimental problems, the instrumentation, components, detectors and calibration.

Heating in Toroidal Plasmas 1978

Heating in Toroidal Plasmas 1978

Autor: T. Consoli

Número de Páginas: 752

Heating in Toroidal Plasmas 1978, Volume 1 contains the proceedings of the 2nd Joint Grenoble-Varenna International Symposium held in Grenoble, France, on July 3-7, 1978. The symposium provided a forum for reviewing the status of heating of toroidal plasmas as a means of creating a practically inexhaustible source of energy with maximum safety and economy. Topics covered range from nuclear beam injection to heating at ion cyclotron- and lower frequencies, as well as lower hybrid resonance heating and electron cyclotron heating. Comprised of 52 chapters, this volume first looks at the implications of Theoretical scaling laws, followed by a detailed account on the use of duality and complex vectorial space for the orthonormal decomposition of the electromagnetic field in anisotropic media. The reader is then introduced to the topology of Tokamak orbits; behavior of fast ions in a large Tokamak plasma during nuclear beam injection heating; and heating of a toroidal plasma by skin current. Subsequent chapters focus on parametric instabilities in weakly-inhomogeneous hot plasmas; wave trajectory and electron cyclotron heating in toroidal plasmas; considerations on the design of a...

Italy and the Classical Tradition

Italy and the Classical Tradition

Autor: Bloomsbury Publishing

Número de Páginas: 280

Italy's original fascination with its cultural origins in Greece and Rome first created what is now known as 'the Classical tradition' - the pervasive influence of ancient art and thought on later times. In response to a growing interest in Classical reception, this volume provides a timely reappraisal of the Greek and Roman legacies in Italian literary history. There are fresh insights on the early study of Greek and Latin texts in post-classical Italy and reassessments of the significance attached to ancient authors and ideas in the Renaissance, as well as some innovative interpretations of canonical Italian authors, including Dante, Petrarch and Alberti, in the light of their ancient influences and models. The wide range of essays in this volume - all by leading specialists - should appeal to anyone with an interest in Italian literature or the Classical tradition. Italy's early fascination with its Hellenic and Roman origins created what is now called 'the classical tradition'.This book focuses on the role of the Greek and Latin languages and texts in Italian humanist thought and Renaissance poetry: how ancient languages were mastered and used, and how ancient texts were...

Scientific Drivers for ESO Future VLT/VLTI Instrumentation

Autor: J. Bergeron , G. Monnet

Número de Páginas: 367

This is the start of a long process to ultimately operate new advanced capabilities at Paranal that can keep up with the evergrowing need for larger and more complex astrophysical data sets. A modern instrument represents a very significant investment in cash, human resources and time. Such a meeting gives us a precious yardstick to evaluate the competitiveness of 1st-generation instruments and associated current and forthcoming proposals for 1st-generation upgrades. This is also crucial to orient the large research and development effort that will provide the very foundation on which 2nd-generation VLT instrumentation can be built. Finally, it represents a significant step towards defining the hopes and goals for the future Extremely Large Telescope to come. The first outcome of this meeting, already in progress, is outlined in the epilogue.

Nonequilibrium Statistical Mechanics of Heterogeneous Fluid Systems

Nonequilibrium Statistical Mechanics of Heterogeneous Fluid Systems

Autor: Andrei G. Bashkirov

Número de Páginas: 180

There is a wide variety of heterogeneous fluid systems that possess interphase surfaces. This monograph is devoted to pioneering studies in nonequilibrium statistical mechanics of such systems. Starting from the Liouville equation, the equations of surface hydrodynamics are derived with allowance for discontinuities of thermodynamic parameters of interphase boundaries. Brownian motion of a large solid particle in a fluid and nucleation are treated as results of fluctuations of flows across particle surfaces. With the use of the Gibbs method, a shock wave in a gas is considered as a sort of an interphase surface, and the surface tension of a shock front is introduced for the first time.

The Magnetodiscs and Aurorae of Giant Planets

The Magnetodiscs and Aurorae of Giant Planets

Autor: Karoly Szego , Nicholas Achilleos , Chris Arridge , Sarah Badman , Peter Delamere , Denis Grodent , Margaret Galland Kivelson , Philippe Louarn

Número de Páginas: 332

Readers will find grouped together here the most recent observations, current theoretical models and present understanding of the coupled atmosphere, magnetosphere and solar wind system. The book begins with a general discussion of mass, energy and momentum transport in magnetodiscs. The physics of partially ionized plasmas of the giant planet magnetodiscs is of general interest throughout the field of space physics, heliophysics and astrophysical plasmas; therefore, understanding the basic physical processes associated with magnetodiscs has universal applications. The second chapter characterizes the solar wind interaction and auroral responses to solar wind driven dynamics. The third chapter describes the role of magnetic reconnection and the effects on plasma transport. Finally, the last chapter characterizes the spectral and spatial properties of auroral emissions, distinguishing between solar wind drivers and internal driving mechanisms. The in-depth reviews provide an excellent reference for future research in this discipline.

The Languages and Linguistics of the New Guinea Area

The Languages and Linguistics of the New Guinea Area

Autor: Bill Palmer

Número de Páginas: 1036

The Languages and Linguistics of the New Guinea Area: A Comprehensive Guide is part of the multi-volume reference work on the languages and linguistics of all major regions of the world. The island of New Guinea and its offshore islands is arguably the most diverse and least documented linguistic hotspot in the world - home to over 1300 languages, almost one fifth of all living languages, in more than 40 separate families, along with numerous isolates. Traditionally one of the least understood linguistic regions, ongoing research allows for the first time a comprehensive guide. Given the vastness of the region and limited previous overviews, this volume focuses on an account of the families and major languages of each area within the region, including brief grammatical descriptions of many of the languages. The volume also includes a typological overview of Papuan languages, and a chapter on Austronesian-Papuan contact. It will make accessible current knowledge on this complex region, and will be the standard reference on the region. It is aimed at typologists, endangered language specialists, graduate and advanced undergraduate students, and all those interested in linguistic...

QSO Absorption Lines

QSO Absorption Lines

Autor: Georges Meylan

Número de Páginas: 481

The controversial question of whether the majority of the narrow absorption lines observed in QSO spectra represent cosmological intervening systems or ejecta from the QSO themselves is settled. QSO absorption line spectroscopy, initially a mere technique, has matured into an essential extragalactic research tool for understanding the content of the Universe at redshifts between 0 and 4, and beyond. The only previous important meeting devoted to "QSO Absorption Lines" was held in May 1987 at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A. Since that time, nearly a decade ago, research has been ex tremely active in this now well-established field of astrophysics. Theoretical stud ies and simulations have taken advantage of the constant progress in computer technology, and during these last few years, the observational results have bene fited largely from the new facillities offered by the Hubble Space Telescope in the UV wavelength range and the Keck Telescope for high-resolution spectroscopy.

Fifty Years of Quasars

Fifty Years of Quasars

Autor: Mauro D'onofrio , Paola Marziani , Jack W. Sulentic

Número de Páginas: 613

The 50th anniversary of the discovery of quasars in 1963 presents an interesting opportunity to ask questions about the current state of quasar research. Formatted as a series of interviews with noted researchers in the field, each of them asked to address a specific set of questions covering topics selected by the editors, this book deals with the historical development of quasar research and discusses how advances in instrumentation and computational capabilities have benefitted quasar astronomy and have changed our basic understanding of quasars. In the last part of the book the interviews address the current topic of the role of quasars in galaxy evolution. They summarise open issues in understanding active galactic nuclei and quasars and present an outlook regarding what future observational facilities both on the ground and in space might reveal. Its interview format, the fascinating topic of quasars and black holes, and the lively recollections and at times controversial views of the contributors make this book both rewarding and a pleasure to read!
