TheinternationalconferenceHowdoestheGalaxywork? Agalactictertulia rd th with Don Cox and Ron Reynolds, was held during the week of 23 to 27 of June 2003 in the marvelous city of Granada, Spain. This week marked the beginningofoneofthehottestsummersthatwehaveeverlived, butincontrast, the meeting was one of the coolest events that we can remember! First, it certainly wasa?rstclassscienti?creunion, withanexcellent program, talented speakers, and alive discussions in a friendly atmosphere. Second, the whole event was embedded in the passionate Andalucian way of life, a true tertulia, well seasoned with tasty tapas and perfectly marinated in cool and dry sherry wine. Third, the celebration was framed by some of the most beautiful settings thatonecanimagine; weenjoyedthemagni?centsplendoroftheAlhambra,the unique Muslim-Jewish-Christian ?avor of the Albaicin, and the magical gipsy heartbeat of Sacromonte. Last but not least, all discussions, whether they were duringthesessionsoratabartable,weresprinkledwiththecharmandwitofthe twoguestsofhonor: DonCoxandRonReynolds. Theideaofhavingascienti?c feast to celebrate their 60th birthday in Granada was actually conceived at a bar table in Seville, with plenty of manzanilla at hand, a couple of summers ago. That, perhaps, was the dif?cult part of the project. The rest was relatively easy to achieve because Don and Ron are not only remarkable astronomers but they are also great human beings. Indeed, we had a very positive response from all parties involved: every person we talked to was enthusiastic about the celebration, and wanted to give their own point of view in this tertulia.

This volume provides a thorough discussion of the evolution of elemental abundances in the Galaxy taking into account both spatial and temporal variations. For the first time, and in much greater detail, the observed chemical abundances are interpreted in terms of formation and evolution of the Galaxy. Observational constraints like the gas and star formation rate distribution are guiding this interpretation. Readers will find this monograph to be a unique research tool for expert scientists, graduate students, and everyone else who wants to get a deeper understanding of the chemical evolution of the Milky Way and galaxies in general.

Over the last decade, statisticians have developed new statistical tools in the field of spatial point processes. At the same time, observational efforts have yielded a huge amount of new cosmological data to analyze. Although the main tools in astronomy for comparing theoretical results with observation are statistical, in recent years, cosmologists have not been generally aware of the developments in statistics and vice versa. Statistics of the Galaxy Distribution describes both the available observational data on the distribution of galaxies and the applications of spatial statistics in cosmology. It gives a detailed derivation of the statistical methods used to study the galaxy distribution and the cosmological physics needed to formulate the statistical models. Because the prevalent approach in cosmological statistics has been frequentist, the authors focus on the most widely used of these methods, but they also explore Bayesian techniques that have become popular in large-scale structure studies. Describing the most popular methods, their latest applications, and the necessary mathematical and astrophysical background, this groundbreaking book presents the state of the art in the statistical description of the large-scale structure of the Universe. Cosmology's well-defined and growing data sets represent an important challenge for the statistical analysis, and therefore for the statistics community. Statistics of the Galaxy Distribution presents a unique opportunity for researchers in both fields to strengthen the connection between them and, using a common language, explore the statistical description of the universe.

The Galaxy Disk In Cosmological Context Iau S254

The paradigm of a dark energy- and dark matter-dominated Universe, with the hierarchical merger scenario for the formation of galaxies, has scored impressive successes in matching the observed Universe. However, the theory fails to explain the difficulty in generating ordinary disk galaxies such as the Milky Way, suggesting that some important physics must be missing in current models. IAU Symposium 254 was organized to address this question, gathering researchers from an unusually broad range of fields, from cosmology to interstellar matter, and the formation and evolution of stars. High-class reviews, lectures and posters combine to define the frontiers in the field and point the way to new avenues of research. This volume presents a unique set of succinct overviews illuminating the full range of topics in this very active field. It also honours Danish astrophysicist Bengt Strömgren (1908–1987), who laid much of the foundation for this entire field.

High Energy Astrophysics Volume 2 Stars The Galaxy And The Interstellar Medium

What role does viscosity play in accretion discs? How do you calculate the 'glitch function' of a pulsar? And can strong shocks account for the energy spectrum of electrons in our Galaxy? These are just some of the exciting questions that Professor Longair uses to develop the physics needed by the astronomer and high energy astrophysicist. The highly acclaimed first edition of High Energy Astrophysics instantly established itself as a classic in the teaching of contemporary astronomy. Reflecting the immense interest and developments in the subject, Professor Longair has developed the second edition into three texts; in this second volume he provides a comprehensive discussion of the high energy astrophysics of stars, the Galaxy and the interstellar medium. He develops an understanding for the essential physics with an elegance and infectious enthusiasm for which his teaching is internationally renowned, illustrating the issues throughout with results from forefront research. This book takes the student with a knowledge of physics and mathematics at the undergraduate level - but not necessarily with training in astronomy - to the point where current astronomical research can be understood.
