Book Description
"This volume contains the proceedings of an international conference held in October 2006 in Sintra, Portugal, on the recent results from the deepest astronomical observations of the Universe. Focused on the latest observational developments in galaxy and structure formation and evolution, as given by the use of the most powerful telescopes working throughout the electromagnetic spectrum, the conference assembled some of the most active researchers in the field. The ninety-eight contributions included in this volume represent the state-of-the-art of research covering such topics as: the first billion years of galaxy formation, probing the reionization epoch, obscured galaxy populations and their role in galaxy evolution, early AGN activity, the star formation and mass assembly history of the Universe, massive galaxies at high-redshift and the metallicity history of galaxies. A particular emphasis is given to the unification of the different views given by observations at different wavelengths, making the books a valuable reference for researchers and graduate students interested in the exploration of the distant universe." -- publisher's website.

Book Description
The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth â€" SM-4 â€" was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble's useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble's productive life.

Book Description
"These proceedings are an overview of the status of the Hinode mission a year after launch with particular emphasis on instrument performance and the scientific results from the first data release. Hinode was designed to study the sun at high spatial and temporal resolution in order to answer the fundamental questions on how its magnetic fields are formed and evolve, and how their interaction with the solar plasma creates the wide variety of active phenomena that are observed on the sun. The papers presented at the conference and published in this volume contain a number of new and significant advances in this area. The conference covered a broad range of topics that included the most pressing open questions in solar physics, such as the emergence and evolution of magnetic fields, their impact on structuring and heating the solar atmosphere, the origins of the solar wind, and explosive energy release on all scales. This book therefor provides a broad picture of the current advances in observational solar physics made by Hinode, raising a number of new questions in several areas. It is suitable for researchers and graduate students interested in solar and stellar physics and in the processes involved in magnetized plasma environments in general."--Publisher's website

Book Description
A symposium to celebrate the life of Bohdan Paczynski (1940-2007), Lyman Spitzer Jr. Professor of Theoretical Astrophysics at Princeton University, took place on 29-30 September 2007. Bohdan Paczynski impacted astronomy and astronomers alike with his innovative ideas, philosophies, and insight to astronomy, science and life in general. This volume has assembled thoughts, memories and scientific accomplishments influenced in one way or another by Bohdan, who was a Giant in his field. Nine friends, colleagues and admirers who have been touched by Paczynski personally, professionally, or both, contributed invited presentations. Topics in this volume include the influence of Bohdan Paczynski in the field of stellar evolution and variable stars, his crucial role in making the Optical Gravitational Lensing Experiment (OGLE) and the All Sky Automated Survey (ASAS) possible, and his revolutionary insistence on allowing anyone and everyone access to his stellar evolution code: The Paczynski Code. Also included are Bohdan's contributions to gravitational microlensing and the search for dark matter in the form of MACHOs. Particular emphasis is given to advances and unexpected discoveries from surveys such as MACHO, OGLE, and EROS. The impact Paczynski had on our understanding of gamma-ray bursts is also discussed. Finally, this celebration of Professor Bohdan Paczynski is completed with the addition of personal accounts of his life, brilliance, sense of humor, and inspiration to others. Paczynski's scientific contributions reach across all of astrophysics and bridge the gap between observation and theory. This book is of interest not only to those who knew him, but also to those who know of him and the immeasurable ways he left his mark on the community.

Book Description
These are the proceedings of "Cosmology Across Cultures: An International Conference on the Impact of the Study of the Universe in Human Thinking" organized by the Spanish Institutes of Astrophysics of the Canaries and Andalucía under the patronage of the European Society for Astronomy in Culture (SEAC). The conference hosted in the multicultural historical city of Granada more than 80 participants from all the continents. This conference joined specialists of cultural astronomy studies and modern cosmology in a single forum where ideas about the comprehension of the Universe across time, space, and cultures were interchanged, analyzed, revised, and challenged. An experiment, excellently represented by this book, it worked out in a most satisfactory ambience, permitting both modern cosmologists to receive an insight of how people in the past perceived the cosmos and cultural astronomers to understand the great advances of cosmology in the last few decades and consequently the exact and modest position occupied by humankind in an expanding universe dominated by dark matter and dark energy. The volume is chronologically organized, beginning with modern cosmological studies, followed by historical documentation, and ending with information from archaeological remains. Each section of the book can be studied independently, although a general inspection of the complete volume is recommended to get a correct insight of the spirit of the conference. This book is of interest to any scholar or student wishing to understand the evolution of the human comprehension of the universe.

Book Description
"In the spring of 2006 a four day international workshop was held in Lunteren, The Netherlands, in honor of the formal retirement of Prof. Henny Lamers. These proceedings provide a comprehensive overview of mass loss in massive stars and of the dynamical fate of clusters. The dynamical evolution of clusters is affected by stellar winds, mass loss outbursts and supernova explosions as well as by the loss of stars in dynamical interactions, thus linking the two central themes of the workshop. It is becoming clear that mass loss by radiation pressure on spectral lines is not only at work in normal O, B, and A stars but also in Luminous Blue Variables and Wolf-Rayet stars. The importance of these line-driven winds relative to outbursts in the Luminous Blue Variable phase of evolution is under debate. A central issue in this discussion is the importance of small and possibly large scale structure in stellar winds and its implications for the measured mass loss rates. These proceedings report on progress establishing wind properties, on theoretical predictions of mass loss and wind structure as a function of stellar properties, and on the effects of mass loss on the evolution of massive stars. As a result of dynamical interactions, clusters may dissolve completely over time. Observational studies of cluster dissolution timescales as a function of cluster formation history and cluster and environmental properties, are at the focus of cluster studies in the last decade. A key topic discussed in this book is whether the old globular clusters we observe today were once similar to present-day massive young clusters. The mass function of the two types of clusters is observed to be different. Is this a result of dynamical evoltuion or were the mass functions different at formation? The 12 invited reviews, 18 contributed talks, 48 poster papers, and two discussion sessions combine to provide and in-depth assessment of both observational and theoretical issues. The book is suitable for researchers and graduate students interested in stellar astrophysics and cluster dynamics."--Provided by publisher.

Book Description
"In celebration of its 50th anniversary, the NRAO hosted a science symposium highlighting the most important questions that can be addressed by astronomers. The universe is a unique laboratory yielding historical data on the creation of the universe, the formation of the first stars and galaxies, the production of the elements, the assembly of molecules and the building blocks of life in interstellar space, how and where planets form, and possible changes in fundamental physical constants on cosmological time scales. This "laboratory" contains black holes, neutron stars, and gravitational radiation for studying extreme gravity and extremely dense matter. It is filled with the mysterious dark energy and dark matter that control the expansion and destiny of the universe, and whose nature is a critical unsolved problem for physics. This symposium brought together leading scientists to address the most important questions in these areas, the major contributions to astronomy enabled by NRAO instruments-past, present, and future - and to suggest future directions for research involving radio observations and techniques."--BOOK JACKET.
