In the context of the NASA Deep Impact space mission, comet 9P/Tempel1 has been at the focus of an unprecedented worldwide long-term multi-wavelength observation campaign. The comet was also studied throughout its perihelion passage by various sources including the Deep Impact mission itself, the Hubble Space Telescope, Spitzer, Rosetta, XMM and all major ground-based observatories in a wavelength band from cm-wave radio astronomy to x-rays. This book includes the proceedings of a meeting that brought together an audience of theoreticians and observers - across the electromagnetic spectrum and from different sites and projects - to make full use of the massive ground-based observing data set. The coherent presentation of all data sets illustrates and examines the various observational constraints on modelling the cometary nucleus, cometary gas, cometary plasma, cometary dust, and the comet's surface and its activity.

Translated from the original French and annotated with figures, historical maps and commentary from the translators, this work is Jean-Charles Houzeau's account of his escape from Texas during the American Civil War.

What makes one author a good communicator and another a poor one? How to communicate scientific results through adequate and efficient scientific writing? How does the editorial process of a journal function, and why do scientific papers need to be refereed? All these questions, and many more, were the drivers for organizing in 2008 and in 2009 the three-day "Scientific Writing for Young Astronomers" courses for beginning PhD Students. This book copes with the preparation of manuscripts, with communicating with editors and referees, and with avoiding common errors in scientific writing. An entire chapter is devoted to communication with graphics, i.e., to various facets of visual communication by way of images, graphs, diagrams and tabular material. Special attention is given to the verity of graphical content, and to misrepresentations and errors in graphics and associated basic statistics. The central theme throughout this book is truthful communication of scientific results, involving the ethical principles of proper conduct in research and in scientific writing. Although the SWYA project was conceived for young astronomers, this Volume is far more than just a book for young astronomy students: it addresses many general issues related to technical, scientific, and social aspects of scientific writing, and is meant for a much wider audience. This includes graduate and seasoned students, as well as postdoctoral fellows and thesis supervisors in almost any discipline of the exact sciences. As the underlying theme is that verity and truth are the core business of science, it makes this book also of interest to scientometrists and science administrators.

What makes one scientist a good communicator and another a poor one? How communicate scientific results through adequate and efficient scientific writing? How does the editorial process of a journal function, and why do scientific papers need to be refereed? All these questions, and many more, led the Board of Directors of the leading professional journal Astronomy & Astrophysics (A&A) and its publisher EDP Sciences to organize, under the direction of Christiaan Sterken, the Scientific Writing for Young Astronomers courses for beginning PhD Students. This book contains a set of seven lectures that were delivered during two schools that took place in 2008 and 2009 in Blankenberge, Belgium. The contributions discuss all aspects of scientific publication, from the history and operations of A&A, its Editors' views of the peerreview and publishing processes, and the publication process as seen from the Publisher's side. Two chapters written by the A&A language editors deal with the principles of effective scientific writing. The last two contributions focus on the use of library services and large database facilities in the context of astronomical research and publication.
