Book Description
This volume is written by leading scientists in the field, who review the current state of our knowledge of tidal streams in the Milky Way, the Andromeda galaxy, and in other nearby galaxies. The cosmological origins of dwarf galaxies and the physical processes by which they are tidally disrupted into streams and incorporated into galaxy halos are discussed. The techniques that have been used to identify tidal streams are presented and will be useful to researchers who would like to find substructures in the next generation of optical sky surveys, including Pan-STARRS and LSST. The methods that are currently under development to constrain both large scale distribution of dark matter in the Milky Way and the (small scale) lumpiness of the dark matter distribution are also explained. The authors also provide motivation for future spectroscopic surveys of Milky Way halo stars, which will aid both in the identification of tidal streams and the constraint of dark matter properties. This volume is aimed at graduate students who are beginning this field of research, but is also a resource for researchers who study tidal streams and related fields. In addition to presenting the physical processes by which tidal streams are created, it also reviews the current state of the observations and the progress towards utilizing these observations to constrain the distribution of dark matter in the Milky Way. The book will introduce anyone with a background in astrophysics to the field of tidal streams.

Book Description
Since the invention of the telescope 400 years ago, astronomers have rapidly discovered countless celestial objects. But how does one make sense of it all? Astronomer and former NASA Chief Historian Steven J. Dick brings order to this menagerie by defining 82 classes of astronomical objects, which he places in a beginner-friendly system known as "Astronomy’s Three Kingdoms.” Rather than concentrating on technicalities, this system focuses on the history of each object, the nature of its discovery, and our current knowledge about it. The ensuing book can therefore be read on at least two levels. On one level, it is an illustrated guide to various types of astronomical wonders. On another level, it is considerably more: the first comprehensive classification system to cover all celestial objects in a consistent manner. Accompanying each spread are spectacular historical and modern images. The result is a pedagogical tour-de-force, whereby readers can easily master astronomy’s three realms of planets, stars, and galaxies.

Book Description
This book consists of invited reviews written by world-renowned experts on the subject of the outskirts of galaxies, an upcoming field which has been understudied so far. These regions are faint and hard to observe, yet hide a tremendous amount of information on the origin and early evolution of galaxies. They thus allow astronomers to address some of the most topical problems, such as gaseous and satellite accretion, radial migration, and merging. The book is published in conjunction with the celebration of the end of the four-year DAGAL project, an EU-funded initial training network, and with a major international conference on the topic held in March 2016 in Toledo. It thus reflects not only the views of the experts, but also the scientific discussions and progress achieved during the project and the meeting. The reviews in the book describe the most modern observations of the outer regions of our own Galaxy, and of galaxies in the local and high-redshift Universe. They tackle disks, haloes, streams, and accretion as observed through deep imaging and spectroscopy, and guide the reader through the various formation and evolution scenarios for galaxies. The reviews focus on the major open questions in the field, and explore how they can be tackled in the future. This book provides a unique entry point into the field for graduate students and non-specialists, and serves as a reference work for researchers in this exciting new field.

Book Description
Astronomy is a scienti?c discipline that has developed a rapid and impressive growth in Spain. Thirty years ago, Spain occupied a purely anecdotal presence in the international context, but today it occupies the eighth position in the world in publication of astronomical articles, and, among other successes, owns and op- ates ninety per cent of the world’s largest optical telescope GTC (Gran Telescopio Canarias). The Eighth Scienti?c Meeting of the Spanish Astronomical Society (Sociedad Espanol ̃ a de Astronom ́ a, SEA), held in Santander in July 7–11 2008, whose p- ceedings are in your hands, clearly shows the enthusiasm, motivation and quality of the present Spanish astronomical community. The event brought together 322 participants, who represent almost 50% of Spanish professional astronomers. This percentage, together with the continuously increasing, with respect to previous SEA meetings, number of oral presentations and poster contributions (179 and 127 respectively), con?rms that the SEA conferences have become a point of reference to assess the interests and achievements of astrophysical research in Spain. The most important and current topics of modern Astrophysics were taken into accountat thepreliminarymeeting,aswell as the numberandqualityofparticipants and their contributions, to select the invited speakers and oral contributors. We took a week to enjoy the high quality contributions submitted by Spanish astronomers to the Scienti?c Organizing Committee. The selection was dif?cult. We wish to acknowledge the gentle advice and commitment of the SOC members.

Book Description
Increasing renewable energy development, both within the United States and abroad, has rekindled interest in the potential for marine and hydrokinetic (MHK) resources to contribute to electricity generation. These resources derive from ocean tides, waves, and currents; temperature gradients in the ocean; and free-flowing rivers and streams. One measure of the interest in the possible use of these resources for electricity generation is the increasing number of permits that have been filed with the Federal Energy Regulatory Commission (FERC). As of December 2012, FERC had issued 4 licenses and 84 preliminary permits, up from virtually zero a decade ago. However, most of these permits are for developments along the Mississippi River, and the actual benefit realized from all MHK resources is extremely small. The first U.S. commercial gridconnected project, a tidal project in Maine with a capacity of less than 1 megawatt (MW), is currently delivering a fraction of that power to the grid and is due to be fully installed in 2013. As part of its assessment of MHK resources, DOE asked the National Research Council (NRC) to provide detailed evaluations. In response, the NRC formed the Committee on Marine Hydrokinetic Energy Technology Assessment. As directed in its statement of task (SOT), the committee first developed an interim report, released in June 2011, which focused on the wave and tidal resource assessments (Appendix B). The current report contains the committee's evaluation of all five of the DOE resource categories as well as the committee's comments on the overall MHK resource assessment process. This summary focuses on the committee's overarching findings and conclusions regarding a conceptual framework for developing the resource assessments, the aggregation of results into a single number, and the consistency across and coordination between the individual resource assessments. Critiques of the individual resource assessment, further discussion of the practical MHK resource base, and overarching conclusions and recommendations are explained in An Evaluation of the U.S. Department of Energy's Marine and Hydrokinetic Resource Assessment.

Book Description
In Beyond the Blue Horizon, bestselling science historian Brian Fagan tackles his richest topic yet: the enduring mystery of the oceans, the planet's most forbidding terrain.This is not a tale of Columbus or Hudson, but of much earlier mariners. From the moment when ancient Polynesians first dared to sail beyond the horizon, Fagan vividly explains how our mastery of the oceans has changed history, even before history was written. Beyond the Blue Horizon delves into the very beginnings of humanity's long and intimate relationship with the sea. It willl enthrall readers who enjoyed Longitude, Simon Winchester's Atlantic, or in its scope and its insightful linking of technology and culture, Guns, Germs, and Steel. What drove humans to risk their lives on open water? How did early sailors unlock the secrets of winds, tides, and the stars they steered by? What were the earliest ocean crossings like? With compelling detail, Brian Fagan reveals how seafaring evolved so that the vast realms of the sea gods were transformed from barriers into highways that hummed with commerce. Indeed, for most of human history, oceans have been the most vital connectors of far-flung societies. From bamboo rafts in the Java Sea to the caravels of the Age of Discovery, from Easter Island to Crete, Brian Fagan crafts a captivating narrative of humanity's urge to seek out distant shores, of the daring men and women who did so, and of the mark they have left on civilization.

Book Description
A wealth of information on the wildlife, stories and history of the islands.For those wishing to visit in small boats or kayaks there are details of:? Landings? Camping? Drinking water? Tidal informationOileain is a detailed guide to almost every Irish offshore island. The guide is comprehensive, describing over 300 islands, big and small, far out to sea and close in by the shore, inhabited and uninhabited. Oileain tells it as it is, rock by rock, good and bad, pleasant and otherwise. It concentrates on landings and access generally, then adds information on camping, drinking water, tides, history, climbing, birds, whales, dolphins, legends or anything else of interest.Oileain will, I hope, appeal to all who go to sea in small boats, divers and yachtsmen as well as kayakers. The sheer level of detail contained in Oileain must surely throw new light on places they thought they knew well. It is not a book about kayaking. It so happens that a practical way of getting to islands is by kayak, and that is how the author gets about. Scuba divers and RIBs get in close too. Yachtsmen get about better than most, and they too enjoy exploring intensively from a dinghy. With the increasing availability of ferries, boatless people will also enjoy Oileain. Offshore islands are the last wilderness in Ireland. Hillwaking is now so popular that there are few untrampled mainland hills. Ninety per cent of offshore islands are uninhabited outside of the first fortnight in August, and eighty per cent even then. You won't meet many other people, if any at all, out beyond an Irish surf line. It is a time of change though, and holiday homes are very much the coming thing in some offshore areas. Sea going will never stop being a great adventure. Therefore, offshore islands are still the preserve of the very few. Now is a golden era for exploration.
