It Was a Dark Time for the Galaxy In the late 1980s, Star Wars was becoming a fading memory. The movie trilogy had concluded. The comic books and novels were winding down. The action figures had run their course. As the franchise celebrated its tenth anniversary, there was a new ride at Disneyland and ... not much else. Not until a small hobby game company released Star Wars: The Roleplaying Game and The Star Wars Sourcebook. And suddenly the galaxy began to expand.This is the story of how a group of dedicated fans and gaming professionals helped pave the way for the Star Wars Expanded Universe - as told by one of the original architects! This book explains how material created for roleplaying games helped shape the Star Wars universe - and continues to influence it to the current day.

NAMED ONE OF THE BEST BOOKS OF THE YEAR BY NPR • A gripping science fiction saga about three students from a school for those with extraordinary powers, from the award-winning author of The Best of All Possible Worlds “A smart science fictional fable as inventive and involving as it is finally vital.”—Tordotcom On the verge of adulthood, Rafi attends the Lyceum, a school for the psionically gifted. Rafi possesses mental abilities that might benefit people . . . or control them. Some wish to help Rafi wield his powers responsibly; others see him as a threat to be contained. Rafi’s only freedom at the Lyceum is Wallrunning: a game of speed and agility played on vast vertical surfaces riddled with variable gravity fields. Serendipity and Ntenman are also students at the Lyceum, but unlike Rafi, they come from communities where such abilities are valued. Serendipity finds the Lyceum as much a prison as a school, and she yearns for a meaningful life beyond its gates. Ntenman, with his quick tongue, quicker mind, and a willingness to bend if not break the rules, has no problem fitting in. But he too has his reasons for wanting to escape. Now the three friends are about to experience a moment of violent change as seething tensions between rival star-faring civilizations come to a head. For Serendipity, this change will challenge her ideas of community and self. For Ntenman, it will open new opportunities and new dangers. And for Rafi, given a chance to train with some of the best Wallrunners in the galaxy, it will lead to the discovery that there is more to Wallrunning than he ever suspected . . . and more to himself than he ever dreamed. Includes two bonus short stories “There is a weight and grace to [Lord’s] prose that put me in mind of pewter jewelry.”—NPR “This novel is a satisfying exercise in being off-balance, a visceral lesson in how to fall forward and catch yourself in an amazing new place.”—The Seattle Times

This volume contains the written versions of the lectures given at the 26th course of the renowned Saas-Fee series. The book represents a comprehensive and up-to-date review of the field of galaxy interaction. Nowadays, galaxies are no longer seen as immutable objects: they evolve, interact, merge, blaze, and reshape. Dynamic forces can induce powerful stellar activity able to transform the matter composition and morphology of galaxies. The lectures included in this book aim at a better understanding of these remarkable and fascinating phenomena. Though the book is intended for graduate students and young post-docs in astrophysics, it contains more advanced and original material, as well as historical perspectives, which will be of great interest to experts and astronomy teachers also.

Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is still unclear, they stop forming stars and quietly end in the red sequence, as spheroids. This transformation may be due to galaxy interactions, or because of the feedback of active nuclei, through the energy released by their central super-massive black holes. These mechanisms could explain the history of cosmic star formation, the rate of which was far greater in the first half of the UniverseÂs life. Galaxies delves into all of these surrounding subjects in six chapters written by dedicated, specialist astronomers and researchers in the field, from their numerical simulations to their evolutions.

For every galaxy in the field or in clusters, there are about three galaxies in groups. The Milky Way itself resides in a group. Groups in the local universe offer the chance to study galaxies in environments characterized by strong interactions. In the cosmological context, groups trace large-scale structures better than clusters; the evolution of groups and clusters appears to be related. All these aspects of research are summarized in this book.
