Book Description
A collection of eight short stories and novellas in the dark and turbulent world of Alastair Reynolds' Revelation Space universe.Centuries from now, solidarity stretches thin as humanity spreads past the solar system and to the nearest stars. Technology has produced powerful new tools-but lethal risk will always accompany great advancement.And without foresight, opposing groups may fracture multiple worlds. Between the Demarchists and the Conjoiners, the basic right to expand human intelligence-beyond its natural limits-has become a war-worthy cause. Only vast lighthugger starships bind these squabbling colonies together, manned by the panicky and paranoid Ultras. And the hyperpigs just try to keep their heads down.The rich get richer. And everyone tries not to think about the worrying number of extinct alien civilizations turning up on the outer reaches of settled space...because who's to say that humanity won't be next?

Book Description
In the third book of the legendary Revelation Space trilogy, the last remnants of humanity realize that forging an alliance with a greater and even more mysterious alien force may be their only chance for survival. The Inhibitors were designed to eliminate any life form reaching a certain level of intelligence -- and they've targeted Humanity. War veteran Clavain and a ragtag group of refugees have fled into hiding. Their leadership is faltering, and their situation is growing more desperate. But their little colony has just received an unexpected visitor: an avenging angel with the power to lead mankind to safety -- or draw down its darkest enemy. And as she leads them to an apparently insignificant moon light-years away, it begins to dawn on Clavain and his companions that to beat one enemy, it may be necessary to forge an alliance with something much worse . . . "Absolution Gap is a good as it gets, and should solidify Alastair Reynolds' reputation as one of the best hard SF writers in the field." -- SF Site

Book Description
Since it was first published in 1987, Galactic Dynamics has become the most widely used advanced textbook on the structure and dynamics of galaxies and one of the most cited references in astrophysics. Now, in this extensively revised and updated edition, James Binney and Scott Tremaine describe the dramatic recent advances in this subject, making Galactic Dynamics the most authoritative introduction to galactic astrophysics available to advanced undergraduate students, graduate students, and researchers. Every part of the book has been thoroughly overhauled, and many sections have been completely rewritten. Many new topics are covered, including N-body simulation methods, black holes in stellar systems, linear stability and response theory, and galaxy formation in the cosmological context. Binney and Tremaine, two of the world's leading astrophysicists, use the tools of theoretical physics to describe how galaxies and other stellar systems work, succinctly and lucidly explaining theoretical principles and their applications to observational phenomena. They provide readers with an understanding of stellar dynamics at the level needed to reach the frontiers of the subject. This new edition of the classic text is the definitive introduction to the field. ? A complete revision and update of one of the most cited references in astrophysics Provides a comprehensive description of the dynamical structure and evolution of galaxies and other stellar systems Serves as both a graduate textbook and a resource for researchers Includes 20 color illustrations, 205 figures, and more than 200 problems Covers the gravitational N-body problem, hierarchical galaxy formation, galaxy mergers, dark matter, spiral structure, numerical simulations, orbits and chaos, equilibrium and stability of stellar systems, evolution of binary stars and star clusters, and much more Companion volume to Galactic Astronomy, the definitive book on the phenomenology of galaxies and star clusters

Book Description
Alastair Reynolds pushes the boundaries of science fiction and “confirms his place among the leaders of the hard-science space-opera renaissance” (Publishers Weekly) in this novel in his Revelation Space universe. Late in the twenty-sixth century, the human race has advanced enough to accidentally trigger the Inhibitors—alien killing machines designed to detect intelligent life and destroy it. The only hope for humanity lies in the recovery of a secret cache of doomsday weapons—and a renegade named Clavain who is determined to find them. But other factions want the weapons for their own purposes—and the weapons themselves have another agenda altogether...

Book Description
How can we test if a supermassive black hole lies at the heart of every active galactic nucleus? What are LINERS, BL Lacs, N galaxies, broad-line radio galaxies and radio-quiet quasars and how do they compare? This timely textbook answers these questions in a clear, comprehensive and self-contained introduction to active galactic nuclei - for graduate students in astronomy and physics. The study of AGN is one of the most dynamic areas of contemporary astronomy, involving one fifth of all research astronomers. This textbook provides a systematic review of the observed properties of AGN across the entire electromagnetic spectrum, examines the underlying physics, and shows how the brightest AGN, quasars, can be used to probe the farthest reaches of the Universe. This book serves as both an entry point to the research literature and as a valuable reference for researchers in the field.

Book Description
Return to the dazzling world of Revelation Space with this British Science Fiction Award-winning space opera about a young man hell-bent on revenge on the surface of a twisted, disease-corrupted planet. The once-utopian Chasm City -- a domed human settlement on an otherwise inhospitable planet -- has been overrun by a virus known as the Melding Plague, capable of infecting any body, organic or computerized. Now, with the entire city corrupted -- from the people to the very buildings they inhabit -- only the most wretched sort of existence remains. For security operative Tanner Mirabel, it is the landscape of nightmares through which he searches for a lowlife postmortal killer. But the stakes are raised when his search brings him face to face with a centuries-old atrocity that history would rather forget. One of Locus and Science Fiction Chronicle's "Best SF Novels of the Year"
