The thrilling sequel to In the Orbit of Sirens THE WORLD OF KAMARIA WILL NEVER BE THE SAME. In the aftermath of the brutal slaying of a sacred auk'nai deity, Cade and Nella Castus are taken from their home and brought deep into the wilderness. They must make their way back to civilization, traversing dangerous landscapes as they are pursued relentlessly by their captor-a winged abomination. As Denton and Eliana search for their missing children, they uncover something that will change life on Kamaria forever.

Nightmarish machines have driven humanity into the depths of space. The survivors are forced to adapt to a planet filled with monsters.

As a result of significant research over the past 20 years, black holes are now linked to some of the most spectacular and exciting phenomena in the Universe, ranging in size from those that have the same mass as stars to the super-massive objects that lie at the heart of most galaxies, including our own Milky Way. This book first introduces the properties of simple isolated holes, then adds in complications like rotation, accretion, radiation, and magnetic fields, finally arriving at a basic understanding of how these immense engines work. Black Hole Astrophysics • reviews our current knowledge of cosmic black holes and how they generate the most powerful observed pheonomena in the Universe; • highlights the latest, most up-to-date theories and discoveries in this very active area of astrophysical research; • demonstrates why we believe that black holes are responsible for important phenomena such as quasars, microquasars and gammaray bursts; • explains to the reader the nature of the violent and spectacular outfl ows (winds and jets) generated by black hole accretion.

Thoroughly revised and expanded throughout, the new edition is a graduate-level text and reference book on gaseous nebulae, nova and supernova remnants. Much of the new data and new images are from the Hubble Space Telescope with two wholly new chapters being added along with other new features. The previous edition which was tried and tested for thirty years has now been succeeded by a revised, updated, larger edition, which will be valuable to anyone seriously interested in astrophysics.

Contests the 'establishment' view of quasars as the most distant objects in the universe.

A pictorial drama of the creation of Heaven and Earth based upon the awe-inspiring photo images from the Hubble and Spitzer space telescopes. Author, Paul Hutchins uncovers a grand drama on a universal scale that has been playing out since the invention of the telescope. He poses the question, is this grand drama merely in response to an ancient invitation recorded in the Book of Isaiah? It states in Isaiah 40:26, ""Look up into the heavens."" Who created all the stars? Through the use of his imagination and the invention of the telescope, man has discovered a once secret doorway to a world beyond imagination. He has now, in this age of cutting edge technology developed flying space telescopes in his quest to know, how did we get here? What he has found has astounded him. Hutchins farther poses the question; if it took over 400 years of man’s imagination from when the telescope was invented, and countless other inventions including the Hubble and Spitzer space telescopes, to merely take photo images of the universe, then who’s imagination is responsible for the reality those photo images represent? As we peer through this doorway to the heavens and look upon these heavenly cosmic bodies, we find ourselves awed by their grandeur. The pressing question becomes too large to ignore. Who is responsible for all these things? Could it be that we are now peering into the mind of a supreme architect with an imagination far beyond that of mere mortals? Could we be peering into the mind of imagination supreme? Could it be that we have been brought to this point in history unbeknownst to ourselves and given this technology by the one who extended that ancient invitation recorded by Isaiah 2700 years ago?

In Home Is Where the Wind Blows, Sir Fred Hoyle, one of this century's most eminent scientists and author of dozens of successful books, both fiction and nonfiction, offers a revealing and charming account of his life and work. Mathematician, physicist, astronomer, cosmologist - Sir Fred is perhaps best known, in scientific circles, for his brilliant explanation of the origin of the elements from hydrogen nuclei in stars (a process known as nucleosynthesis) and for developing (with Sir Hermann Bondi and Thomas Gold) the elegant but controversial steady-state theory of the Universe (which assumes the continuous creation of matter). In 1950, in the last of a series of radio lectures on astronomy that he delivered on the air for the BBC, Sir Fred coined the term "Big Bang" to characterize the competing expanding-Universe theory, which has since become the dominant paradigm. Ironically, the term has become a permanent addition to the language of cosmology. Sir Fred's name has become well known to the general public because of his unusual ability to describe the ideas of science in a simple and accessible way. In addition to his scientific work, he has written more than a dozen works of popular science (many of them widely translated) and more than a dozen works of science fiction (most of them in collaboration with his son, Geoffrey). In all his work, Sir Fred has shown himself to be ready and able to challenge established thinking. In the author's amusing and memorable account of his childhood in Home Is Where the Wind Blows, the reader will see how this came to be true. Possessed since infancy with a strong streak of independence, he was encouraged by his parents, throughout his schoolyears, to trust his own judgment and to think for himself.

The 50th anniversary of the discovery of quasars in 1963 presents an interesting opportunity to ask questions about the current state of quasar research. Formatted as a series of interviews with noted researchers in the field, each of them asked to address a specific set of questions covering topics selected by the editors, this book deals with the historical development of quasar research and discusses how advances in instrumentation and computational capabilities have benefitted quasar astronomy and have changed our basic understanding of quasars. In the last part of the book the interviews address the current topic of the role of quasars in galaxy evolution. They summarise open issues in understanding active galactic nuclei and quasars and present an outlook regarding what future observational facilities both on the ground and in space might reveal. Its interview format, the fascinating topic of quasars and black holes, and the lively recollections and at times controversial views of the contributors make this book both rewarding and a pleasure to read!

Gamma ray astronomy, the branch of high energy astrophysics that studies the sky in energetic ?-ray photons, is destined to play a crucial role in the exploration of nonthermal phenomena in the Universe in their most extreme and violent forms. The great potential of this discipline offers impressive coverage of many OC hot topicsOCO of modern astrophysics and cosmology, such as the origin of galactic and extragalactic cosmic rays, particle acceleration and radiation processes under extreme astrophysical conditions, and the search for dark matter."

This thesis describes the application of a Monte Carlo radiative transfer code to accretion disc winds in two types of systems spanning 9 orders of magnitude in mass and size. In both cases, the results provide important new insights. On small scales, the presence of disc winds in accreting white dwarf binary systems has long been inferred from the presence of ultraviolet absorption lines. Here, the thesis shows that the same winds can also produce optical emission lines and a recombination continuum. On large scales, the thesis constructs a simple model of disc winds in quasars that is capable of explaining both the observed absorption and emission signatures – a crucial advance that supports a disc-wind based unification scenario for quasars. Lastly, the thesis also includes a theoretical investigation into the equivalent width distribution of the emission lines in quasars, which reveals a major challenge to all unification scenarios.
