Geminga


Book Description

Imagine … a raven on the branch of a fruit tree speaks to you, complimenting you on the song you have just sung. You, Rodger Games, carpenter by day and guitar-player by night, are drawn by the wonder: the how, where, and why of its origins. A dialogue begins. But along with the mystery of the raven arrives the snake, a deadly ‘breath-of-heaven’, its assassin partner. The duo once worked for Shining Path, the Peruvian Maoist movement founded by the arch-ideologue, Zalo. Soon the trail leads to the Medellin Cartel and ‘The Center’ – a secret institute staffed by the tutored sons of Mengele and located in the remotest Amazon. Adjacent to the dialogue appear farm workers and laborers – Black, White, Indian, and Hispanic – a young woman of focal beauty named Luana, and a midnight prowler who drives a black Porsche; and always, the ubiquitous digressions of memory. Where will it lead? To what end? Consider: ravens, snakes, and revolutionaries, God, Devil, man, and woman all transformed into a pair of dice … roll ’em...whadaya get? The lucky seven? double-sixes? or snake-eyes? And with what consequence? The mystery is something of a creation myth. For eventually there is a harvest: the cruel scythe of political terrorism; the blessing of woman, fruit and song, and the promise of a mystical union, for with the harvest is planted the seed of new potential … Geminga.




Magic Universe


Book Description

This is a marvellously engaging tour covering the whole of modern science, from transgenic crops to quantum tangles. Written by one of the most experienced and well-known names in science writing, it is also assuredly reliable science. Although arranged for convenience and quick reference as a collection of topics in alphabetical order, it is very different from any conventional encyclopedia. Each topic tells a story, making the book eminently browsable. Packed with information, yet carrying its immense learning lightly, this is a book that would appeal to anyone with the slightest interest in how the world works.

Introducing the Stars


Book Description

This textbook introduces the reader to the basic concepts and equations that describe stellar structure. Various approximation techniques are used to solve equations, and an intuitive rather than rigorous approach is employed to interpret the properties of the stars. The book provides step-by-step instructions, helpful exercises and relevant historical lessons to familiarize students with key concepts and mathematical theories. Based upon a series of one-semester (12 weeks) elective undergraduate courses offered at the University of Regina, this book is intended for students who are interested in seeing how basic calculus and introductory physics can be applied to the understanding of the stars from their formation to their death. The text provides an intermediate stepping stone between lower-level undergraduate classes and more specialized postgraduate texts on the subject of stellar structure.




The Multi-Messenger Approach to High-Energy Gamma-Ray Sources


Book Description

This book provides a theoretical and observational overview of the state of the art of gamma-ray astrophysics, and their impact and connection with the physics of cosmic rays and neutrinos. With the aim of shedding new and fresh light on the problem of the nature of the gamma-ray sources, particularly those yet unidentified, this book summarizes contributions to a workshop that continues today.




The Lives of the Neutron Stars


Book Description

This NATO AS! was the third in the series of Advanced Study Institutes on neutron stars, which started with 'Timing Neutron Stars', held in Qe§me near izmir, Turkey (April 1988), followed by 'Neutron Stars, an Interdis ciplinary Subject', held in Agia Pelagia on the island of Crete (September 1990). The first school centered on our main observational access to neu tron stars, i. e. the timing of radio pulsars and accretion powered neutron stars, and on what timing of neutron stars teaches us of their structure and environment. The second school had as its theme the interplay between diverse areas of physics which find interesting, even exotic applications in the extreme conditions of neutron stars and their magnetospheres. As the field has developed, with the number of observed neutron stars rapidly in creasing, and our knowledge of many individual neutron stars getting deeper and more detailed, an evolutionary picture of neutron stars has started to emerge. This led us to choose 'The Lives of the Neutron Stars' as the uni fying theme of this third Advanced Study Institute on neutron stars. Different types of neutron star activity have been proposed to follow one another in stages during the lives of neutron stars in the same basic population; the evolutionary connection between low-mass X-ray binaries and millisecond radio pulsars is perhaps the prime example.




The Hundred Greatest Stars


Book Description

While there are guides to the visible sky, this is the first book to encompass the most important stars known in the universe at a level accessible to the layperson. The noted astronomer James Kaler takes us on a tour of the 100 most interesting stars, describing their characteristics and importance in words and vivid pictures. James B. Kaler is an internationally recognized expert on stars and their formation. A professor of astronomy at the University of Illinois, he is the author of "Stars and Their Spectra" (Cambridge), "Stars" (Freeman/Scientific American Library), "Cosmic Clouds" (Freeman/Scientific American Library), and numerous articles for popular and professional astronomy magazines.




Pulsar Astronomy


Book Description

A thoroughly revised third edition, covering recent advances in the field and including an updated catalogue of all known pulsars.







The Nature of Unidentified Galactic High-Energy Gamma-Ray Sources


Book Description

The Energetic Gamma-Ray Experiment Telescope (EGRET) instru ment on the Compton Gamma-Ray Observatory left as a legacy its Third Catalog of High Energy Gamma-Ray Sources, whose detections include a large number of blazars, some pulsars, the Large Magellanic Cloud and a solar flare. Most of the newly discovered objects - a majority of the catalog -are unidentified sources, with a clearly predominant Galactic population. Are all these radio-quiet pulsars, like Geminga, or is there a novel type of celestial object, awaiting identification? In spite of the limited angular resolution provided by EGRET and COMPTEL, there is still much to learn about unidentified ,-ray sources: correlation studies, multiwavelength observations and theoretical work can provide valuable clues, specially if these efforts are carried out in a coordinated manner. The aim of this workshop, held from October 9 to 11, 2000, at the Instituto N acional de Astrofisica, Optica y Electronica, at Tonantzintla, Mexico, was to gather experts on the subject, including observational as tronomers specialized in other regions of the electromagnetic spectrum, in an effort to address the question of the Nature of Galactic high-energy gamma-ray sources, both from the theoretical and observational perspec tive, and elaborate schemes for future identification studies which can make use of existing and forthcoming facilities.
