Download or read book Cosmic Gamma-Ray Sources written by K.S. Cheng and published by Springer Science & Business Media. This book was released on 2012-11-03 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray astronomy has undergone an enormous progress in the last 15 years. The success of satellite experiments like NASA's Comp ton Gamma-Ray Observatory and ESA's INTEGRAL mission, as well as of ground-based instruments have open new views into the high-energy Universe. Different classes of cosmic gamma-ray sources have been now detected at different energies, in addition to young radio pulsars and gamma-ray bursts, the classical ones. The new sources include radio quiet pulsars, microquasars, supernova remnants, starburst galaxies, ra dio galaxies, flat-spectrum radio quasars, and BL Lacertae objects. A large number of unidentified sources strongly suggests that this brief enumeration is far from complete. Gamma-ray bursts are now estab lished as extragalactic sources with tremendous energy output. There is accumulating evidence supporting the idea that massive stars and star forming regions can accelerate charged particles up to relativistic ener gies making them gamma-ray sources. Gamma-ray astronomy has also proved to be a powerful tool for cosmology imposing constraints to the background photon fields that can absorb the gamma-ray flux from dis tant sources. All this has profound implications for our current ideas about how particles are accelerated and transported in both the local and distant U niverse. The evolution of our knowledge on the gamma-ray sky has been so fast that is not easy for the non-specialist scientist and the graduate student to be aware of the full potential of this field or to grasp the fundamentals of a given topic in order to attempt some original contribution.

Book Synopsis Very High Energy Cosmic Gamma Radiation by : Felix A. Aharonian
Download or read book Very High Energy Cosmic Gamma Radiation written by Felix A. Aharonian and published by World Scientific. This book was released on 2004 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma ray astronomy, the branch of high energy astrophysics that studies the sky in energetic Ýgamma¨-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. This book presents the motivations and highlights the principal objectives of the field, as well as demonstrates its intrinsic links to other branches of high energy astrophysics. Preference is given to three topical areas: (i) origin of cosmic rays: (ii) physics and astrophysics of relativistic jets: (iii) observational gamma ray cosmology. Also, a significant part of the book is devoted to the discussion of the principal mechanisms of production and absorption of energetic Ýgamma¨-rays in different astrophysical environments, as well as to the description of the detection methods of high energy cosmic Ýgamma¨- radiation.
Book Synopsis Cosmic Rays at Earth by : P.K.F. Grieder
Download or read book Cosmic Rays at Earth written by P.K.F. Grieder and published by Elsevier. This book was released on 2001-07-27 with total page 1112 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery. Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal evolution. For example, the development of new fields of research such as elementary particle physics, modern astrophysics and cosmology are direct consequences of this discovery. Over the years the field of cosmic ray research has evolved in various directions: Firstly, the field of particle physics that was initiated by the discovery of many so-called elementary particles in the cosmic radiation. There is a strong trend from the accelerator physics community to reenter the field of cosmic ray physics, now under the name of astroparticle physics. Secondly, an important branch of cosmic ray physics that has rapidly evolved in conjunction with space exploration concerns the low energy portion of the cosmic ray spectrum. Thirdly, the branch of research that is concerned with the origin, acceleration and propagation of the cosmic radiation represents a great challenge for astrophysics, astronomy and cosmology. Presently very popular fields of research have rapidly evolved, such as high-energy gamma ray and neutrino astronomy. In addition, high-energy neutrino astronomy may soon initiate as a likely spin-off neutrino tomography of the Earth and thus open a unique new branch of geophysical research of the interior of the Earth. Finally, of considerable interest are the biological and medical aspects of the cosmic radiation because of it ionizing character and the inevitable irradiation to which we are exposed. This book is a reference manual for researchers and students of cosmic ray physics and associated fields and phenomena. It is not intended to be a tutorial. However, the book contains an adequate amount of background materials that its content should be useful to a broad community of scientists and professionals. The present book contains chiefly a data collection in compact form that covers the cosmic radiation in the vicinity of the Earth, in the Earth's atmosphere, at sea level and underground. Included are predominantly experimental but also theoretical data. In addition the book contains related data, definitions and important relations. The aim of this book is to offer the reader in a single volume a readily available comprehensive set of data that will save him the need of frequent time consuming literature searches.

Book Synopsis Cosmic Gamma Rays by : Floyd William Stecker
Download or read book Cosmic Gamma Rays written by Floyd William Stecker and published by . This book was released on 1971 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The scientific potential of y-ray astronomy has long been recognized from a theoretical standpoint by investigators in the fields of cosmic-ray research and high-energy astrophysics. Gamma-ray studies can help answer questions concerning the nature and origin of cosmic rays, both galactic and extragalactic : the nature of supernovae, pulsars, and powerful radio sources; the extent and importance of antimatter in the universe; and the nature of the universe in the distant past. The advent of satellite-borne y-ray telescopes has recently made y-ray astronomy a reality. The first observations, as discussed in this book, have already provided important information on galactic and extragalactic cosmic rays and interstellar gas. These observations may also have great cosmological significance. The second generation of y-ray telescopes is already in the development stage. It therefore seems most appropriate at this time for a comprehensive theoretical monograph."--Page iii.

Book Synopsis Very High Energy Gamma-Ray Astronomy by : T.C. Weekes
Download or read book Very High Energy Gamma-Ray Astronomy written by T.C. Weekes and published by CRC Press. This book was released on 2003-04-08 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: High energy gamma-ray photons are the prime probes of the relativistic or high-energy universe, populated by black holes, neutron stars, supernovae, quasars, and matter-antimatter annihilations. Through studying the gamma-ray sky, astrophysicists are able to better understand the formation and behavior of these exotic and energetic bodies. Very High Energy Gamma-Ray Astronomy summarizes the status of gamma-ray astronomy at energies between 30MeV and 50TeV at a critical point in the development of the discipline: the hiatus between the demise of the EGRET telescope and the launch of the next generation of space telescopes. Starting with an overview of the astrophysics of the bodies that generate high energy gamma rays, it proceeds to discuss the latest developments in observational techniques and equipment. By presenting the techniques, observations, and theories of this expanding frontier, Very High Energy Gamma-Ray Astronomy aids experimentalists and theoreticians in detecting and explaining gamma rays of the highest energies.
