Download or read book Gamma Ray Astronomy from 1011 to 1014 EV Using the Atmospheric Cerenkov Technique written by N. A. Porter and published by . This book was released on 1977 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atmospheric Cerenkov technique has been widely used over the past two decades to search for point sources of 1011 to 1014 eV gamma rays. In this technique the gamma rays are detected by the Cerenkov light emission from the small air showers that they create in the atmosphere. The basic principles underlying the technique are reviewed with particular reference to the experiments performed to date, (September 1977). The production and absorption processes that pertain to this energy region are discussed. There is strong evidence for the detection of 10^12 eV gamma rays from NP0532, Centaurus A and Cygnus X-3. Models for these, and other sources for which upper limits have been derived, are outlined. There appears to be no other technique that can compete with the atmospheric Cerenkov technique in this energy range. The methods by which the present flux sensitivity can be reduced by factors of 10 - 100 are discussed; it is also possible to extend observations into the previously unexplored 10 - 100 Gev energy range.

This book was released on 1968 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gamma-ray detector consisting of scintillation counters and a spark chamber to convert gamma rays to electron-positron pairs was flown with a balloon to an altitude of 125,000 feet for 7 hours on 28 May 1966. The photon spectrum at 4 g cm-2 atmospheric depth is reported. The angular resolution of the detector and method of determining statistical upper limits of fluxes are thoroughly discussed.

This book was released on 2005-12-05 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly one half of the point-like gamma-ray sources detected by EGRET instrument of the late Compton satellite are still defeating our attempts at identifying them. To establish the origin and nature of these enigmatic sources has become a major problem of current high-energy astrophysics. The second workshop on Multiwavelength Approach to Unidentified Gamma-ray Sources intends to shed new and fresh light on the problem of the nature of the unidentified gamma-ray sources. The proceedings contain 46 contributed papers in this subject, which cover theoretical models on gamma-ray sources as well as the best multiwavelength strategies for the identification of the promising candidates. The topics of this conference also include energetic phenomena occurring both in galactic and extragalactic scenarios, phenomena that might lead to the appearance of what we have called high-energy unidentified sources. The book will be of interest for all active researchers in the high-energy astrophysics and related research areas as well as for scientists and graduate students interested in understanding the recent progress in high-energy astrophysics.

This book was released on 2007-10-02 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research program in gamma-ray astronomy focuses on increasing our knowledge of the nature and origin of galactic and extragalactic gamma rays, and understanding high-energy processes in the Sun, celestial objects, interstellar medium, and extragalactic space.This book not only provides an overview of the latest research and future plans for space-borne and ground-based experiments dedicated to the observation of the gamma-ray sky, but also addresses the topic of variable gamma-ray sources from the perspective of their identification and counterparts at different wavelengths. It further gives an overview of the theory related to the most qualified emission processes that take place in these sources and of the nature of their variability.
