Available in PDF, EPUB and Kindle. Book excerpt: The Spitzer Space Observatory, originally known as the Space Infrared Telescope Facility (SIRTF), is the last of the four “Great Observatories”, which also include the Hubble Space Telescope, the Chandra X-ray Observatory, and the Compton Gamma Ray Observatory. Developed over twenty years and dubbed the “Infrared Hubble", Spitzer was launched in the summer of 2003 and has since contributed significantly to our understanding of the universe. George Rieke played a key role in Spitzer and now relates the story of how that observatory was built and launched into space. Telling the story of this single mission within the context of NASA space science over two turbulent decades, he describes how, after a tortuous political trail to approval, Spitzer was started at the peak of NASA’s experiment with streamlining and downsizing its mission development process, termed “faster better cheaper.” Up to its official start and even afterward, Spitzer was significant not merely in terms of its scientific value but because it stood at the center of major changes in space science policy and politics. Through interviews with many of the project participants, Rieke reconstructs the political and managerial process by which space missions are conceived, approved, and developed. He reveals that by the time Spitzer had been completed, a number of mission failures had undermined faith in “faster-better-cheaper” and a more conservative approach was imposed. Rieke examines in detail the premises behind “faster better cheaper,” their strengths and weaknesses, and their ultimate impact within the context of NASA’s continuing search for the best way to build future missions. Rieke’s participant’s perspective takes readers inside Congress and NASA to trace the progress of missions prior to the excitement of the launch, revealing the enormously complex and often disheartening political process that needs to be negotiated. He also shares some of the new observations and discoveries made by Spitzer in just its first year of operation. As the only book devoted to the Spitzer mission, The Last of the Great Observatories is a story at the nexus of politics and science, shedding new light on both spheres as it contemplates the future of mankind’s exploration of the universe.

This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume consists of invited lectures and seminars presented at the NATO Advanced Study Institute "The Gamma Ray Sky with COMPTON GRO and SIGMA" , which was held at the Centre de Physique Theorique of Les Houches (France) in January / February 1994. The school has been planned by a Scientific Organizing Committee. It was organized with the aim of providing students and young researchers with an up-to-date account of the high-energy phenomena in the vicinity of compact objets and the diffuse gamma-ray backgrounds after the early results from the gamma-ray telescope SIGMA and the four instruments onboard COMPTON GRO (Gamma Ray Observatory) : BATSE (Burst and Transient Source Experiment),COMPTEL(Compto'l Telescope),EGRET (Energetic Gamma Ray Experiment Telescope) and OS SE(Oriented Scintillation Spectrometer Experiment) . It was attended by more than sixty researchers from many countries. The lectures and seminars represent a complete coverage of our present knowledge and understanding of: Gamma-ray backgrounds, Gamma-ray Burts,Active Galactic Nuclei,Galactic Compact Objects, Gamma-ray Spectroscopy, Instrumentation and observation techniques, etc ... Most of these lectures are reproduced in this volume. Unfortunately, a few lecturers have chosen not to submit their manuscript.

Available in PDF, EPUB and Kindle. Book excerpt: With the Compton Gamma-Ray Observatory (CGRO) now in its ninth year of operation, the Fifth Compton Symposium provided an opportunity for sharing the most recent scientific results from CGRO and other related experiments in gamma-ray astronomy. Equally important were the descriptions of several new space-based and ground-based experiments in gamma-ray astronomy. These new instruments will be responsible for continuing the pioneering efforts of the CGRO mission. The proceedings provide a valuable reference for researchers in high energy astrophysics.

HASINGER Max-Planck-Institut flir extraterrestrische Physik, D-85740 Garching, Germany Abstract. This review describes the most recent advances in the study of the extragalactic soft X-ray background and what we can learn about its constituents. The deepest pointed observations with the ROSAT PSPC are discussed. The logN-logS relation is presented, which reaches to the faintest X-ray fluxes and to the highest AGN surface densities ever achieved. The N(>S) relation shows a 2 density in excess of 400 deg- at the faintest fluxes and a flattening below the Einstein Deep Survey limit. About 60% of the extragalactic background has been resolved in the deepest field. Detailed source spectra and first optical and radio identifications will be discussed. The results are put into perspective of the higher energy X -ray background. Key words: X-rays, background radiations, active galactic nuclei. 1. Introduction The extragalactic X-ray background (XRB), discovered about 30 years ago, has been studied extensively with many X-ray experiments, in particular with the satel lites HEAO I and II (see ego Boldt 1987) and with ROSAT (e. g. Hasinger et aI. , 1993). Figure 1 shows a compilation of some of the most recent spectral measure ments for the X-ray background. Over the energy range from 3 to about 100 keY its spectrum can be well approximated by an optically thin thermal bremsstrahlung model with kT ~ 40 keY, while at lower X-ray energies a steepening into a new component has been observed observed (e. g.
