X-ray astronomy, Study of astronomical objects and phenomena that emit radiation at X-ray wavelengths. Because Earth’s atmosphere absorbs most X-rays, X-ray telescopes and detectors are taken to high altitudes or into space by balloons and spacecraft. 63 NASA TM, William W.

Vaughan and W. Greene. The Advanced X-ray Astrophysics Facility (AXAF) will be a long-lived observatory intended to carry out X-ray studies from space. Much of the design for AXAF has been predicated on the highly successful HEAO-2/ Einstein X-ray observatory that NASA operated from until Author: Harvey Tananbaum.
The Advanced X-ray Astrophysics Facility (AXAF) Martin C. Weisskopf and Stephen L. O’Dell NASA, Marshall Space Flight Center and Leon Van Speybroeck Smithsonian Astrophysical Observatory ABSTRACT AXAF is an x-ray observatory designed to study x-ray emission from all categories of astronomical objects — from normal stars to quasars.
The Advanced X-ray Astrophysics Facility (AXAF) planned for launch in the middle of the next decade will be a powerful new tool to enhance our understanding of the Universe. In this paper we describe the principal elements: the optics and the instruments. We review the instrument capabilities in order that potential users of AXAF may plan supporting research in the years prior to by: TRW (): Advanced X-ray Astrophysics Facility Technical Presentation Papers.
Spina, John A. (): Design, Fabrication and Assembly of the High Resolution Mirror Assembly for NASA's Advanced X-ray Astrophysics by: 4. NASA's Advanced X-ray Astrophysics Facility (AXAF) will be an orbiting X-ray observatory, designed to address fundamental questions in astronomy and astrophysics.
AXAF is an x-ray observatory designed to study x-ray emission from al categories of astronomical objects, from normal stars to quasars. AXAF has broad scientific objectives and outstanding capability to provide high resolution images, spectrometric imaging and high resolution dispersive spectroscopy over the energy bandwidth from to by: The Advanced X-ray Astrophysics Facility (AXAF) will be the third satellite in the series of great observatories in the NASA programme, after the Hubble Space Telescope and the Gamma Ray Observatory.
The anticipated launch date of AXAF is Cited by: 1. Reflectivity and scattering profile measurements were made on a gold-coated witness sample produced to evaluate mirror coatings for the Advanced X-ray Astrophysics Facility program.
Reflectivity measurements were made at Al K, Ti K, and Cu K energies as a function of incident graze angle. The results are fit to a model that includes the effects of roughness, particulate and organic.

X-ray astronomy probes some of the highest energy processes in the Universe that are powered by gravity. These include accretion onto compact objects (black holes, neutron stars, etc.), evolution and mergers of galaxy clusters and bursts of star formation in galaxies.

All backorders will be released at the final established price. As a courtesy, if the price increases by more than $ we will notify you.The most compelling nature of X-ray astronomy is its richness and scale. Almost every observable object in the sky either naturally emits X-ray radiation or can be probed by X-ray absorption.
