Ultraviolet and X-Ray Astronomy

open access: closed, 2016
This chapter discusses the astrophysics with photons having an energy up to hundreds of keV. X-rays are not able to penetrate atmosphere and space based observatories are needed. Telescopes for UV and softX-rays use reflective elements based on grazing incidence.

Galactic ultraviolet astronomy

Reports on Progress in Physics, 1987
A general presentation of astrophysical observations in the ultraviolet is given. First the particular nature of ultraviolet studies is emphasises. This is followed by a brief historical presentation of some of the typical instrumentation used. Then, in the framework of galactic observations, some of the most important results obtained concerning the ...

Ultraviolet Astronomy Beyond 2020

AIP Conference Proceedings, 2009
UV astronomy has a promising long‐term future if astronomers think boldly about where the next frontiers lie in this rich field. The most exciting of these frontiers involve resolving structures near or below angular scales of 20 mas and/or obtaining modest resolution spectroscopy of nanoJansky sources across the 0.11–2.5 μm wavelength range (the ...

Aspheric grating for extreme ultraviolet astronomy

Applied Optics, 1978
A family of plane curves is developed which can diffract incident parallel rays to a point focus. These curves, termed diffractoidal curves, are rotated around an axis to produce surfaces of revolution correspondingly termed diffractoids, whose imaging properties for sources at infinity are studied by ray tracing in a few examples.

Skylab ultraviolet stellar astronomy experiment S019

Applied Optics, 1977
An objective-prism stellar spectrograph of 15-cm aperture was flown on all three Skylab missions. The wavelength region from 1300 A to 5000 A was covered by a special optical system containing a combination of reflecting telescope optics, a CaF(2) objective prism, and an achromatized field corrector lens system of CaF(2) and LiF.

Extreme Ultraviolet Astronomy

2003
This text describes the development of astronomy in the Extreme Ultraviolet (EUV) wavelength range, from the first rocket-based experiments in the late 1960s through to later satellite missions. Discussions of the results from important space projects are followed by an analysis of the contributions made by EUV astronomy to the study of specific groups

Galactic Astronomy in the Ultraviolet

Solar System Research, 2017
We propose a number of prospective observational programs for the ultraviolet space observatory WSO-UV, which seem to be of great importance to modern galactic astronomy. The programs include the search for binary Cepheids; the search and detailed photometric study and the analysis of radial distribution of UV-bright stars in globular clusters (“blue ...
