The Cosmic Origins Spectrograph and the Future of Ultraviolet Astronomy
I describe the capabilities of the Cosmic Origins Spectrograph, scheduled for May 2009 installation on the Hubble Space Telescope. With a factor-of-ten increase in far-UV throughput for moderate-resolution spectroscopy, COS will enable a range of scientific programs that study hot stars, AGN, and gas in the interstellar medium, intergalactic medium, and galactic halos. We also plan a large-scal...
متن کاملUltraviolet Astronomy Beyond 2020 Marc Postman and Matt Mountain
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 optical and NIR bands provide rest-UV coverage ...
متن کاملImaging performance of telescope mirrors for far-ultraviolet astronomy.
We describe image testing, surface metrology, and modeling of telescope mirrors (0.5 m in diameter, f/4.3) for the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. Laboratory image testing of wavelengths in the visible, vacuum, and midultraviolet validated a theoretical analysis by use of the Optical Surface Analysis Code (OSAC). Our modeling is based on surface metrology, including mea...
متن کاملInterchanging Interactive 3-d Graphics for Astronomy
We demonstrate how interactive, three-dimensional (3-d) scientific visualizations can be efficiently interchanged between a variety of mediums. Through the use of an appropriate interchange format, and a unified interaction interface, we minimize the effort to produce visualizations appropriate for undertaking knowledge discovery at the astronomer’s desktop, as part of conference presentations,...
متن کاملIncorporating interactive 3-dimensional graphics in astronomy research papers
Most research data collections created or used by astronomers are intrinsically multidimensional. In contrast, all visual representations of data presented within research papers are exclusively 2-dimensional. We present a resolution of this dichotomy that uses a novel technique for embedding 3-dimensional (3-d) visualisations of astronomy data sets in electronic-format research papers. Our tec...
