Abstract

Astronomical surveys have demonstrated an enormous capability for increasing our understanding of the universe around us. There are significant wavelength regions, which for various reasons are poorly sampled. Powerful diagnostics of hot gas in the universe are well understood, but there are few instruments capable of making measurements at the wavelengths of the most important lines (103 nm, 123 nm, and 155 nm, the lithium-like series of O, N, and C). No complete survey has been done with moderate spatial resolution in emission even though virtually all measurements capable of detecting the presence of lithium-like oxygen do so. We present a technique to eliminate the spectral-spatial confusion inherent in a wide field imaging spectrograph based on a type of imaging spectrograph that takes advantage of the large, well-corrected field of view from a three-mirror anastigmat (TMA) in conjunction with aberration-corrected holography applied to the tertiary.
