[44.03] OVI Spectroscopy with SPIDR

The Spectroscopy and Photometry of IGM's Diffuse Radiation (SPIDR) mission will utilize six single-element imaging spectrographs to observe UV emission from the Warm-Hot Intergalactic Medium (WHIM). Several coded slit arrangements are currently under consideration, with the goal of maximimizing sensitivity to emission in the OVI doublet. We present here a study of the different slit configurations. We use matched filter analysis and Markov Chain Monte Carlo simulations, and include realistic values of the Galactic background and Lyman alpha scattering over a wide range of OVI doublet strengths. We briefly discuss its impact on SPIDR's ability to detect the WHIM over a broad range of redshift. Support for this study has been provided by NASA Contract NAS 5-03013.
