Spectral and polarimetric facilities for ground support of the WSO-UV Space mission

摘要

The World Space Observatory-Ultraviolet (WSO-UV) is a Russian-Spanish space mission born as a response to the growing up demand for UV facilities by the astronomical community. WSO-UV mission will make observations with spectrographs and imagers in UV domain (115-310 nm). For many astrophysical tasks of the mission Core program high resolution spectroscopic observations (R = 50000) will require ground support spectroscopic observations in spectral domain of 300-1000 nm. For these purposes we are upgrading existing facilities of Special Astrophysical Observatory, including NES, ESPRI and CAES spectrographs, and installing new ones. Nesmith Echelle Spectrograph (NES) of 6-m telescope with its fused silica optics allows to get spectra with R=70000 in 310-800 nm spectral region. We estimate its instrumental polarization on the 3-th flat mirror. Echelle Spectrograph of PRImary focus (ESPRI) for faint object spectrapolarimetry with R=25000 is under construction now. The 1-m telescope will be equipped by Cassegrain echelle spectrograph CAES. Here we present detail information on such instrumentation and our recent achievements. This paper provides an information on instrumentation update.
