WSO-UV—ultraviolet mission for the next decade

Abstract

The World Space Observatory UltraViolet (WSO-UV) is an international space mission devoted to UV spectroscopy and imaging. The observatory includes a 170 cm aperture telescope capable of high-resolution and long slit low-resolution spectroscopy, and deep UV and optical imaging. The observatory is designed for observations in the ultraviolet domain where most of astrophysical processes can be efficiently studied with unprecedented capability.

Searching for FUV line emission from 107 K gas in massive elliptical galaxies and galaxy clusters as a tracer of turbulent velocities

“…For example, the Reflection Grating Spectrometer on XMM-Newton has an effective area of up to ∼ 150 cm 2 and the Soft X-ray Spectrometer on Hitomi had ∼ 200 cm 2 , while COS has more than 2000 cm 2 with the medium-resolution gratings. Proposed future UV spacecraft such as the World Space Observatory (Shustov et al 2009) or the Public Telescope 2 will retain or improve upon the spectral resolution of COS, but these missions do lack the large collecting area of HST.…”

GALEX catalogs of UV sources: statistical properties and sample science applications: hot white dwarfs in the Milky Way

“…HST STIS and COS, WFC3) and future UV missions on large scale (e.g. WSO, Shustov et al 2009) and small scale like UVIT on ISRO Astrosat, rocket flights (e.g. McCandliss et al 2005) and long-duration-flight ballons.…”

UV-controlled physical and chemical structure of protoplanetary disks

“…Influence of UV irradiation onto the disk structure gets stronger as dust particles grow bigger at the initial phase of planet formation. Thus, in order to interpret observations of a particular star+disk system its UV spectroscopy in the range of 1000 − 3000Å is greatly important, which makes future missions like WSO-UV highly desirable (Shustov et al 2009(Shustov et al , 2011.…”
