WSO-UV General Information
3
Why UV?
  • Most resonance transitions from ions, atoms,
    molecules of astrophysical significance are in
    the ultraviolet wavelength domain.
  • ?
  • UV provides the most sensitive tools
  • to trace the distribution of (baryonic) matter in
    the Universe,
  • to diagnose the chemical composition, physical
    properties and kinematics of astronomical objects
    of all types.

Telescope T-170
The WSO-UV telescope (T-170M) is under the
responsibility of Lavochkin Association (Russia).
Optical elements are being manufactured by the
Lytkarino Optical Glass Factory (Russia).
The main units of the structural model of the
T-170 telescope have successfully passed
vibrostatic and thermal vacuum tests.
7
The Navigator platform
  • The WSO-UV bus is the Navigator service module
    used for other Russian projects e.g. Electro
    and Radioastron that will fly before WSO-UV,
    and Spectrum X-gamma which will follow WSO-UV.
  • The Navigator of WSO-UV requires adaptation of
    radio complex, antenna-feeder system and software
    of on-board control system in terms of precision
    telescope pointing.

8
WSO-UV Orbit
  • Geosynchronous
  • Altitude 35860 km
  • Inclination 51.8

For the chosen orbit the effects of the radiation
belts will be negligible and the observing
efficiency high.

FCU vs. ACS/WFC3
  • UVO 2 times larger field of view than ACS, and 3
    times larger than WFC3/UVIS high angular
    resolution (diffraction limit _at_500nm).
    Undersampled, but sampling as for ACS and WFC3
  • FUV same field as UVO Much larger than the
    ACS/SBC field of view, (lower angular
    resolution, but still OK for many surveys)
  • NUV high angular resolution similar to ACS/SBC
    ACS/HRC, but four times larger field of view
    than ACS/SBC ACS/HRC unique spectropolarimetry
    facilities.

Hubble Deep Field UV countpart
Left A true colour image of part of the UDF the
blue and green channels are respectively GALEX
FUV (1500A, 75Ks) and GALEX NUV (2000A, 76
Ks), while the red channel is the VIMOS_at_VLT deep
imaging (36000Ks) in band U. Most of the red
"noise" are objects detected in ground based U
band imaging, but not detected in GALEX data. The
depth of GALEX data is 25-26 AB, with a PSF of
4". The size of the image is 2'x2'. Right A true
colour image with a simulation of the same field
of the previous image the blue and green
channels are the WSO-FUV and WSO-NUV
respectively, while the red is U band image.

WSO-UV Key Science Drivers
  • WSO-UV is a multipurpose telescope.
  • It will give a big contribution to answer some of
    the key questions for the next decade recently
    formulated by ASTRONET in the document Science
    Vision for the European Astronomy
  • Do we understand the extreme of the Universe?
  • How do Galaxies form and Evolve?
  • What is the origin and evolution of stars and
    planets?
  • How do we fit in?

    by the WSO consortium (more info later)
  • Open Program (OP) to the whole astronomical
