Abstract:
The AstroSat satellite is designed for multiwavelength astronomy for observations covering a
spectral range from soft and hard X-rays to the ultraviolet. The Ultraviolet Imaging Telescope (UVIT) is
the only non-X-ray telescope on AstroSat and it provides the long lever arm to the multi-wavelength observations. In addition to the simultaneous multiwavelength studies in coordination with the X-ray
telescopes on-board AstroSat, UVIT is used to study a
large variety of objects with arcsecond-level spatial
resolution. During the first year of observations,
UVIT has obtained images in many filter bands in the
wavelength range 130–300 nm over a field of ~28,
which are being used to study a variety of hot stars,
nebulae, stellar clusters and galaxies.
