We present low-resolution turbulence proles of the atmosphere above Dome C, Antarctica, measured with the MASS instrument during 25 nights in March { May 2004. Except for the … lowest layer, Dome C has signicantly less turbulence than Cerro Tololo and Cerro Pachon. In … particular…
PILOT (Pathfnder for an International Large Optical Tele- … scope) is a proposed 2 m class optical/infrared telescope to be sited … at Dome C on the Antarctic plateau. Recent site testing results from … Dome C have shown remarkable ground level seeing, a large isoplanatic … angle…
Over the past decade we have developed a series of increas- … ingly sophisticated robotic instruments for site testing in Antarctica. These range from exceedingly low power cloud monitors to fully au- … tonomous 30 cm telescopes, and cover from the ultraviolet to the sub- … mm.
The recent discovery of exceptional seeing conditions at Dome C, Antarctica, raises the possibility … of constructing an optical observatory there with unique capabilities. However, little is known from an astronomer’s … perspective about the optical sky brightness and extinction at Antarctic sites.
Dome C, Antarctica (75 S, 123 E; 3250 meters) is one of the coldest and driestlocations on Earth, with exceptionally low winds throughout the atmosphere. It therefore has the potential to be an ideal site for astronomical observations.
Astronomers have always sought the very best locations for their telescopes. From … observatories in city centres, astronomers moved first to nearby mountain tops, then to … remote sites in distant countries, to aircraft, and into space.
The AASTINO (Automated Astrophysical Site Testing INternational Observatory) is a remote … laboratory that has been operating at Dome C station on the Antarctic plateau since January 2003. It … is designed to run throughout the Antarctic winter without intervention…
The Antarctic Plateau Interferometer (API) is an instrument concept capable of extensive unique discovery space science in a variety of areas including exoplanets, accretion, YSO's, and AGNs. To study exoplanets in the habitable zone, API would use three 2 meter class telescopes…
Abstract. Due to the typical high atmospheric noise and low opacity, submillimeter observations … can be carried out only from sites with very high atmospheric stability and very … low precipitable water vapour content.
The Antarctic Fibre-Optic Spectrometer (AFOS) is a 30cm Newtonian optical telescope that injects light through … six 30m long optical ¯bres onto a 240¡850nm spectrograph with a 1024 x 256 pixel CCD camera.
To properly characterize the atmospheric properties of a site for a future large telescope or interferometer, it is insufficient to … measure quantities, such as the full-width at half-maximum of a stellar image, that have been integrated over the entire … atmosphere.
The perfect site for astronomical interferometry would be one where the wind speeds throughout the atmosphere were … very low, there was little atmospheric turbulence (especially at high altitudes), the seismic activity was negligible and … the climate very stable. Perhaps surprisingly…
The primary limitation to ground based astronomy is the Earth's atmosphere. The atmosphere above the … Antarctic plateau is fundamentally dierent in many regards compared to the atmosphere at temperate sites. The … extreme altitude…
Abstract. A good astronomical site must fulfill several criteria including low atmospheric turbulence and low wind speeds. is therefore important to have a detailed knowledge of the temperature and wind conditions of a location considered for future … astronomical research.
Abstract. The high plateau that covers half of the continent of Antarctica contains the best astronomical observing sites … on Earth. The infrared sky background is low, the precipitable water vapour is low, the sub-millimetre sky opacity is low, the winds are low…
