Foreword Astrophysics at Dome C
It also includes sensitivity estimates for proposed Antarctic telescopes, as well as the parameter space such telescopes might cover if used for galaxy number count studies in the thermal IR.
متن کاملDome C atmospheric conditions: implications for astronomy
The expectation that exceptional conditions for astronomy would be found at Dome C on the high Antarctic plateau has motivated a coordinated effort by a number of international teams to comprehensively measure the atmospheric conditions at this site. This paper presents an overview of the current status of site testing at Dome C. We discuss the past, present, and planned instrumentation, the ma...
متن کاملBrightness and Extinction at Dome C , Antarctica
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. We review the contributions to sky brightness at high-latitude sites, and calculate the amount of us...
متن کاملSubmillimeter Site Testing at Dome C, Antarctica
We have developed a 350μm radiometer to perform automated site testing in remote regions of Antarctica. In summer 2000–2001 the instrument operated at Concordia, a new station under construction at Dome C on the Antarctic Plateau. We present the results, and compare them with the atmospheric opacity measured at the South Pole in the same five-week period. During these five weeks, observing cond...
متن کاملMesoscale Optical Turbulence simulations at Dome C
These last years ground-based astronomy has been looking towards Antarctica, especially its summits and the internal continental plateau where the optical turbulence appears to be confined in a shallow layer close to the icy surface. Preliminary measurements have so far indicated pretty good value for the seeing above 30-35 m: 0.36” (Agabi et al. 2006), 0.27” (Lawrence et al. 2004) and 0.3” (Tr...
