The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are … very favorable for high spatial resolution astronomy. At Dome C…
Submillimetre astronomy is the prime technique to unveil the birth and early evolution of stars and galaxies in the local … and distant Universe.
The unique atmospheric characteristics found at Dome C on the Antarctic plateau offer significant … advantages for the operation of adaptive optics systems.
We have developed a method for determining ICME (Interplanetary coronal mass ejection) geometry from galactic cosmic ray data recorded by the ground-based muon detector network. The … cosmic ray density depression inside the ICME, which is the cause of a Forbush decrease…
The distribution of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide … (DMSO) was examined in lead water in pack ice of the … Weddell Sea. Samples were taken by pulling water into a … syringe from a series of depths from 0.002 m to 4 m and … deeper.
Ground layer Adaptive Optics (GLAO) is a new variant of adaptive optics that aims at correcting the seeing … over a wide field of view by conjugating the deformable mirror to the boundary layer altitude.
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.
We evaluate the effect that radome transparency has on atmospheric … opacity measurements performed by the skydip technique. We show that, except at rather high opacities, it is not sufficient to ignore losses in the … radome (or “window”)…
