1The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of East Asia, Europe and North America in cooperation with the Republic of Chile. ALMA is funded in East Asia by the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Academia Sinica (AS) in Taiwan. In Europe ALMA is funded by the European Southern Observ...

The mission of CARA, the Center for Astrophysical Research in Antarctica, is to explore and exploit the unique conditions at the geographic South Pole and to lay the foundation for an ongoing national observatory. A small prototype user-facility instrument has demonstrated that very sensitive imaging in the thermal infrared can be routinely performed at the South Pole. The site should be furthe...

Astronomy is entering a new era as multiple, large area, digital sky surveys are in production. The resulting datasets are truly remarkable in their own right; however, a revolutionary step arises in the aggregation of complimentary multi-wavelength surveys (i.e. the cross-identification of a billion sources). Federating these different datasets, however, is an extremely challenging task. With ...

The development of the Bulgarian GRID, new possibilities for Bulgarian Virtual Observatory and some basic astronomical GRID applications from the published papers and internet are reviewed. Amongst the basic applications are N_body simulations, looking for dark matter, dark energy and neutrino, large scale structure of the Universe, stellar and galaxy evolution, active processes on the Sun, nea...

Kiwi Advanced Research and Education Network (KAREN) has been used to transfer large volumes of radio astronomical data between the Radio Astronomical Observatory at Warkworth, New Zealand and various international organizations involved in joint projects and VLBI observations. Here we report on the current status of connectivity and on the results of testing different data transfer protocols. ...

An astronomical or navigational almanac can best be thought of as a device for connecting an observer with celestial objects. For an observer with a known position and time the almanac allows the observer to identify the celestial objects. Conversely, if the observer knows what objects he is observing and when, the almanac allows him to determine his position. In either case, knowledge of the t...

We present optical WBVR and infrared JHKL photometric observations of the Be binary system δ Sco, obtained in 2000–2005, mid-infrared (10 and 18 μm) photometry and optical (λλ 3200–10500 Å) spectropolarimetry obtained in 2001. Our optical photometry confirms the results of much more frequent visual monitoring of δ Sco. In 2005, we detected a significant decrease in the object’s brightness, both...
