Solar observing with the Atacama large millimeter-submillimeter array

The Inauguration of the Atacama Large Millimeter/submillimeter Array

The Atacama Large Millimeter / Submillimeter Array 1 Development Program

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 Atacama Large Millimeter Array (ALMA)

The Atacama Large Millimeter Array, or ALMA, is an international telescope project which will be built over the coming decade in Northern Chile. With over 7000 m of collecting area comprised of 64 12m antennas arrayed over baselines up to 14 km in extent, ALMA will provide images of unprecedented clarity and detail. One revolutionary feature of ALMA will be its ability to combine interferometri...

Science with the Atacama Large Millimeter

Extensive post-main sequence mass loss occurs for low and intermediate mass stars on the asymptotic giant branch (AGB), and for the higher mass stars during their red supergiant evolution. These winds aaect the evolution of the stars profoundly, as well as the enrichment of the interstellar medium with heavy elements and grain particles. The mass loss on the AGB is the by far the most well stud...

ALMA Memo No. 374 Wide Field Imagings with the Atacama Large Millimter/ Submillimeter Array

Image quality of wide field observations with the ALMA has been studied with imaging simulations. Results of the simulations showed that antenna pointing errors are a serious problem for obtaining high quality images because they make a large error in visibilities in the central (u,v) hole estimated by mosaicing data processings. The ALMA Compact Array (ACA) with more than 10 smaller dishes (6-...
