ALMA Invites Proposals for Early Science Observations
30. maaliskuuta 2011
The Atacama Large Millimeter/submillimeter Array (ALMA), the most ambitious radio astronomy observatory ever built, is announcing the first opportunity for the worldwide astronomical community to submit proposals for new scientific observations. Using just 16 of the 66 state-of-the-art antennas that will be in the completed array, it will already surpass the capabilities of all existing telescopes of its kind.
ALMA is getting ready to make Early Science observations. In this phase, the telescope will be used for scientific research for the first time, even though it is still under construction. Until now, observations made with the telescope have been made purely to test that its systems work as expected.
ALMA is being built in the Andes, on the Chajnantor plateau at an altitude of 5000 metres in northern Chile. By detecting light at millimetre and submillimetre wavelengths — light invisible to the human eye and optical telescopes — ALMA will revolutionise our knowledge of the cold Universe. It will observe molecular gas and dust in our galaxy and beyond, as well as the relic radiation of the Big Bang. ALMA will study the building blocks of stars, planetary systems, galaxies and life itself.
When completed in 2013, ALMA will have 54 twelve-metre diameter antennas and an additional 12 seven-metre antennas, and will be able to work as a single huge telescope over 16 kilometres in diameter, by combining the signals from the antennas. An initial 16 twelve-metre diameter antennas will be used in the Early Science phase.
The Call for Proposals issued today, 30 March 2011, invites astronomers to draw up plans for scientific projects with ALMA, and submit them to the observatory between 1 June and 30 June. Proposals will be evaluated by a group of specialists from around the world, headed by Professor Neal Evans from the University of Texas, USA, to select those expected to make best use of the Observatory, and which will generate the most valuable scientific results during this first phase of operation.
The ALMA Regional Centres — in Europe, North America, and East Asia — are responsible in their regions for providing scientific user support to astronomers who wish to use ALMA.
The Early Science observations by ALMA are planned to start around the end of September 2011, and will last about nine months. Approximately 500–700 hours of observation time will be devoted to Early Science projects, shared between the contributing partners of Europe, North America and East Asia, and the host country of Chile. During this period, the further construction and testing of the whole array will continue in parallel.
”We are keen to start scientific observations for astronomers from all over the world," says ALMA Director, Thijs de Graauw. "At the same time we are continuing to push towards our highest priority of completing the entire array, an endeavour made possible through the global ALMA partnership. There are already another 17 antennas taking shape at the observatory site, and so progress over the coming months will be very rapid.”
The ALMA project is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile.
