Atacama Large Millimeter/submillimeter Array research & development

The Atacama Large Millimeter/submillimeter Array (ALMA) is the world’s most powerful radio telescope and the largest ground-based astronomy endeavour ever undertaken. Located high in the Chilean Andes, ALMA is composed of 66 12-metre and 7-metre high-precision radio antennas that work together at millimetre and submillimetre wavelengths.

Funded and operated by an international partnership involving 22 countries from North America, Europe, East Asia, and South America, ALMA lets astronomers observe phenomena that were previously out of reach, providing new insight into the origin and formation of galaxies, stars, and planets.

ALMA is a revolutionary instrument in its scientific concept, its engineering design and its organization as a global scientific endeavour. The National Research Council (NRC) collaborates with the U.S. National Radio Astronomy Observatory as part of the North American component of ALMA. In this role, NRC is involved in governance and operational support of the astronomy community, including facilitating telescope access for Canadian researchers, and collaborating with industry and other research partners on new and novel instrumentation.

Collaboration Opportunities

While the Joint ALMA Observatory (JAO) is responsible for the overall leadership and management of the telescope, three international ALMA Regional Centres (ARC) provide an interface between ALMA and the astronomy community. Astronomers at Canadian institutions are supported by the North American ALMA Science Center (NAASC) based in Charlottesville, VA with additional support from a team based at NRC’s Dominion Astronomical Observatory (DAO) in Victoria, BC. NRC also collaborates with other ARCs located in Europe and East Asia.

Technology in support of science: instrumentation projects

As part of the construction, commissioning, and operation of ALMA, NRC works with industry and universities to develop new and ever more powerful astronomical technology. NRC has worked on several technical components of the ALMA telescope, developing innovative technologies that make ALMA’s unique capabilities possible.

Today, NRC remains engaged with ALMA technology development. Canada’s most recent collaborative technology developments include a design study for a millimetre camera and a project to improve the power stability of the ALMA Band 3 receiver using permanent magnets.

Advancing our understanding of the universe: science projects

Since early science research began at ALMA in September 2011 it has expanded our knowledge of the known universe. ALMA enables transformational research into the physics of the cold universe, regions that are optically dark but emit strongly in the millimetre portion of the electromagnetic spectrum. Providing astronomers a new window on celestial origins, ALMA probes the first stars and galaxies and directly images the disks in which planets are forming. Through current collaborative research projects, NRC is advancing scientific knowledge through projects focused on star formation, molecular clouds, the solar system and the early universe.
