European ARC nodes and Centre of Expertise


The European ALMA Regional Centre (ARC) provides the interface between the Atacama Large (sub-)Millimetre Array (ALMA) project and the European science community. Support to the European science community is provided by a distributed network of ARC nodes throughout Europe located in Bologna, Bonn/Cologne, Grenoble, Leiden, Manchester, Ondrejov and Onsala under the coordination of the European Southern Observatory in Garching. ARC nodes provide support to the whole European community in the form of:

  • Extended archive and data reduction support: face-to-face data processing support in a dedicated physical location, modified pipelineversions, re-processing of large and/or complex datasets, advanced simulation development, advanced algorithm development and use, help with archival research projects
  • Support with proposal preparations and support for special projects such as large programs
  • Science community development: support for ALMA research (e.g.,basic training for new users), post-doctoral fellowships, training schools and workshops, ALMA-related specific science workshops, leading science community development activities with ad-hoc assistance from the ESO ARC and advanced public outreach activities
