ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA) is composed of 66 antennas located in northern Chile on the Chajnantor Plateau at an altitude of 5000 m an a latitude of -23 degrees.  The dryness and stability of the air at this location make it ideal for observing millimetre and submillimetre radiation from astronomical objects.  The telescope, which began science observations in 2011, was constructed and is operated by an international collaboration including Europe (represented by the European Southern Observatory), North America (represented by the National Radio Astronomy Observatory), East Asia (represented by the National Astronomical Observatory of Japan), and Chile, with activities coordinated by the Joint Astronomy Centre in Santiago, Chile.

UK ALMA Regional Centre Node

The UK ALMA Regional Centre (UK ARC), which is hosted by the Jodrell Bank Centre for Astrophysics (JBCA) at the University of Manchester and which is part of the Interferometry Centre of Excellence, provides support for UK scientists using the telescope.  The STFC-funded collaborative project also includes contributions from Cambridge University, Oxford University, the UK Astronomy Technology Centre (ATC) and the STFC Rutherford Appleton Laboratory. 

 

UK ARC Node Activities

The UK ARC supports ALMA users with multiple services including the following:

  • Proposal planning and submission
  • Observation preparation
  • Enhanced data reduction and andanced analysis
  • Dedicated high-end computer facilities
  • Workshop and meeting organisation
  • Informational monthly mailings on the status of ALMA
  • Support of the ALMA Observation Support Tool

 

 The UK ARC has also been involved with technical development for ALMA, including the following:

  • Optical fibres and data transmission system
  • Waver vaour radiometer for phase correction
  • Band 2/3 system
  • Observing Tool
  • Data processing pipeline
  • Simulations (including the Observation Support Tool)
  • Science archive
