1mm VLBI including ALMA

Dear colleagues,

The call for 1mm Very Long Baseline Interferometry (VLBI) proposals to use phased ALMA at Band 6 in Cycle 4, in collaboration with the Event Horizon Telescope Consortium (EHTC), will be released to coincide with the ALMA Cycle 4 Call for Proposals in March 2016. The EHTC is expected to comprise the Submillimeter Array, the James Clerk Maxwell Telescope, the Submillimeter Telescope, the Atacama Pathfinder Experiment, the South Pole Telescope, the Large Millimeter Telescope Alfonso Serrano, the IRAM 30m telescope, and an antenna from the Northern Extended Millimeter Array.

The same scientific justification must be submitted in response to the ALMA and VLBI network calls. NRAO will facilitate this for the 1mm VLBI call by having proposers submit a copy of their ALMA Cycle 4 proposal in response to the 1mm VLBI call, approximately one week after the ALMA proposal deadline in April.

Further details, along with technical information for phased ALMA and the EHTC, will be made available with the 1mm VLBI Call for Proposals. It is expected that observing will take place in March or April 2017, when ALMA will be in a compact configuration suitable for efficient phasing.

Regards,
The European ALMA Regional Centre
