ALMA is not only a powerful interferometer on its own, its sensitivity in cooperation with other radio facilities worldwide also enables spectacular advances at angular resolutions of tens of microarcseconds. In the phased array mode, the signals of the ALMA 12m-array antennas are summed to observe as one large single dish antenna.

This tutorial will provide an introduction to the mm VLBI mode with the phased ALMA array as part of the Global Millimeter VLBI Array (GMVA) in Bands 1 and 3 or as part of the Event Horizon Telescope (EHT) in Bands 6 and 7. It will start with an overview of the main science drivers for mm VLBI, followed by a detailed explanation on how to prepare a VLBI proposal with ALMA, including the proposals that are to be submitted to the mm VLBI network operators.

The duration of this training session will be about one hour followed by a Q&A session. If you have any questions, please contact Kazi Rygl at kazi.rygl@inaf.it.

Tutors: Kazi Rygl, Violette Impellizzeri, Stefanie Muehle, Katharina Immer

Note: The tutor's presentation will be recorded and an edited version of the recording will be posted in the Science Portal [I-TRAIN] after the session. The interactive Q&A will not be recorded.
