(Sub)millimeter VLBI science with ALMA

ALMA will be one of the most powerful millimeter and submillimeter ground-based observatories for many years to come. Its sensitivity and location make it an excellent candidate site for very long baseline interferometry with existing millimeter VLBI networks, including the VLBA, the Global Millimeter VLBI Array, and the Event Horizon Telescope. An international team is proposing to construct a phased-array processor to enable ALMA participation in these VLBI networks. This presentation will focus on the broad science impact of millimeter VLBI with phased ALMA on the high-resolution study of supermassive black holes, pulsars, AGN jets, and other astronomical objects.
