VLBI Technique with EHT Telescopes

Caption

The Event Horizon Telescope (EHT) Collaboration has made the first very long baseline interferometry (VLBI) detections at 345 GHz from the surface of Earth. The new experiment used two small subarrays of the EHT—made up of ALMA and the Atacama Pathfinder EXperiment (APEX) in Chile, the IRAM 30-meter telescope in Spain, the NOrthern Extended Millimeter Array (NOEMA) in France, the Submillimeter Array (SMA) on Mauna Kea in Hawaiʻi, and the Greenland Telescope—to make measurements with resolution as fine as 19 microarcseconds.
