The Event Horizon Telescope is a project to create a telescope array combining data from VLBI stations around the Earth to observe the immediate environment of the Milky Way's supermassive black hole Sagittarius A* with angular resolution comparable to the event horizon.[1][2][3]
The group proposes till 2022 to combine existing and planned millimeter/submillimeter facilities into a high-sensitivity, high angular resolution Event Horizon Telescope. The effort will include development and deployment of submillimeter dual polarization receivers, highly stable frequency standards to enable VLBI at 230–450 GHz, higher-bandwidth VLBI backends and recorders, as well as commissioning of new submillimeter VLBI sites.[4]
