What is Event Horizon Telescope?

This infographic details the locations of the participating telescopes of the Event Horizon Telescope (EHT) and the Global mm-VLBI Array (GMVA). Their goal is to image, for the very first time, the shadow of the event horizon of the supermassive black hole at the centre of the Milky Way, as well as to study the properties of the accretion and outflow around the Galactic Centre.

The first black hole picture was captured The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes. They are installed in six locations that essentially create a planet-sized observational dish.

The telescopes contributing to the result were:

1.ALMA , a partnership of the European Southern Observatory (ESO; Europe, representing its member states), the U.S. National Science Foundation (NSF), and the National Institutes of Natural Sciences (NINS) of Japan, together with the National Research Council (Canada), the Ministry of Science and Technology (MOST; Taiwan), Academia Sinica Institute of Astronomy and Astrophysics (ASIAA; Taiwan), and Korea Astronomy and Space Science Institute (KASI; Republic of Korea), in cooperation with the Republic of Chile.

2. APEX a telescope operated by ESO.

3. IRAM 30-meter telescope operated by IRAM. Its partner organizations are MPG (Germany), CNRS (France) and IGN (Spain)).

4. James Clerk Maxwell Telescope operated by the East Asian Observatory (EAO).

5. The Large Millimeter Telescope Alfonso Serrano operated by INAOE and UMass

6. The Submillimeter Array is operated by SAO and ASIAA;

7. The Submillimeter Telescope is operated by the Arizona Radio Observatory (ARO).

8. The South Pole Telescope is operated by the University of Chicago with specialized EHT instrumentation provided by the University of Arizona.
Petabytes of raw data from the telescopes were combined by highly specialised supercomputers hosted by the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory.
