The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
First combined image reconstruction of the event horizon of a black hole captured by the Event Horizon Telescope.[1]CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) is a Bayesian algorithm used to perform a deconvolution on images created in radio astronomy.
Katherine Louise Bouman (/ ˈ b aʊ m ə n /; [1] born 1989) is an American engineer and computer scientist working in the field of computational imaging.She led the development of an algorithm for imaging black holes, known as Continuous High-resolution Image Reconstruction using Patch priors (CHIRP), and was a member of the Event Horizon Telescope team that captured the first image of a ...
To create the footage, the Event Horizon Telescope team — the research group behind the discovery of the original black hole image — dug out old data and combined it with a mathematical model ...
The image (or "map") of the source is produced from these measurements. Astronomical interferometers are commonly used for high-resolution optical, infrared, submillimetre and radio astronomy observations. For example, the Event Horizon Telescope project derived the first image of a black hole using aperture synthesis. [4]
Radio Galaxy Zoo (RGZ) is an internet crowdsourced citizen science project that seeks to locate supermassive black holes in distant galaxies. [ 1 ] [ 2 ] It is hosted by the web portal Zooniverse . The scientific team want to identify black hole/jet pairs and associate them with the host galaxies.
Some of the Atacama Large Millimeter Array radio telescopes The eight radio telescopes of the Smithsonian Submillimeter Array, located at the Mauna Kea Observatory in Hawai'i VLBI was used to create the first image of a black hole, imaged by the Event Horizon Telescope and published in April 2019.

Cygnus X-1 (abbreviated Cyg X-1) [11] is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole. [12] [13] It was discovered in 1964 during a rocket flight and is one of the strongest X-ray sources detectable from Earth, producing a peak X-ray flux density of 2.3 × 10 −23 W/(m 2 ⋅Hz) (2.3 × 10 3 jansky).
