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.
She is the Modeling lead and member of the Event Horizon Telescope (EHT) that released the first image of a black hole. [3] [4] Özel received the Maria Goeppert Mayer award from the American Physical Society in 2013 [5] for her outstanding contributions to neutron star astrophysics.
He is involved in the Event Horizon Telescope project, [2] which led in 2019 to the first image of the event horizon of a black hole. [3] [4] [5] The first image of the event horizon of a black hole, captured by the Event Horizon Telescope collaboration.
In April 2019, the Event Horizon Telescope collaboration released measurements of the black hole's mass as (6.5 ± 0.2 stat ± 0.7 sys) × 10 9 M ☉. [74] This is one of the highest known masses for such an object. A rotating disk of ionized gas surrounds the black hole, and is roughly perpendicular to the relativistic jet.
OJ287 is a target candidate of the Event Horizon Telescope, 3C279 was targeted by it in 2017. The optical light curve shows that OJ 287 has a periodic variation of 11–12 years with a narrow double peak at maximum brightness. [8] This kind of variation suggests that it is a binary supermassive black hole. [9]
In astrophysics, an event horizon is a boundary beyond which events cannot affect an outside observer. Wolfgang Rindler coined the term in the 1950s. [1]In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape. [2]
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.
English: The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole.
