![]() ![]() The image has been unveiled by JIVE Chief Scientist and EHT Project Director Huib Jan van Langevelde at the European Southern Observatory Headquarters in Garching (Germany), one of the press conferences organised by the EHT Collaboration around the world. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration - including participation in the Netherlands of astronomers and technicians from University of Amsterdam, Radboud University, Leiden University, University of Groningen, JIVE ERIC and ASTRON - using observations from a worldwide network of radio telescopes. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies. The EHT data processing occurs in two pipelines for cross verification, one of which ( rPicard) is based on CASA and the tools developed at JIVE.Īstronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. The work in JIVE focuses on the data management and calibration of EHT observations, including the development of new software components in the CASA package. In 2022 the centre of our own Galaxy was shown to harbour a million solar mass black hole, Sagittarius A*. In april 2019 the billion solar mass black hole in the core of the nearby massive elliptical galaxy M87 was revealed (Pōwehi). The EHT has published the first two images of supermassive black holes. (There is a supermassive black hole at the center of our galaxy the Milky Way. It utilises Very Long Baseline Interferometry (VLBI) at higher frequencies (100-350GHz) than the European VLBI Network, which operates in the 1-43 GHz regime. Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of the galaxy M87. In active galaxies where the central black hole is not resolved, the EHT enables studies of jets and jet formation mechanisms at the smallest physical scales. The gravity is so strong because matter (the mass) has been squeezed into a tiny space.The Event Horizon Telescope (EHT) is an international collaboration - including over 300 scientists from more than 20 countries - capturing images of black holes using a virtual Earth-sized telescope. The Event Horizon Telescope (EHT) a planet-scale array of eight ground-based radio telescopes forged through international collaboration was designed to capt ure images of a black hole. What is a Black Hole?Ī black hole is a dense, compact object whose gravitational pull is so strong that – within a certain distance of it – nothing can escape, not even light.īlack holes are thought to result from the collapse of very massive stars at the ends of their evolution. The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. The shadow is essentially an image of the event horizon, lensed by the strong gravitational field around the BH (which bends the path of light rays, acting as a. The black hole is outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon. (There is a supermassive black hole at the center of our galaxy - the Milky Way.) Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of the galaxy M87. The short linear feature near the center of the image is a jet produced by the black hole. This image was captured by FORS2 on ESO's Very Large Telescope. The supermassive black hole imaged by the EHT is located in the center of the elliptical galaxy M87, located about 55 million light years from Earth. ![]()
