24 de jul. de 2024 · Already, the Event Horizon Telescope (EHT) has resolved the horizon of the black holes at the center of the Milky Way and M87. A team of astronomers is now looking to the next generation of...
Há 4 dias · Mar. 24, 2021 — The Event Horizon Telescope (EHT) has produced a new image showing details of the magnetic fields in the region closest to the supermassive black hole at the core of the galaxy...
17 de jul. de 2024 · An image of the supermassive black hole at the center of the Milky Way, a behemoth dubbed Sagittarius A*, revealed by the Event Horizon Telescope on May 12, 2022.
Há 1 dia · The Event Horizon Telescope (EHT) is an active program that directly observes the immediate environment of black holes' event horizons, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observing the black hole at the centre of Messier 87 .
16 de jul. de 2024 · The Event Horizon Telescope (EHT) has imaged two supermassive black holes, Messier 87* (M87*) and Sagittarius A* (Sgr A*), using very-long-baseline interferometry (VLBI). The theoretical analyses of each source suggest magnetically arrested disk (MAD) accretion viewed at modest inclination. These MADs exhibit
5 de ago. de 2024 · Haystack serves as a computational hub for the Event Horizon Telescope, an assemblage of radio telescopes around Earth that combine data for very-long-baseline interferometry (VLBI) to achieve angular resolution capable of imaging a supermassive black hole's event horizon.
Há 6 dias · We argue that the Event Horizon Telescope images of M87 ^ {\star} ⋆ and Sgr A ^ {\star} ⋆ rule out the baseline version of mimetic gravity, preventing the theory from successfully accounting for the dark sector on cosmological scales. Our results highlight an interesting complementarity between black hole imaging observations and modified ...
