Hace 4 días · El telescopio colaboró con el Event Horizon Telescope (EHT), una red global de telescopios sincronizados que funcionan como un único telescopio gigante del tamaño de la Tierra.
Hace 1 día · The Event Horizon Telescope has produced resolved images of the supermassive black holes Sgr A* and M87*, which present the largest shadows on the sky. In the next decade, technological improvements and extensions to the array will enable access to a greater number of sources, unlocking studies of a larger population of supermassive black holes through direct imaging. In this paper, we ...
Hace 1 día · Telescopios como el Hubble y el Event Horizon Telescope han permitido a los científicos observar los núcleos galácticos activos y estudiar las propiedades de los discos de acreción y los jets relativistas asociados con los agujeros negros supermasivos.
Hace 1 día · In turn this means that the only energy at the event horizon is dark energy, the so-called cosmological constant. ... Webb Space Telescope captures star clusters in Cosmic Gems arc. Jun 24, 2024.
Hace 1 día · 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.
Hace 2 días · The existence of Sagittarius A* was inferred through the observation of the orbits of stars near the galactic center, which revealed the presence of a massive, invisible object exerting a strong gravitational pull. The Event Horizon Telescope (EHT) project captured an image of its event horizon, providing direct visual evidence of the black hole.
Hace 5 días · Hawking radiation is the theoretical thermal black-body radiation released outside a black hole's event horizon. This is counterintuitive because once ordinary electromagnetic radiation is inside the event horizon, it cannot escape.
