Há 3 dias · These are the two largest black holes we know about and the Event Horizon Telescope has just captured stunning images of their event horizons. A new paper looks at what we might expect from a next generation EHT and highlights twelve targets that should be top of the list.
Há 3 dias · Hunting for extra dimensions in black hole shadows. Observational data of the Sagittarius A* (Sgr A*) shadow released by the Event Horizon Telescope (EHT) are used to investigate eventual deviations in the black hole shadow radius, aiming to seek physics beyond the Standard Model (SM) coming from extra-dimensional theory. We consider the brane ...
Há 4 dias · Embora os discos em torno de buracos negros supermassivos já tenham sido fotografados anteriormente - o EHT (Event Horizon Telescope) fotografou discos em torno de buracos negros no coração da nossa própria Galáxia em 2022 e em Messier 87 em 2019 - estes discos estão muito mais próximos e são mais calmos do que os existentes em torno dos quasares.
Há 1 dia · The Very Large Telescope Interferometer gathers infrared light. That array is also based in Chile. And then there is the Navy Precision Optical Interferometer in Arizona. That array observes the universe in visible light. In a sentence. The Event Horizon Telescope used very long baseline interferometry to create the first image of a black hole.
Há 4 dias · Black hole science took a big step in 2019 when the Event Horizon Telescope captured the first image of a black hole. That SMBH was in Messier 87, a supergiant elliptical galaxy over 50 million ...
Há 4 dias · A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organised magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*).
Há 4 dias · The Event Horizon Telescope has recently provided the first image of the dark shadow around the supermassive black hole M87*. The observation of a highly circular shadow provides strong limits on ...
