Capturing the accretion flow of M87* black hole

22 January 2025

Six years after the publication of the historic image of the supermassive black hole M87*, the first capturing a black hole, the Event Horizon Telescope (EHT) Collaboration unveils a new analysis of M87*. This analysis combines observations made in 2017 and 2018 and provides new insights into the structure and dynamics of the plasma near the edge of the black hole. In particular, the results, published in Astronomy & Astrophysics, confirm that the rotation axis of the black hole M87* points away from Earth, and demonstrate that turbulence within the accretion disk – the gas rotating around the black hole – plays an important role in shifting the peak brightness of the ring. The data analysis allowed us to accurately interpret the observations of 2017 and 2018, and to compile a library of about 120,000 simulation images that will open up new theoretical predictions on some of the most mysterious phenomena in the universe.

Immagine di buco nero mmagini osservate e teoriche di M87*. I pannelli di sinistra mostrano immagini di M87* provenienti dalle campagne osservative di EHT del 2017 e del 2018. I pannelli centrali mostrano immagini esemplificative di una simulazione magnetoidrodinamica relativistica generale (GRMHD) in due momenti diversi. I pannelli di destra presentano le stesse istantanee della simulazione, sfocate per adattarsi alla risoluzione osservativa di EHT. Crediti: EHT Collaboration.
