AI improves black hole images

The image on the left is the one presented in 2019 based on data recorded by the Event Horizon Telescope array. On the right, we see a processing based on the same original data by an artificial intelligence algorithm called PRIMO, trained on a series of realistic simulations of black holes with accretion disks.

PRIMO is a new application of artificial intelligence (AI) in astronomy that enhances the resolution of black hole images

A rapidly growing black hole

This Arp 299 system consists of a pair of galaxies, IC 694 and NGC 3690, which underwent a close encounter about 700 million years ago. As a result of this interaction, the system underwent a fierce burst of star formation. In the past fifteen years or so, six supernovae have exploded in the outermost regions of the galaxy, making this system a prominent supernova factory. Credit: NASA

Astronomers have discovered a rapidly growing black hole in one of the most well-known galaxies in the primordial universe

Event Horizon targets the Centaurus A radiogalaxy

The Event Horizon Telescope (EHT) aims at the heart of Centaurus A radio galaxy, providing a detailed image of its black hole jets.
