Original image of M87* supermassive black hole and new enhanced version
A side-by-side comparison shows the original image (left) of the M87* supermassive black hole published by the Event Horizon Telescope collaboration in 2019, and a new image (right) generated with the PRIMO algorithm using the same data set. The PRIMO algorithm was developed by a team of researchers, including an astronomer with NSF’s NOIRLab, to enhance the fidelity and sharpness of the radio interferometry images.
[NOIRLab is supported by the U.S. National Science Foundation.]
