Independent Study Validates Black Hole Image
Confirmed
In Short: An independent team has confirmed the original image of a black hole's shadow using a new machine learning algorithm.
An independent group of researchers has now reanalyzed the EHT data, publishing their findings in Nature on November 11.
Their results largely corroborate the original findings, including new images of the black hole.
Some researchers previously argued that the circular shape in the original image was an artifact of the team's image-reconstruction techniques.
To image black holes, the EHT collaboration combines data from an array of ground-based radio telescopes spanning several continents.
The independent team used a new machine learning algorithm to analyze the same base data.
The reconstruction process is extremely challenging, but the result is an image with the same level of detail as if it were taken with a single radio dish as wide as Earth.
