Without a public name one day ago, a US scientist lesson named Katie Bouman has become overnight because of his role in the development of a computer algorithm that enabled first image researchers of black holes. build.

"I'm so excited that we eventually get what we were doing in the last year!" the 29-year-old Bouman, a postdoctoral researcher in the Harvard-Smithsonian Astrophysics Center, was poured onto his Facebook account on Wednesday after the image was published. compression that creates a gravity field that light can not even escape from it. The huge black hole in the photograph is released Wednesday 50 million years ago at the heart of a galaxy called M87.

Although black holes were known to exist, it was impossible to witness the phenomenon.

6, Bouman developed an algorithm called CHIRP to flow through real-life data collected by the Event Horizon Telescope project from telescopes around the world to create an image.

was in a mountain of computer hard drives which had a few hundred pounds in them which would be physically transported to the Haystack Observatory in Westford, Massachusetts, operated by Massachusetts Institute of Technology (MIT).


To guarantee the accuracy of the image, the Harvard-Smithsonian Astrophysics Center, operated by Harvard University, provided the data for four different teams. Each team used the algorithm independently to get image.

After a month's work, the four groups presented their findings to the other teams.

"That was the happiest moment I ever had [when] I saw that all the other teams had very similar images, with the half brighter than the upper half. It was great to see that everyone said that, "Bouman told the Wall Street Journal.

"No algorithm or one person did this image," wrote Bouman, who will start falling working as an assistant professor in California Institute of Technology (Cal Tech).

“He wanted a wonderful talent team of scientists from all over the world and years of hard work to develop the instrument methods, data processing, imaging, and analysis techniques needed to make this impossible,” he said. she said on Facebook.

"It was a great honor for me, and I am lucky that I had the opportunity to work with you all. "
