Scientist superstar Katie Bouman developed an algorithm for the image of a black hole

US computer scientist Katie Bouman, who was unveiled to the public a few days ago, has become a sensation with her role in developing a computer algorithm that has allowed researchers to capture the world's first image of a black hole.

"I'm so excited we can finally announce what we've worked on over the last year!" The 29-year-old Bouman, a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics, gushed on Wednesday after the image appeared compressed on her Facebook account that it creates a gravitational field from which even light can not escape. The massive black hole in the photo published Wednesday is 50 million light-years away at the center of a galaxy known as the M87.

While the existence of black holes has long been known, the phenomenon could not be detected.

In 201

6, Bouman developed an algorithm called CHIRP to scour a real mountain of data collected by the Event Horizon Telescope project from telescopes around the world to create an image. was located in a mountain of several hundred pounds of computer hard drives that had to be physically transported to the Haystack Observatory in Westford, Massachusetts, operated by the Massachusetts Institute of Technology (MIT).


To ensure the accuracy of the image, the Harvard-Smithsonian Astrophysics Center, operated by Harvard University, passed the data on to four different teams. Each team used the algorithm independently to get an image.

After a month of work, the four groups presented their results to the other teams.

"That was the happiest moment I ever had. [when] I saw that all the other teams had very similar pictures, with the bottom half brighter than the top half." It was amazing to see that everyone understood that "said Bouman to the Wall Street Journal.

Work as assistant professor at the California Institute of Technology (Cal Tech).

"It took the amazing talent of a team of scientists from all over the world and years of hard work to create the instrument, data processing, imaging methods, and analysis techniques necessary to make this seemingly impossible performance," she said on Facebook.

"It was truly an honor and I am so happy that I had the opportunity to work with you all."
