Black holes in imagery worked Haystack Observatory in Westford – News – Lincoln Journal


When the news of the first image of a black hole M87 hit the news earlier this month, it may seem a galaxy far away, but in fact, researchers have spent years working on the photos directly in Westford.

Scientists at the MIT Haystack Observatory have the level of spending decades working to capture an image of a black hole located in the center of the galaxy M87 and the revealing image captured by space enthusiasts around the world.

But little do people know that a large part of the work carried out by imaging passed so close to home.

Before the image of Sagittarius A, the supermassive black hole space of more than 26,000 light-years from Earth, being published Wednesday, April 10, scientists have created an image with the Event Horizon Telescope Collaboration (EHT,) and a collection of telescopes around the world.

What they made was the discovery of time-in-life-time for groups of researchers involved: orange image glowing rings that stand out clearly against the background of a bewildering, black background space.

Stack group includes Dr. Kazunori Akiyama and Dr. Vincent fish. The pair, along with other researchers working on the project within the white dome of the observatory on Millstone Road. Observatory dates back to 1960.

Kazunori, who is originally from Japan and earned a degree in Tokyo in the late 2000s, was one of the main developers of visualization software used in the capture of Sagittarius A. He said that he came to Rick in 2015, and was thrilled to work that he called two of the "power" of observation places on the East coast of the United States of America and Japan.

Kazunori called it "strange" to see these images for the first time. He said that it was hard to sleep the night before the visuals have been identified in the scientific community in the past year.

The fish, which is working on a project with one of the four teams in the EHT field for the past 12 years, said Rick works with the use of technology with a very long baseline interferometry (VLBI) for more than 50 years. This method of data collection, several telescopes, such as those used to capture an image of a black hole, can put together a common visual, as if the researchers used a telescope.

"It was a lot of work that went into it," said Fish. "Once you have noticed that when the tough part is actually going on."

This advance will help in their work of general relativity prediction test, which is described as a fish material in space, fed into a black hole, and it becomes very hot, resulting in a glowing ring structure.

"It was really good to confirm that the forecast," said Fish. "For the M87, if you took it for granted one of the two massive power ratings, our measurement of the diameter of the ring is actually a test of general relativity. GR tells you how wide that the ring should be. "
