Guwahati Mar23:Rongmon Bordoloi, an Indian scientist who hails from Assam, has become the first person to figure when did the black hole in the galaxy "last big meal" took place. He is now leading a team at Massachusetts Institute of Technology (MIT) who found that the black hole "ate its last big meal about 6 million years ago, when it consumed a large clump of infalling gas."
"For the first time, we have traced the motion of cool gas throughout one of the bubbles, which allowed us to map the velocity of the gas and calculate when the bubbles formed. What we find is that a very strong, energetic event happened 6 million to 9 million years ago. It may have been a cloud of gas flowing into the black hole, which fired off jets of matter, forming the twin lobes of hot gas seen in X-ray and gamma-ray observations." said Bordoloi
Bordoloi added that "Ever since then, the black hole has just been eating snacks."
