"The Glorious Past of Our Monster Black Hole"

The supermassive black hole in the center of our galaxy, known as Sagittarius A*, is one of the least luminous known supermassive black holes of the Universe. While recent observations show that it flares up moderately from time to time, it is a mystery whether the monster black hole was more active in the past. Although we cannot directly see its past activities, a glorious past of our galaxy's black hole has been revealed by gas clouds in the central region of the Galaxy.
