What do you call a group of black holes ... a flock, a brace, a swarm? Monitoring a region around the center of our Galaxy, astronomers have indeed found evidence for a surprisingly large number of variable x-ray sources - likely black holes or neutron stars in binary star systems - swarming around the Milky Way's own central supermassive black hole. Chandra Observatory combined x-ray image data from their monitoring program is shown above, with four variable sources circled and labeled A-D. While four sources may not make a swarm, these all lie within only three light-years of the central supermassive black hole known as Sgr A* (the bright source just above C). Their detection implies that a much larger concentration of black hole systems is present. Repeated gravitational interactions with other stars are thought to cause the black hole systems to spiral inward toward the Galactic Center region.
해석좀 해주세요..저게 블랙홀다발이란 건가요??

블랙홀이 물질을 빨아들일 때에는 강한 X선을 방출한다고 하는데, 그 X선 방출점을 중심으로
재구성된 이미지인 듯 합니다. '이진수 시스템(?)'등 몇가지 용어가 의미하는 것을 알 수 없어
문장내용을 끌어올 수 없네요. 혹, 다른 도움이 될 지 모르니 아래 주소도 참고하시기 바랍니다.
