"The role of black holes in galaxy evolution is an outstanding question in modern astrophysics. As Erin Kara, assistant professor of physics at MIT, said: The scientists believe that these findings can help explain how supermassive black holes at the center of galaxies can help shape their formation. After one last high-energy flash when the corona and jet die out, the black hole enters a "soft," low-energy state. So what did the team find out by analyzing the echoes? They found that the black holes initially go through a "hard" state upon feeding, wherein it forms a corona of high-energy photons and launches a jet of high-energy particles close to the speed of light. Ten of them are close enough for the echoes to be observable, and eight were previously not known to emit echoes. Their algorithm identified 26 black hole X-ray binary systems, which are systems with a star that's being consumed by a black hole at times. #Trying to make a video about a star going into a black hole update#Update your settings here, then reload the page to see it.įor their new study, the astronomers developed an automated search tool called "Reverberation Machine" to comb through data gathered by NASA's Neutron star Interior Composition Explorer, the X-ray telescope aboard the ISS.
