Astronomers have found evidence of a black hole snacking on a star in data gathered back in the 1980s, according to new research.
8 ways we know that black holes really do exist
Ravi and a team of scientists discovered the signature of a tidal disruption event in archival observations flagged by interns Ginevra Zaccagnini and Jackson Codd. The teens were reviewing data gathered by the National Radio Astronomy Observatory's Karl G. Jansky in New Mexico and noticed that a particularly bright signal seen in the mid-1990s had faded by 2017.
The team began looking for other observations of the object, dubbed J1533+2727, and found that the Green Bank Observatory's 300-foot radio telescope had spotted the same object beforein 1988. In fact, Green Bank's observations from 1986 and 1987 showed the object appearing even brighter than in the 1990s data the researchers had started with. All told, the researchers said, the object is now 500 times dimmer than it was at its brightest.
In their analysis of the event, the scientists concluded that the bright flash was likely caused by a supermassive black hole 500 millionThe researchers hope that the event and others like it will help them better understand tidal disruption events , the black holes that cause them and the galaxies in which these black holes reside.
"Interestingly, neither of the radio-discovered candidates were found in the type of galaxy most popular for TDEs," Hannah Dykaar, a PhD student in the department of astronomy and astrophysics at the University of Toronto and a co-author on the new research, said in the same statement."Finding more of these radio TDEs could help us to illuminate ongoing mysteries about what types of galaxies they occur in and just how many there are in the universe.
