Without this light, they are difficult to detect.ĭata from the Young Supernova Experiment enabled the team to detect the first signs of light as the black hole began to eat the star. Identification of these systems has historically relied on the detection of light emitted from accreting gaseous disks close to the black holes. “This discovery has created widespread excitement because we can use tidal disruption events not only to find more medium-mass black holes in quiet dwarf galaxies, but also to measure their masses.”Ryan Foleyĭwarf galaxies are thought to harbor black holes with proportionally small masses, including medium-mass ones, like in this case. “This discovery has created widespread excitement because we can use tidal disruption events not only to find more medium-mass black holes in quiet dwarf galaxies, but also to measure their masses,” said coauthor Ryan Foley, an assistant professor of astronomy and astrophysics at UC Santa Cruz who helped plan the YSE survey. The shredding of the star, known as a “tidal disruption event” or TDE, produced a flare of radiation that briefly outshone the combined stellar light of the host dwarf galaxy and could help scientists better understand the relationships between galaxies and black holes. “This flare was incredibly fast, but because our YSE data gave us so much early information about the event, we were really able to pin down the mass of the black hole using it,” First author Charlotte Angus said. The galactic outburst was captured by astronomers with the Young Supernova Experiment (YSE), a survey designed to detect cosmic explosions and transient astrophysical events.Īn international team led by scientists at UC Santa Cruz, the Niels Bohr Institute at the University of Copenhagen, and Washington State University reported the discovery in a peer-reviewed paper published in Nature Astronomy.
