The black hole is located a million light years away in a dwarf galaxy.
When an ominous star wandered too close to an intermediate-mass black hole hidden in a dwarf galaxy, it revealed itself to astronomers, according to a new study published in the journal Science. Nature Astronomy.
The exploration allowed the calculation of the black hole’s mass. It could also help researchers better understand how black holes and galaxies interact.
According to the study published in online magazine, Giant black holes (BHs) are ubiquitous at the centers of massive galaxies. On the other hand, the population of BHs within dwarf galaxies is not yet known. Dwarf galaxies are thought to harbor a proportionally small mass BH, including intermediate-mass black holes.
The report further states, “The identification of these systems has historically relied on the detection of light emanating from the gaseous disk close to the BH. Without this light, they are difficult to detect.”
According to science daily, The star clipping, known as a “tidal disintegration event” or TDE, produced a flash of radiation that briefly strips away the combined stellar light of the host dwarf galaxy and allows scientists to better understand the relationship between black holes and galaxies. It can help in understanding.
“This discovery has generated widespread excitement because we can use tidal disruption events not only to find more intermediate-mass black holes in cool dwarf galaxies, but also to measure their mass, said co-author Ryan Foley, assistant professor of astronomy and astrophysics. UC Santa Cruz who helped plan the YSE survey.
First author Charlotte Angus of the Niels Bohr Institute said the team’s findings provide a baseline for future studies of midsize black holes.
