Scientists discover a rare type of black hole that kills a star. Intermediate mass black holes are considered the rarest of all black holes.
They are much heavier than a star, but not as massive as stars at the centers of galaxies. These black holes have only been identified a few times.
Now, an intermediate-mass black hole has been discovered thanks to its terrible actions: tearing apart a star in a distant dwarf galaxy wandering nearby, in an event that astronomers’ literature calls Tidal Disturbance Event (TDE)depending on the page Space. com .

TDE makes itself visible by emitting a burst of radiation so powerful that it surpasses all the stars combined in its dwarf galactic home. This TDE could help scientists better understand the relationship between galaxies and the black holes they contain.
The research team has reason to believe that this event received a symbol “See you 2020neh” – is the destruction of a star by a black hole.
By modeling the event, it is estimated that this black hole has a mass of 50,000 to 800,000 times that of the Sun. In comparison, black holes emit gravitational waves, often tens of times more massive than the Sun. Supermassive black holes at the centers of galaxies can reach millions or even billions of times the mass of the Sun.
The first author to discover the event, Charlotte Angus of the Niels Bohr Research Institute (Denmark), said: “In fact, we captured this intermediate black hole as it swallowed a star.”
Additionally, researchers can use the properties of the flare itself to better understand this elusive group of intermediate-mass black holes. They could make up the majority of black holes at the centers of galaxies.
According to the page IFLScience supermassive black holes existed very early in the universe – too early for them to make sense in many theories.
One possibility is that the formation of supermassive black holes comes from the merger of many intermediate-mass black holes.
Co-author Vivienne Baldassare, professor of physics and astronomy at Washington State University (US), said: “One of the biggest open questions in astronomy today is how supermassive black holes form.”
Professor Enrico Ramirez-Ruiz – an astronomer and astrophysicist at the University of California – explains: “If we can understand the population of intermediate-mass black holes – how many there are and where they are – it could help us determine whether the theory of supermassive black hole formation is correct.”.
