With communication of n NASA reports that space and ground-based telescopes have spotted a supersized black hole which, after devouring a star, increased its volume and is now trying to trap a second space body located in the same region, as scientists studying the phenomenon have not yet determined whether it is another star or a small black hole.
The discovery, among other things, provides information about the environment that exists around some of the largest types of black holes.
In 2019, an optical telescope in California observed a burst of light that astronomers later categorized as a “tidal disruption event,” or TDE. These are cases in which black holes capture stars in their gravitational networks that literally disintegrate with their matter falling into the black hole, producing various cosmic phenomena that start from the increase in the mass of the black hole and end with a launch of tremendous power, speed and luminosity of jets. of matter and energy. Astronomers named this TDE AT2019qiz.
The combination
Meanwhile, scientists were also observing another type of cosmic phenomenon that is occasionally observed throughout the Universe. These are frequent but short bursts of X-rays found near supermassive black holes. Astronomers called these events “quasi-periodic bursts,” or QPEs.
The new findings give scientists evidence that TDEs and QPEs are likely linked. Researchers believe that QPEs occur when an object invades the disk left behind after TDE. While there may be other explanations, the study authors suggest this is the source of at least some QPE.
