A team of scientists discovered the situation that occurs when destroying Giant star Upon entering a black hole, a new study sheds light on super-energy cosmic rays.

Researchers affiliated with more than 20 international institutions, including New York University and the German DESY Research Center, have studied one of the smallest elements in the universe, a “neutrino” (a neutrino is an elementary particle with a mass much smaller than the mass of an electron, and it has no electrical charge), which are subatomic particles that are produced. On Earth, only at very tremendous speeds.

Researchers and scientists have discovered the existence of a high-energy neutrino resulting from the destruction of the star when it approaches the black hole, in a discovery that sheds light on the origins of the super-energy cosmic rays, which are the highest energy particles in the universe, according to the research published in the journal “Nature Astronomy”, a specialized scientific journal.

“The origin of high-energy cosmic neutrinos is unknown, mainly due to the difficulty of identifying them,” says scientist Seger van Velzen, one of the lead authors of the research and a postdoctoral fellow in the Department of Physics at New York University, commenting on the discovery. In it, high-energy neutrinos are returned to their source.

Previous research by Van Velzen, now at Leiden University in the Netherlands, and New York University physicist Glennis Farrar, co-author of the paper, found some of the earliest evidence of black holes destroying stars in what is now known as “tidal disturbance events” (TDEs). ), As this process was responsible for the production of these neutrinos.

The new published research provided confirmation of the accuracy of this information. Specifically, its measurements showed the spatial coincidence of a high-energy neutrino and the light emitted after the destruction of a black hole (consuming a black hole of the star) of a giant star.

“The discovery of neutrinos associated with TDEs (the consumption of black holes of stars) is a breakthrough in the understanding of the origin of high-energy astrophysical neutrinos,” said the research, which was shared by the specialized scientific journal “scitechdaily”.

Scientists confirm that “monitoring the presence of neutrinos in this process also sheds light on a decades-old problem, which is the source and origin of the ultra-high-energy cosmic rays.”
