Researchers have revealed the origin of neutrinos, elementary particles that reach our planet from deep within the universe.
There is a constant bombardment of cosmic rays bombarding our planet's atmosphere daily. They consist of electrically charged particles with extremely high energies - up to 1020 electron volts in some cases.
It should be noted that this is a million times more energy than that achieved by CERN's Large Hadron Collider near Geneva, the world's most powerful particle accelerator, which is the world's most powerful particle accelerator.
As well as coming from deep outer space, these incredibly energetic particles have traveled billions of light years across the galaxy. Where do they come from, what sends them into space with such tremendous force, and where do they go when they get there? There is no doubt that these questions have remained among the greatest challenges of astrophysics for over a century now.
During the birth of cosmic rays, neutrinos are produced at their birthplaces. It is very difficult to detect these neutral particles because they are so small. As a result, they have almost no mass and barely interact with any matter at all.
There are many types of worms that race through the Universe and can travel right through galaxies, planets, and even the human body almost without leaving any trace behind.
There is no question that astrophysical neutrinos are produced by processes involving cosmic ray acceleration, as explained by astrophysics professor Sara Buson of Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany.
The unique properties of neutrinos are exactly what makes them such valuable messengers, serving as a means for pinpointing cosmic ray sources as a result.
The neutrino. It is evident that despite the vast amount of data that astrophysicists have collected, the issue of how high-energy neutrinos are associated with the astrophysical sources from which they originate has remained unsolved for many years. As far as Sara Buson is concerned, it has always been a major challenge for her.
It was in the journal Science in 2017 that the researcher and his collaborators for the first time brought a blazar (TXS 0506+056) into the discussion as a potential neutrino source.
Blazars are active galactic nuclei powered by supermassive black holes that emit a much greater amount of radiation than the entire galaxy they are part of. This publication has sparked a scientific debate concerning whether or not there is indeed a connection between blazars and high-energy neutrinos as a result of the publication.
