Cosmic rays, consisting of high-energy and electrically charged particles, continuously bombard the Earth’s atmosphere.
These particles come from outer space and have traveled billions of light years. However, where do they come from? What is shooting them across the universe with such tremendous force? These questions have been among the most difficult problems in astrophysics for over a century.
An international research group led by the University of Würzburg and University of Geneva (UNIGE), sheds light on one aspect of this mystery: it is believed that neutrinos are born in blazars Galactic cores are powered by supermassive black holes.
In 2017, Sara Buson and other researchers suggested that the blazar TXS 0506+056 could be a potential source of neutrinos.
This study sparked scientific debate about whether there really is a connection between blazars and high-energy neutrinos.
With this first step, Buson’s team received funding from the European Research Council to launch an ambitious research project in June 2021. Technical Researcher.
It is necessary to analyze numerous signals (or “messengers”, for example, neutrinos) from the Universe. The main goal is to understand the origin of astrophysical neutrinos, confirming whether blazars are indeed the first highly reliable source. high-energy extragalactic neutrinos.
Now the project has achieved its first success. Scientists have confirmed that blazars can be confidently associated with astrophysical neutrinos with an unprecedented degree of confidence, according to a new study. published no American Astronomical Society,
“The process of accretion and the rotation of a black hole lead to the formation of relativistic jets, where particles are accelerated and emit radiation up to a thousand trillion energies of visible light. The discovery of a link between these objects and cosmic rays could be The “Rosetta Stone” of astrophysicists high energy,” said Andrea Tramacere from the University of Geneva.
Scientists used neutrino data from the IceCube neutrino observatory in Antarctica and BZCat, one of the most accurate catalogs of blazars.
Using this data, they had to prove that the blazars, whose position in the direction coincides with the position of the neutrino, did not appear by chance.
So, developed software is able to estimate how similar the distributions of these objects in the sky are.
“After we rolled the dice a few times, we found that a random association can only outperform a true association once in a million trials. This is strong evidence that our associations are correct,” emphasizes Tramacere.
Despite the results of the study, the research team believes that the number of results in this initial sample just the tip of the iceberg.
Through their efforts, they have collected “new observational data,” a key ingredient in building more accurate models of astrophysical accelerators.
“What we need to do now is understand the basic difference between objects that emit neutrinos and those that do not. This will help us understand how much the environment and the accelerator “talk” to each other,” the team emphasizes.
“Then we can abandon some models, improve the predictive power of others, and finally add more pieces to the eternal puzzle from the acceleration of cosmic rays,” the researchers concluded.

Android 13 is already a reality and Google smartphone users can install this version. This is still a short list, but it opens the door for other manufacturers to use.
Now that it is available, reports are starting to appear that are not positive. Everything points to problems using various applications, including banking.
Are much news which Google has invested in Android 13, in particular, to protect users and their data. They have been introduced in various test versions released and have finally reached maturity in the latest submitted version.
This new system, still limited to Google Pixels, is gradually moving to smartphones. It's still a small audience, but it lets us know how it will behave in the future. Unfortunately, the news in this area is not the best.
Many reports point to problems using various applications on this new Google system. They seem to have compatibility issues and don't work properly for android system users.
The solution that seems to exist is just waiting for new versions of those apps to come out. Developers should check the issues and release updates to Android 13 versions of their apps with issues within a few days to resolve the issue.
If in previous years one of the solutions could be to return to the previous version of the Google system, then this is no longer possible. One of the measures taken just prevents the regression of the version by blocking the smartphone in the latest version.
This is bad news for Android 13 and for Google, although it's only for developers. All applications should be updated in the coming days, which will allow you to receive support for the new version and fix the problems found once and for all.
