Scientists uncover the origin of neutrinos for the first time

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.

Being very close companies, OPPO and OnePlus have decided to create a new partnership, with the latter being a pioneer in the market. It has become the representative of the best smartphones in the group, and this will be seen very soon.
Proving this, OnePlus has announced that it will have news soon. The following brand assets will be announced on February 7, 2023. We are talking about OnePlus 11 5G and Buds Pro 2.
In recent years, OnePlus has been showcasing new hardware in an attempt to find a new place in the market. The brand has not always seen its full potential, betting on mid-range or entry-level smartphones.
The situation is changing, and the novelty will go on sale in early 2023, February 7. It is on this day that the new OnePlus 11 5G will be presented with all the expected news. We definitely have the new Qualcomm Snapdragon 8 Gen 2 SoC here. There's still 16GB of storage left and 256GB of onboard storage.
It is expected that he will receive a 6.7-inch OLED display with a resolution of 1440p and a frequency of 120 Hz. In the field of photography, we will have an important change: a 50 MP main camera, a 48 MP ultra wide-angle camera and a 32 MP telephoto lens with 2x zoom. For selfies and video calls, you'll have a 16-megapixel camera.
The photography partnership with Hasselblad will continue with OnePlus for fine-tuning and some additions. This alliance has brought important results for the best smartphones of the brand, guaranteeing the best photos in any situation.
In addition to the new OnePlus 11 5G, another brand new feature is also expected to arrive at the event. We're talking about the Buds Pro 2, which are solidifying an audio commitment that's becoming more of a reality. The brand promises "rich stereo quality sound with crystal clear clarity".
Stays like this marked by the beginning of February, another important novelty will enter the market. OnePlus wants to reclaim its place, and that will be the brand's bet for years to come. OnePlus 11 5G and Buds Pro 2 take the first step in this direction.

According to information provided by Mukul Sharma, the unidentified POCO device can be identified by the model number 22127PC95I. Due to the fact that it was first seen online, the marketing name of this equipment is still a mystery.
POCO has not launched new mobile devices, including smartphones, to the market for some time now. On the other hand, several POCO smartphones such as POKO X5 and X5 Pro have been spotted on various certification sites, suggesting that the company will release these products soon. Today a new smartphone from the sub-brand xiaomi has been spotted on the BIS India website but the device does not have a name or any other details associated with it.

According to information provided by Mukul Sharma, the unidentified POCO device can be identified by the model number 22127PC95I. Due to the fact that it was first seen online, the marketing name of this equipment is still a mystery. It is possible that it will debut as a mid-range smartphone. The Bureau of Indian Standards (BIS) website, other than the model number of the smartphone, does not provide any additional information about the device. However, this seems to indicate that the product will be available in the Indian market very soon.
In other related news, POCO X5 5G has recently been seen on several certification sites including SIRIM in Malaysia, BIS in India and the US FCC. According to various sources, it is possible that this is a renamed or modified version Redmi Note 12 5Gwhich was recently released in China.
It is supposed to be equipped screen 6.67″ AMOLED display with 120Hz refresh rate and chipset Snapdragon 4 Gen 1 inside. Can run MIUI 13 based on android 12 and have LPDDR4x RAM in addition to UFS 2.2 storage. The front camera is rumored to be 8MP while the main rear camera will be 48MP with 2MP depth. May have the ability drums 5000 mAh and 33W fast charging support.
In addition POCO X5 Pro 5G has recently been seen on various sites dedicated to certification. The battery is said to have a capacity of 5000 mAh and can charge at 67W. It will come with MIUI 14 preinstalled and will support n5, n7, n38, n41, n77 and n78 network bands. 5G.
