Interesting new way of looking at things.

thx .

They don't really say what we are looking at. The energies are absurdly high (1M electron masses) so it's not from regular stars like the sun (less than 1 MeV). Neutron stars, black holes, gamma ray bursts, quasars?

Hi Henk. The article states that they are looking at Cherenkov radiation created by high energy neutrino interactions in the ice, which have been traced as coming from our galaxy by their interaction type. The image shows areas of our galaxy producing high-energy neutrinos, albeit with relatively low resolution. The image is created using Cherenkov radiation to map neutrino density distribution along the plane of the milky way. A kinda blue light neutrino density image.

This neutrino distribution profile closely corresponds with gamma-ray images of our galaxy. Why is this important? When cosmic rays, created from high energy or cataclysmic events in our galaxy, collide with matter, like gas and such, in our galaxy, they should produce both gamma rays and neutrinos. Gamma-ray images have already been produced, but this neutrino imaging technique would seem to link the two from the same process. Determining precisely what caused the chain in the first place, like where the cosmic rays came from that created the neutrinos that produced the Cherenkov radiation that we detect, is extremely difficult. So, for now, one can't say exactly what produced the cosmic rays that produced the neutrinos. However, Once detector technology advances and the number of detectors increases, along with machine learning algorithms, the resolution will increase, and then we'll have a better understanding of where they are coming from, perhaps unveiling hidden features of our galaxy.
