Scientists have discovered several new potential sources of neutrino – elementary particles, the sources of origin of which scientists still have not been able to establish. This is stated in a study by scientists from the IceCube mission, which leads phys.org.
Neutrinos are neutral elementary particles, which account for up to half the composition of cosmic rays. Such particles constantly bombard the Earth – every second through 2.5 square meters. cm man passes up to 100 billion neutrinos.
The IceCube Observatory is located at a depth of about 2 km at the South Pole. At this depth, ice does not form air bubbles that distort the data on the neutrino trajectory.
The station is a neutrino detector with an area of about 1 cubic meter. km, which is equipped with 56 “strings” and 5.2 thousand optical sensors. Particles pass along the strings, and optical sensors try to detect a weak blue glow of muons – particles that are formed as a result of neutron collisions with ice atoms and emit a weak blue glow.
Scientists have been trying to find a source of neutrinos for 10 years – now, probably, the researchers managed to do this. During a scan of the entire sky, the researchers discovered very bright flashes of neutrinos, and then mapped these arbitrary neutrino sources by overlaying the data on a map of the starry sky.
Further study of the data allows us to more accurately determine the location of neutrino sources, the study said.
