WebHá 1 dia · Astronomers detect FIVE new fast radio bursts from over 4 billion light years away. Fast radio bursts are intense radio waves that typically last for a few milliseconds. … WebThis radiation is detected by the photomultiplier tubes and shows up as a characteristic ring-like pattern of activity in the array of photomultiplier tubes. As neutrinos can interact with atomic nuclei to produce charged leptons which emit Cherenkov radiation, this pattern can be used to infer direction, energy, and (sometimes) flavor information about incident …
