Using PSC’s Bridges-2 system to simulate signals in their Antarctic IceCube detector, an international collaboration of scientists has now made the first map of the Milky Way galaxy using particles called neutrinos — the first map of a cosmic structure that didn’t depend on electromagnetic waves.
Lots of neutrino detectors work similarly, with giant vats of liquid (sometimes water something something more reactive with neutrinos), IceCube uses natural ice so it can be much larger than fully constructed observatories. It also looks for very high energy neutrinos which makes the job a little easier, one of the big difficulties with neutrino observatories is filtering out interference...
IceCube scientists and engineers assembled digital optical modules (DMOs) - instruments the size of basketballs - and installed them at depths of up to two kilometers under the ice.
The IceCube group at Humboldt University is involved in searches for point-like sources of cosmic high-energy neutrino emission and participates in the development of efficient neutrino reconstruction techniques. Additionally, we are working on modeling of cosmic sources as to the expected neutrino flux from these sources.
Easy text A+ A++ 🌙 8 min Ice Cube, the frozen observatoryDeep in the ice below the Amundsen-Scott South Pole Station, in Antartica, lies one of the great works that our modern civilization has produced. A kilometer and a half under the frozen surface there is a very special place for science and discovery. Darkness […]
IceCube is an array of optical sensors located in Antarctic ice. It detects the presence of subatomic particles called neutrinos.
