Sentences with phrase «detected by cosmic ray»

UHECRS, very high energy protons and charged nuclei, occasionally arrive on Earth, where they are detected by cosmic ray detectors such as the Pierre Auger Observatory in Argentina.

Not exact matches

The renowned British physicist Paul Dirac first posited the existence of antimatter in 1928, and four years later researchers at Caltech detected the first documented antiparticles — positrons produced by the impact of cosmic rays on the atmosphere.

Over time, it should detect tens or hundreds of cosmic rays from individual AGNs and their range of energies should clarify exactly how they were accelerated — a process thought to be controlled by magnetic fields around the colossal black holes.

It does so by detecting the gamma rays those elements emit when they are bombarded by high - energy charged particles from space called cosmic rays.

By detecting the faint fluorescence and the particles that reach the ground, Auger should be able to pin down the energy and direction of the original cosmic ray.

The EUSO telescope, which will be used to find debris, was originally planned to detect ultraviolet light emitted from air showers produced by ultra-high energy cosmic rays entering the atmosphere at night.

The high - energy cosmic neutrinos detected by IceCube are believed to originate from cosmic - ray interactions with matter (proton - proton interactions); from cosmic - ray interactions with radiation (proton - photon interactions); or from the decay or destruction of heavy, invisible «dark matter.»

The idea is to detect neutrinos produced by interactions between cosmic rays and Earth's atmosphere.

It covers an area of 3000 square kilometers with approximately 1600 surface detector stations which detect cosmic ray shower particles directly, as well as four fluorescence detectors which overlook the atmosphere above the surface array and detect fluorescence light emitted by shower particles.

The Pierre Auger Observatory has detected more muons from cosmic - ray showers than predicted by the most up - to - date particle - physics models.

Such a telescope would use large arrays of ground - based telescopes to detect blue flashes of Cerenkov radiation, which are caused by very high energy gamma - ray photons from cosmic sources smashing into the atmosphere.

The array is slated to be so much larger than Auger South because the highest energy cosmic rays are only detected by Auger South twice a month.

During periods of heightened solar activity, fewer galactic cosmic rays (GCRs) are detected by earthbound neutron monitors.
