Cosmic Ray Electron Propagation
Cosmic Ray Nucleon Transport
Spectral Index Modelling ndash NGC 891 amp NGC 253
Diffuse γ-Ray Modelling
Cosmic rays were first determined to be coming from outer
space when hellip
a sharp increase in cosmic rays was observed when ET was released in 1982
Michelson amp Morley performed their famous experiment in 1887 determining that there was no
ether surrounding the earth
Viktor Hess in 1912 carried ionization chambers to high altitudes and detected an increase in
radiation as he ascended
August 7th
1912
The project based in Utah amp Argentina that when completed will be the
largest cosmic ray detection array ever built is known as hellip
the Blair Witch project
the Manhattan project
Pierre Auger project
The highest ever detected energy of a cosmic ray is hellip
