  1. Arnold Wolfendale, Durham University, UK KGF and ICE-CUBE neutrinos

  2. Airy’s Commemorative seal Airy’s commemorative seal (design by James Basire, 1796 – 1869)

  3. KGF Group, 1965 KGF group, 1965 (7600ft. underground)

  4. CR Muon

  5. A neutrino event

  6. A ‘golden event’

  7. ICE-CUBE From Francis Halzen Right: Surface view of the full IceCube (IC86) detector layout. Filled marks represent the x-y positions of the IceCube strings. Red marks in the central region are the DeepCore strings. Squares represent the strings that did not exist in the IC79 configuration. Open circles are the positions of the closest strings to the observed two cascade events. Stars are the reconstructed vertex positions of the two cascade events.

  8. Bert Ernie The two observed events from August 2011 (left panel) and January 2012 (right panel). Each sphere represents a DOM. Colors represent the arrival times of the photons where red indicates early and blue late times. The size of the spheres is a measure for the recorded number of photoelectrons.
