The students will be challenged to look for answers to this question by analyzing data of the Pierre Auger Observatory. The measurement includes:

  • Visualization of events using an interactive display of the observatory
  • Separation of surface-detector stations with signal from those with background
  • Visual reconstruction of the arrival direction of the primary cosmic ray
  • Fitting the data to determine the energy of the primary cosmic ray
  • Application of criteria to select events which point to the source
  • Interpretation of sky maps in different coordinate systems
