59. TA Spectrum Summary

Dmitri Ivanov (University of Utah)

10/11/16, 9:10 AM

This work summarizes the cosmic ray energy spectrum measurement by the Telescope Array Experiment (TA) in the energy range from 4 PeV to over 100 EeV. The TA is a hybrid detector that uses 3 air fluorescence detectors (FDs) overlooking a ground array of scintillation counters of 1200 m spacing. In May 2016, TA has collected 8 years of data. The TA low energy extension (TALE) extends the energy...

39. Measurement of the energy spectrum of cosmic rays with the Pierre Auger Observatory

Markus Roth (KIT)

10/11/16, 9:30 AM

The flux of cosmic rays has been measured with unprecedented precision at the Pierre Auger Observatory. We report on the recent update of the all-sky flux of cosmic rays above $3{\times}10^{17}$eV obtained by combining four independent high-quality data sets collected for more than 10 years, with a total exposure exceeding 50,000 km$^2$sr yr. These measurements are based on data from the...

37. Auger-TA energy spectrum working group report

Dr Valerio Verzi (INFN Roma Tor Vergata)

10/11/16, 9:55 AM

The energy spectrum joint working group was re-established with membership from the Pierre Auger Observatory (Auger) and the Telescope Array experiment (TA). In-depth discussions on the energy determination and systematic uncertainties in the two experiments were made, resulting in a detailed comparison of the UHECR energy spectra observed in the southern and the northern hemispheres. The flux...
