Isotropy of cosmic rays beyond eV favors their heavy mass composition
Telescope Array Collaboration, R. U. Abbasi, Y. Abe +138
We report an estimation of the injected mass composition of ultra-high energy cosmic rays (UHECRs) at energies higher than 10 EeV. The composition is inferred from an energy-depend…
Mass composition of ultra-high energy cosmic rays from distribution of their arrival directions with the Telescope Array
Telescope Array Collaboration, R. U. Abbasi, Y. Abe +138
We use a new method to estimate the injected mass composition of ultrahigh cosmic rays (UHECRs) at energies higher than 10 EeV. The method is based on comparison of the energy-depe…
Observation of Declination Dependence in the Cosmic Ray Energy Spectrum
The Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +122
We report on an observation of the difference between northern and southern skies of the ultrahigh energy cosmic ray energy spectrum with a significance of . We use measu…
Observation of Variations in Cosmic Ray Single Count Rates During Thunderstorms and Implications for Large-Scale Electric Field Changes
R. U. Abbasi, T. Abu-Zayyad, M. Allen +160
We present the first observation by the Telescope Array Surface Detector (TASD) of the effect of thunderstorms on the development of cosmic ray single count rate intensity over a 7…
Indications of a Cosmic Ray Source in the Perseus-Pisces Supercluster
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +155
The Telescope Array Collaboration has observed an excess of events with in the data which is centered at (RA, dec) = (, ). This is n…
The Cosmic-Ray Composition between 2 PeV and 2 EeV Observed with the TALE Detector in Monocular Mode
Telescope Array Collaboration
We report on a measurement of the cosmic ray composition by the Telescope Array Low-Energy Extension (TALE) air fluorescence detector (FD). By making use of the Cherenkov light sig…
