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…
Study of Ultra-High Energy Cosmic Ray Composition Using Telescope Array's Middle Drum Detector and Surface Array in Hybrid Mode
R. U. Abbasi, M. Abe, T. Abu-Zayyad +123
Previous measurements of the composition of Ultra-High Energy Cosmic Rays(UHECRs) made by the High Resolution Fly's Eye(HiRes) and Pierre Auger Observatory(PAO) are seemingly contr…
Telescope Array Radar (TARA) Observatory for Ultra-High Energy Cosmic Rays
R. Abbasi, M. Abou Bakr Othman, C. Allen +19
Construction was completed during summer 2013 on the Telescope Array RAdar (TARA) bi-static radar observatory for Ultra-High Energy Cosmic Rays (UHECR). TARA is co-located with the…
Indications of Intermediate-Scale Anisotropy of Cosmic Rays with Energy Greater Than 57 EeV in the Northern Sky Measured with the Surface Detector of the Telescope Array Experiment
The Telescope Array Collaboration, R. U. Abbasi, M. Abe +123
We have searched for intermediate-scale anisotropy in the arrival directions of ultrahigh-energy cosmic rays with energies above 57~EeV in the northern sky using data collected ove…
