In the present-day cosmic ray data, the strongest indication of anisotropy of the ultrahigh
energy cosmic rays is the 20-degree hotspot observed by the Telescope Array with the …

Motivated by the detection of a significant dipole structure in the arrival directions of ultra-
high-energy cosmic rays above 8 EeV reported by the Pierre Auger Observatory (Auger), we …

The Telescope Array (TA) experiment is located in the western desert of Utah, USA, and
observes ultra high energy cosmic rays (UHECRs) in the Northern hemisphere. At the …

We study the anisotropy of Ultra-High Energy Cosmic Ray (UHECR) events collected by the
Telescope Array (TA) detector in the first 40 months of operation. Following earlier studies …

The origin of ultra-high-energy cosmic rays (UHECRs), which reach energy 1020 eV,
remains the mysteries in modern astrophysics. The main obstacles in identifying the origin of …

Abstract The Telescope Array (TA) experiment, the largest observatory studying ultrahigh
energy cosmic rays in the northern hemisphere, has reported an excess in the arrival …

The Telescope Array (TA) is the largest detector in the northern hemisphere to explore the
origin of ultra‐high energy cosmic rays (UHECR). Here we present the status and …

More than 50 years have passed since the first 1020 eV candidate was registered [1], but the
origin of cosmic rays with energy above 50 EeV is still a mystery. At present, two …

Abstract The Telescope Array (TA) collaboration has reported a hotspot of 19 ultrahigh-
energy cosmic rays (UHECRs). Using a universal model with one source and energy …
