Observation of the Forbush decrease on 2024 May 10, using the ALPAQUITA air-shower array at the 70-1000 GV rigidity range
M. Anzorena, E. de la Fuente, K. Fujita +49
The Andes Large area PArticle detector for Cosmic ray and Astronomy (ALPACA) is a new air-shower array experiment under construction in the Bolivian Andes, and its prototype ALPAQU…
Searching for EeV photons with Telescope Array Surface Detector and neural networks
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126
Ultra-high-energy photons play an important role in probing astrophysical models and beyond-Standard-Model scenarios. We report updated limits on the diffuse photon flux using Tele…
A new air shower array in the Southern Hemisphere looking for the origins of Cosmic rays: the ALPACA experiment
M. Anzorena, E. de la Fuente, K. Fujita +53
The Tibet AS experiment successfully detected sub-PeV -rays from the Crab nebula using a Surface Array and underground muon detector. Considering this, we are building in Bol…
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…
