A discussion on the origin of the sub-PeV Galactic gamma-ray emission
S. Kato, R. Alves Batista, M. Anzorena +16
Galactic diffuse gamma-ray flux measured by the Tibet AS experiment and the total Galactic gamma-ray flux measured by Large High Altitude Air Shower Observatory (LHAASO) are fou…
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…
Quantitative constraint on the contribution of resolved gamma-ray sources to the sub-PeV Galactic diffuse gamma-ray flux measured by the Tibet ASγ experiment
S. Kato, M. Anzorena, D. Chen +13
Motivated by the difference between the fluxes of sub-PeV Galactic diffuse gamma-ray emission (GDE) measured by the Tibet AS experiment and the LHAASO collaboration, our study c…
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…
