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…
A Simulation Study on the Cosmic Ray Energy Spectra of Elemental Mass Groups using the Tibet Air Shower and Muon Detector Arrays through the Bayesian Unfolding Method
G. Imaizumi, M. Anzorena, K. Fujita +11
We study the analysis method to determine the cosmic-ray energy spectra of different mass groups assuming the use of the Tibet AS experiment, which consists of the high-density…
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…
On the source contribution to the Galactic diffuse gamma rays above 398 TeV detected by the Tibet ASγ experiment
S. Kato, D. Chen, J. Huang +8
Potential contribution from gamma-ray sources to the Galactic diffuse gamma rays observed above 100 TeV (sub-PeV energy range) by the Tibet ASγ experiment is an important key to in…
Observation of gamma rays up to 320 TeV from the middle-aged TeV pulsar wind nebula HESS J1849000
M. Amenomori, S. Asano, Y. W. Bao +115
Gamma rays from HESS J1849000, a middle-aged TeV pulsar wind nebula (PWN), are observed by the Tibet air shower array and the muon detector array. The detection significance of…
Measurement of the Gamma-Ray Energy Spectrum beyond 100 TeV from the HESS J1843033 Region
M. Amenomori, S. Asano, Y. W. Bao +113
HESS J1843033 is a very-high-energy gamma-ray source whose origin remains unidentified. This work presents, for the first time, the energy spectrum of gamma rays beyond $100\, {…
Potential PeVatron supernova remnant G106.3+2.7 seen in the highest-energy gamma rays
M. Amenomori, Y. W. Bao, X. J. Bi +92
Cosmic rays (protons and other atomic nuclei) are believed to gain energies of petaelectronvolts (PeV) and beyond at astrophysical particle accelerators called 'PeVatrons' inside o…
Gamma-ray Observation of the Cygnus Region in the 100 TeV Energy Region
M. Amenomori, Y. W. Bao, X. J. Bi +110
We report observations of gamma-ray emissions with energies in the 100 TeV energy region from the Cygnus region in our Galaxy. Two sources are significantly detected in the directi…
First Detection of sub-PeV Diffuse Gamma Rays from the Galactic Disk: Evidence for Ubiquitous Galactic Cosmic Rays beyond PeV Energies
M. Amenomori, Y. W. Bao, X. J. Bi +92
We report, for the first time, the long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk. Particularly, all gamma rays above 398…
