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…
First Detection of Photons with Energy Beyond 100 TeV from an Astrophysical Source
M. Amenomori, Y. W. Bao, X. J. Bi +88
We report on the highest energy photons from the Crab Nebula observed by the Tibet air shower array with the underground water-Cherenkov-type muon detector array. Based on the crit…
Galactic Cosmic-Ray Anisotropy in the Northern hemisphere from the ARGO-YBJ Experiment during 2008-2012
B. Bartoli, P. Bernardini, X. J. Bi +69
This paper reports on the observation of the sidereal large-scale anisotropy of cosmic rays using data collected by the ARGO-YBJ experiment over 5 years (20082012). This analysi…
The Knee of the Cosmic Hydrogen and Helium Spectrum below 1 PeV Measured by ARGO-YBJ and a Cherenkov Telescope of LHAASO
B. Bartoli, P. Bernardini, X. J. Bi +93
The measurement of cosmic ray energy spectra, in particular for individual species, is an essential approach in finding their origin. Locating the "knees" of the spectra is an impo…
Energy Spectrum of Cosmic Protons and Helium Nuclei by a Hybrid Measurement at 4300 m a.s.l
B. Bartoli, P. Bernardini, X. J. Bi +97
The energy spectrum of cosmic Hydrogen and Helium nuclei has been measured, below the so-called "knee", by using a hybrid experiment with a wide field-of-view Cherenkov telescope a…
Highlights from the ARGO-YBJ experiment
G. Di Sciascio
The ARGO-YBJ experiment is a multipurpose detector exploiting the full coverage approach at very high altitude. The apparatus, in stable data taking since November 2007 with an ene…
ARGO-YBJ constraints on very high energy emission from GRBs
YBJ Collaboration, G. Aielli
The ARGO-YBJ (Astrophysical Radiation Ground-based Observatory at YangBaJing) experiment is designed for very high energy -astronomy and cosmic ray researches. Due to the full c…
