Precise Measurement of the Cosmic Ray Helium Spectrum above 0.1 PeV

LHAASO Collaboration, Zhen Cao, F. Aharonian +321

We report a measurement of the cosmic ray helium energy spectrum in the energy interval 0.16 -- 13~PeV, derived by subtracting the proton spectrum from the light component~(proton…

Ground-based Observations of Temporal Variation of Cosmic Ray Spectrum during Forbush Decreases

W. Mitthumsiri, D. Ruffolo, K. Munakata +29

Observations of temporary Forbush decreases (FDs) in the Galactic cosmic ray (GCR) flux due to passage of solar storms are useful for space weather studies and alerts. Here we intr…

Precise measurements of the cosmic ray proton energy spectrum in the "knee'' region

The LHAASO Collaboration, Zhen Cao, F. Aharonian +310

We report the high-purity identification of cosmic-ray (CR) protons and a precise measurement of their energy spectrum from 0.15 to 12 PeV using the Large High Altitude Air Shower…

Study of Ultra-High-Energy Gamma-Ray Source 1LHAASO J0056+6346u and Its Possible Origins

Zhen Cao, F. Aharonian, Y. X. Bai +322

We report a dedicated study of the newly discovered extended UHE -ray source 1LHAASO J0056+6346u. Analyzing 979 days of LHAASO-WCDA data and 1389 days of LHAASO-KM2A data, we ob…

Constraining the Cosmic-ray Energy Based on Observations of Nearby Galaxy Clusters by LHAASO

The LHAASO Collaboration, Zhen Cao, F. Aharonian +323

Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse -rays detectable by arrays such as LH…

An Enigmatic PeVatron in an Area around HII Region G35.60.5

The LHAASO Collaboration, Zhen Cao, F. Aharonian +294

Identifying Galactic PeVatrons (PeV particle accelerators) from the ultra-high-energy (UHE, >100 TeV) -ray sources plays a crucial role in revealing the origin of Galactic cosmi…
