Evidence of cosmic-ray acceleration up to sub-PeV energies in the supernova remnant IC 443
Zhen Cao, F. Aharonian, Y. X. Bai +309
Supernova remnants (SNRs) have been considered as the primary contributors to cosmic rays (CRs) in our Galaxy. However, the maximum energy of particles that can be accelerated by s…
LHAASO observation of Mrk 421 during 2021 March - 2024 March: a comprehensive VHE catalog of multi-timescale outbursts and its time average behavior
The LHAASO Collaboration, Zhen Cao, F. Aharonian +321
The Large High Altitude Air Shower Observatory (LHAASO) monitors sources within its field of view for up to 7 hours daily, achieving a duty cycle exceeding 98% and an annual point-…
Measurement of Very-high-energy Diffuse Gamma-ray Emissions from the Galactic Plane with LHAASO-WCDA
The LHAASO Collaboration, Zhen Cao, F. Aharonian +312
The diffuse Galactic gamma-ray emission is a very important tool used to study the propagation and interaction of cosmic rays in the Milky Way. In this work, we report the measurem…
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 L…
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 cosm…
Monitoring the daily variation of Sun-Earth magnetic fields using galactic cosmic rays
The LHAASO Collaboration, C. W. Jiang, Y. Yang
The interplanetary magnetic field (IMF) between the Sun and Earth is an extension of the solar magnetic field carried by the solar wind into interplanetary space. Monitoring variat…
