The Extended Ultrahigh-energy Gamma-Ray Emission in the Vicinity of PSR J2238+5903
Zhen Cao, F. Aharonian, Y. X. Bai +324
We present a comprehensive analysis of the recently discovered TeV gamma-ray source, LHAASO J2238+5900. Based on data collected from the LHAASO, our fitting results suggest that th…
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…
Exploring Lorentz Invariance Violation from Ultra-high-energy Gamma Rays Observed by LHAASO
Zhen Cao, F. Aharonian, Q. An +268
Recently the LHAASO Collaboration published the detection of 12 ultra-high-energy gamma-ray sources above 100 TeV, with the highest energy photon reaching 1.4 PeV. The first detect…
Transient Large-Scale Anisotropy in TeV Cosmic Rays due to an Interplanetary Coronal Mass Ejection
Zhen Cao, F. Aharonian, Y. X. Bai +309
Large- or medium-scale cosmic ray anisotropy at TeV energies has not previously been confirmed to vary with time. Transient anisotropy changes have been observed below 150 GeV, esp…
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…
