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…
Stringent Tests of Lorentz Invariance Violation from LHAASO Observations of GRB 221009A
The LHAASO Collaboration, Zhen Cao, F. Aharonian +283
On October 9, 2022, the Large High Altitude Air Shower Observatory (LHAASO) reported the observation of the very early TeV afterglow of the brightest-of-all-time GRB 221009A, recor…
Multi-wavelength Study of A Superflare on RS CVn-type Star HD22468 Triggered at Hard X-ray by SVOM
J. Wang, W. J. Xie, F. Cangemi +36
Detection of stellar flares at hard X-ray is still rare at the current stage. A transient was recently detected by the hard X-ray camera, ECLAIRs onboard the SVOM mission at 11:39:…
SVOM discovery of a strong X-ray outburst of the blazar 1ES~1959+650 and multi-wavelength follow-up with the Neil Gehrels Swift observatory
A. Foisseau, A. Coleiro, S. Komossa +37
On December 6, 2024, 1ES 1959+650, one of the X-ray brightest blazars known, underwent a high-amplitude X-ray outburst detected by SVOM, the first such discovery with this mission.…
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…
