Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +339
Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…
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…
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…
Observations of the Fermi bubbles and the Galactic center excess with the DArk Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +145
The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle detector that surveys the -ray sky above with a peak acceptance of $\sim 0.2~\rm…
The First GeV Gamma-Ray Flares from the CSO-like Source 4C 76.03
Xiong Jiang, Hai Lei, Hao-Yi Huang +3
We report the first detection of GeV gamma-ray flaring activity from the compact symmetric object (CSO)-like source 4C 76.03, based on 17 years of Fermi-LAT observations. Its long-…
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…
