Exploring Constraints on Axion-like Particles with the Observations for blazar Mrk 501
Ting Zhou, Lin-Qing Gao, Xiao-Jun Bi +2
Oscillations between axion-like particles (ALPs) and photons in astrophysical magnetic fields can lead to irregularities in the high energy gamma ray spectra of blazars. The magnet…
Impact of Parameters in the Blazar Jet Magnetic Field Model on Axion-Like Particle Constraints
Lin-Qing Gao, Xiao-Jun Bi, Jun Li +1
The interaction between axion-like particles (ALPs) and photons induces ALP-photon oscillations in astrophysical magnetic fields, leading to spectral distortions in the -ray spe…
Constraints on Axion-like Particles from the Observation of Galactic Sources by LHAASO
Jun Li, Xiao-Jun Bi, Lin-Qing Gao +3
High-energy photons may oscillate with axion-like particles (ALPs) when they propagate through the Milky Way's magnetic field, resulting in an alteration in the observed photon ene…
Optimization of performance of the KM2A full array using the Crab Nebula
LHAASO collaboration
The full array of the Large High Altitude Air Shower Observatory (LHAASO) has been in operation since July 2021. For its kilometer-square array (KM2A), we have optimized the select…
Constraints on Axion-like Particles from the Observation of GRB 221009A by LHAASO
Lin-Qing Gao, Xiao-Jun Bi, Jun Li +2
The LHAASO collaboration recently reported the measurement of the gamma-ray spectra of GRB 221009A, which is the brightest burst ever, covering an energy range from 0.3 $\mathrm{Te…
