Diverse properties of electron Forbush decreases revealed by the Dark Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +147
The Forbush decrease (FD) of cosmic rays is an important probe of the interplanetary environment disturbed by solar activities. In this work, we study the properties of 8 FDs elect…
Probing Lorentz Invariance Violation at High Energies Using LHAASO Observations of GRB221009A via DisCan Algorithm
Yu-Chen Hua, Xiao-Jun Bi, Yu-Ming Yang +1
The Lorentz invariance violation (LIV) predicted by some quantum gravity theories would manifest as an energy-dependent speed of light, which may potentially distort the observed t…
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…
