Reanalyze the pulsar scenario to explain the cosmic positron excess considering the recent developments
Kun Fang, Xiao-Jun Bi, Peng-Fei Yin
As the TeV halos around Geminga and PSR B0656+14 have been confirmed by HAWC, slow diffusion of cosmic rays could be general around pulsars, and the cosmic positron spectrum from p…
First Detection of Photons with Energy Beyond 100 TeV from an Astrophysical Source
M. Amenomori, Y. W. Bao, X. J. Bi +88
We report on the highest energy photons from the Crab Nebula observed by the Tibet air shower array with the underground water-Cherenkov-type muon detector array. Based on the crit…
Time dependent solar modulation of cosmic rays from solar minimum to solar maximum
Bing-Bing Wang, Xiao-Jun Bi, Kung Fang +2
We study the time-dependent modulation effect and derive the local interstellar spectra (LIS) for the cosmic ray (CR) proton, helium, boron and carbon. A two-dimensional modulation…
Possible origin of the slow-diffusion region around Geminga
Kun Fang, Xiao-Jun Bi, Peng-Fei Yin
Geminga pulsar is surrounded by a multi-TeV -ray halo radiated by the high energy electrons and positrons accelerated by the central pulsar wind nebula (PWN). The angular profil…
