Abstract:
'The detection of an extended multi-TeV gamma ray emission around thernGeminga pulsar by the HAWC collaboration provides a unique tool to investigate the transport properties of cosmic rays in the turbulent magnetized interstellar medium.rnIn this work, different regimes of propagation of ultrarelativisticrnelectrons in the proximity of pulsars are analyzed and their implicationsrnfor the angular and energy distributions of the resulting secondaryrnradiation are discussed. The results are discussed in the context of the interpretation of therngamma-ray halo around Geminga reported by HAWC.'
