Implications of the Detection of pulsed TeV Gamma-Rays from Geminga
Abstract
The implications of the recently reported 237 ms pulsed TeV gamma-ray signal from Geminga with respect to system energetics and gamma-ray emission mechanisms are discussed. Using the reported flux values in the MeV-GeV range from the EGRET and COMPTEL experiments and the published results on TeV emission, the derived emission spectrum of Geminga in the MeV-TeV energy range is shown to suggest a spectral break at ∼2 GeV, with the differential exponent changing from a value of ∼-1.50 upto 2 GeV to a value of ∼-2.7 in the TeV range.
