Geminga pulsar observations with gamma-telescope Gamma-1
Abstract
The Geminga light curve obtained with the “Gamma-1” telescope features two peaks separated by 0.5 ± 0.03 period. The light curve is pronounced for γ-quanta energies higher than 400 MeV. The pulsed flux upper limit (1σ) in the energy interval 50 - 300 MeV is 6·10-7 cm-2sec-1. For energies >300 MeV the pulsed component power law spectrum has an exponent 1.1-0.3+1.1 and an integral flux (1.1±0.3)·10-6cm-2sec-1.
