30TH INTERNATIONAL COSMIC RAY CONFERENCE Search for pulsed emission of TeV gamma rays from Geminga Pulsar

Abstract: Pulsed emission of γ-rays from Geminga pulsar were detected at the period of ∼ 237 ms by satelliet-borne detectors. However, there are conflicting reports about emission of γ-rays from this pulsar at Very High Energies. We have observed this source for about 56 hours during the year 2000 to 2006 using the PACT setup at a threshold energy of ∼ 850 GeV. This pulsar was found by Jackson et al. to undergo a minor glitch in late 1996. We have analysed our data by using post glitch pulsar elements and using the ”TEMPO ” computer code for calculating the pulsar phase for each event. We do not see any significant evidence of pulsed emission of γ-rays from this object. In this paper we describe our data, analysis procedure and the results
