Millisecond pulsars as VHE gamma-ray sources

Abstract

The detectability of millisecond pulsars in VHE gamma-ray bracket (>5x10 to the power 11 eV), with the recently-commissioned TACTIC array, has been investigated on the basis of system energetics and the pulsar polar gap model.It is shown that, out of the 24 millisecond pulsars with known values of period, period derivative and distance, at least two millisecond pulsars qualify as potentially detectable by the TACTIC array above 0.5 TeV photon energy.
