Abstract

It is shown that, while the number of Geminga-like pulsars in the Galaxy may be [FORMULA], the prospects of detecting TeV gamma-ray signals from them are not very encouraging. Arguments are presented to show that Geminga-like pulsars having periods in the range 200-500 ms, surface magnetic fields [FORMULA] Gauss and preferentially located within [FORMULA] of the earth may be able to produce detectable TeV gamma-ray signals.

Key words: pulsars: individual: Geminga — pulsars: general — gamma rays: theory
