Abstract

HALPERN and Holt¹ have recently reported the detection of coherent pulsations with a period of 237 ms from the soft X-ray source 1E0630+178, which lies in the error box of the γ-ray source known as Geminga (2GC195+04). This observation provides compelling evidence that Geminga, an object whose nature has hitherto been mysterious, is an X-ray pulsar. Prompted by this discovery, we have searched the data from EGRET, the Energetic Gamma Ray Experiment Telescope on the Compton Gamma Ray Observatory, for a comparable signal in the γ-radiation from this part of the sky. We now report the detection of pulsed γ-rays, with energy >50 MeV, from 1E0630+178, confirming the identification of Geminga with this X-ray source. The period derivative, (11.4±1.7) × 10^-15 s s^-1, suggests that Geminga is a nearby, isolated, rotating neutron star with a magnetic field of 1.6 × 10¹² gauss, a characteristic age of 3 × 10⁵ yr and a spin-down energy loss rate of 3.5 × 10³⁴ erg s^-1.
