EGRET Image of the Galactic Anticenter

EGRET Image of the Galactic Anticenter

This EGRET image shows Geminga (above and left of center) and the Crab nebula (below and right of center), two bright sources of gamma rays in the direction of the Galactic anticenter. Both Geminga and the Crab contain pulsars which pulse at gamma-ray energies. Strikingly, Geminga mainly pulses in the X-ray and gamma-ray regimes with very little pulsation at other wavelengths, while the Crab pulsar is observed to generate optical and radio pulses as well. The faint source visible just below center is the active galaxy designated PKS 0528+134.
