Abstract
The Energetic Gamma Ray Experiment Telescope (EGRET) aboard the Compto n Gamma Ray Observatory has detected a high-energy gamma-ray source at a position coincident with that of the radio pulsar PSR 1055-52. Anal ysis of the EGRET data at the radio pulsar period of 197 ms has reveal ed pulsed gamma-radiation at energies above 300 MeV, making PSR 1055-5 2 the fifth detected high-energy gamma-ray pulsar. The pulsed radiatio n from PSR 1055 - 52 has a very hard photon spectral index of -1.18 +/ - 0.16 and a high efficiency for converting its rotational energy into gamma-rays. No unpulsed emission was observed.
