Limits to quantum gravity effects on energy dependence of the speed of light from observations of tev flares in active galaxies
(American Physical Society (APS), 1999-09-13)
We have used data from a TeV gamma-ray flare associated with the active galaxy Markarian 421 to place bounds on the possible energy dependence of the speed of light in the context of an effective quantum gravitational ...
Very high‐energy observations of psr b1951+32
(IOP Publishing, 1997-11-01)
PSR B1951 + 32 is a gamma-ray pulsar detected by the Energetic Gamma Ray Experiment Telescope (EGRET) and identified with the 39.5 ms radio pulsar in the supernova remnant CTB 80. The pulsar energy spectrum is consistent ...
