Gamma-ray photons from young pulsars allow the deepest insight into the properties and interactions of high-energy particles with magnetic and photon fields in a pulsar magnetosphere. Measurements with the Compton Gamma-Ray Observatory have led to the detection of nearly ten γ-ray pulsars . Although quite a variety of individual signatures is found for these pulsars, some general characteristic...

Of the current known pulsars, the Crab pulsar (B0531+21) is one of the most promising sources of gravitational waves. The relatively large timing noise of the Crab causes its phase evolution to depart from a simple spin-down model. This effect needs to be taken in to account when performing time domain searches for the Crab pulsar in order to avoid severely degrading the search efficiency. The ...

Path integration provides guidance based on cues generated by a point of reference (usually start location) and subsequent self-movement. This well-established mechanism suggests start location may have special significance and might provide a useful window into memory in rats. In an earlier study rats did not learn to return to a start location in a four-arm radial water maze when the start lo...
