متن کاملRadio pulsar microstructure at 1 . 41 and 4 . 85 GHz
We report on observations of microstructure at 4.85 and 1.41 GHz of pulsars strong enough for the observation of single pulses with time resolution between 7 µs and 160 µs. All five pulsars observed at 4.85 GHz show microstructure in a large fraction of their pulses. We confirm that microstructure seems to be a common property of the pulsar emission mechanism and not only an additional feature ...
متن کاملA Baseband Recorder for Radio Pulsar Observations
Digital signal recorders are becoming widely used in several subfields of centimetre-wavelength radio astronomy. We review the benefits and design considerations of such systems and describe the Princeton Mark IV instrument, an implementation designed for coherent-dedispersion pulsar observations. Features of this instrument include corrections for the distortions caused by coarse quantization ...
متن کاملA Generic Pulsar Radio Emission Mechanism
A generic interpretation of pulsar radio emission that does not rely on the identification of a specific emission mechanism is explored. Coherence is quantified in terms of a coherence factor, which implies a maximum brightness temperature; the possible significance of Poincaré invariants is pointed out, and the potential use of higher order moments of the intensity to measure the coherence is ...
