We investigate the use of bright single pulses from the Crab pulsar to determine separately the dispersion measure (DM) for the Main Pulse and Interpulse components. We develop two approaches using cross correlation functions (CCFs). The first method

Pulsar 0301+19, whose two well-separated components provide a textbook example of the conal double profile, apparently evolves to ajeingle form at frequencies above 5 GHz. PSR 2016+28, by contrast, exhibits a single form above 200 MHz, but bifurcates

Our high time resolution observations of individual pulses from the Crab pulsar show that the main pulse and interpulse differ in temporal behavior, spectral behavior, polarization and dispersion. The main pulse properties are consistent with one cur

Individual giant radio pulses (GRPs) from the Crab pulsar last only a few microseconds. However, during that time they rank among the brightest objects in the radio sky reaching peak flux densities of up to 1500 Jy even at high radio frequencies. Our

Following the analysis by Krishnamohan and Downs (1983) of the Vela pulsar, we have investigated the behavior of the core and outrider components of PSR 0329+54 by calculating pulse profiles at different pulse intensities. VLA observations of individ

We present an analysis of high signal-to-noise ratio, 430-MHz total intensity single pulse observations from PSR 2303+30 recorded at the Arecibo Observatory in August 1986. We believe that the regular subpulse modulation observed in this pulsar can b

A hardware real‐time coherent dedispersion filter based on the Reticon 5601A Quad Chirped Transversal Filter is shown to be effective for time‐resolution improvement of pulsar measurements. The filter can completely remove the time distortion due

PSR1237 + 25, one of the first pulsars to be discovered1,2, is characterized by a striking five-peaked integrated intensity profile. Like many other pulsars, PSR1237 + 25 also exhibits the puzzling phenomena of drifting subpulses, ‘nulling’ and
