چکیده

We have detected the rare phenomenon of stable, drifting sub-pulse behaviour in two pulsars discovered in the recent Swinburne intermediate latitude pulsar survey. The pulsars; PSR J1231–47 and PSR J1919+0134, have approximate periods (P ) of 1.873 and 1.6039 seconds respectively. Both pulsars have multi-component profiles, and distinct drifting is observed across them. We have identified a single drift mode in both pulsars: the drift rate for PSR J1231-47 being 5.4(1) ms P and 5.8(2) ms P for PSR 1919+0134. The drifting is linear across the profile with no departure from linearity at the edges within the sensitivity of our observations.

The subpulse modulation properties of pulsars at 92 cm and the frequency dependence of subpulse modulation

Context. A large sample of pulsars has been observed to study their subpulse modulation at an observing wavelength (when achievable) of both 21 and 92 cm using the Westerbork Synthesis Radio Telescope. In this paper we present the 92-cm data and a comparison is made with the already published 21-cm results. Aims. The main goals are to determine what fraction of the pulsars have drifting subpuls...

2 00 4 A model for the challenging “ bi - drifting ” phenomenon in PSR J 0815 + 09

A new drifting pulsar, PSR J0815+09, was discovered in the Arecibo driftscan searches (McLaughlin et al. 2004). An intriguing feature of this source is that within the four pulse components in the integrated pulse profile, the subpulse drifting direction in the two leading components is opposite from that in the two trailing components. In view that the leading theoretical model (Ruderman & Sut...

Pulse-to-pulse intensity modulation and drifting subpulses in recycled pulsars

We report the detection of pulse-to-pulse periodic intensity modulations, in observations of recycled pulsars. Even though the detection of individual pulses was generally not possible due to their low flux density and short duration, through the accumulation of statistics over sequences of 105–106 pulses we were able to determine the presence and properties of the pulse-to-pulse intensity vari...

The Subpulse Modulation Properties of Pulsars and its Frequency Dependence

A large sample of about two hundred pulsars have been observed to study their subpulse modulation at an observing wavelength of (when achievable) both 21 and 92 cm using the Westerbork Synthesis Radio Telescope. For 57 pulsars drifting subpulses are discovered for the first time and are confirmed for many others. This leads to the conclusion that it could well be that the drifting subpulse mech...

The Double Pulsar System J0737–3039: Modulation of the Radio Emission from B by Radiation from A

We have analyzed single pulses from PSR J0737−3039B, the 2.8-s pulsar in the recently discovered double pulsar system, using data taken with the Green Bank Telescope at 820 and 1400 MHz. We report the detection of features similar to drifting subpulses, detectable over only a fraction of the pulse window, with a fluctuation frequency of 0.196 cycles/period. This is exactly the beat frequency be...
