Mode Switching and Subpulse Drifting in PSR B 0826 − 34
We present high-quality observations of PSR B0826−34 at 1374 MHz. The emission from this pulsar exhibits strong bursts of pulses followed by long periods of ‘null’ pulses. When it is strong, the radiation extends through the whole pulse period. We show for the first time that there is weak emission during the ‘null’ phases, which should therefore be considered to be a different mode rather than...
متن کاملAn unusual pulsar wind nebula associated with PSR B 0906
We report on Australia Telescope Compact Array observations of the ∼105 yr old pulsar PSR B0906–49. In an image containing only off-pulse emission, we find a weak, slightly extended source coincident with the pulsar’s position, which we argue is best interpreted as a pulsar wind nebula (PWN). A trail of emission extending behind the pulsar aligns with the major axis of the PWN, and implies that...

متن کاملAn unusual glitch signature in the pulsar PSR B1822-09
Two glitches have been detected in the pulsar PSR B1822-09. The first glitch occurred around MJD 49615 and was characterized by a fractional increase in rotational frequency of 2×10−10. The second glitch occurred 325 days after the first one and caused a fractional change in frequency of 5×10−9. Of interest was the post-glitch behaviour. The rotational frequency immediately after the second gli...
متن کاملThe Unusual Binary Pulsar Psr J1744−3922: Radio Flux Variability, Near-infrared Observation and Evolution
PSR J1744−3922 is a binary pulsar exhibiting highly variable pulsed radio emission. We report on a statistical multi-frequency study of the pulsed radio flux variability which suggests that this phenomenon is extrinsic to the pulsar and possibly tied to the companion, although not strongly correlated with orbital phase. The pulsar has an unusual combination of characteristics compared to typica...
