Subpulse Modulation in PSR B 0320 + 39

We report on an analysis of the drifting subpulses of PSR B0320+39 that indicates a sudden step of ∼ 180 degrees in subpulse phase near the centre of the pulse profile. The phase step, in combination with the attenuation of the periodic subpulse modulation at pulse longitudes near the step, suggests that the patterns arise from the addition of two superposed components of nearly opposite drift ...

AND ASTROPHYSICS Null-induced mode changes in PSR B0809+74

We have found that there are two distinct emission modes in PSR B0809+74. Beside its normal and most common mode, the pulsar emits in a significantly different quasi-stable mode after most or possibly all nulls, occasionally for over 100 pulses. In this mode the pulsar is brighter, the subpulse separation is less, the subpulses drift more slowly and the pulse window is shifted towards earlier l...

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...

Nustar Hard X-ray Observations of the Energetic Millisecond Pulsars Psr B1821−24, Psr B1937+21, and Psr J0218+4232

We present Nuclear Spectroscopic Telescope Array (NuSTAR) hard X-ray timing and spectroscopy of the three exceptionally energetic rotation-powered millisecond pulsars PSRs B1821−24, B1937+21, and J0218+4232. By correcting the NuSTAR on-board clock for phase and frequency drifts between observation intervals, we are able to recover the intrinsic hard X-ray pulse profiles of all three pulsars wit...

PSR 38.indd

ion is not something which the mind produces by processes of logic from its perception of reality, but rather a property of the categories with which it operates—not a product of the mind but rather what constitutes the mind. We never act, and could never act, in full consideration of all the facts of a particular situation, but always by singling out as relevant only some aspects of it; not by...
