Radio observations of two intermittent pulsars: PSRs J1832+0029 and J1841-0500
Abstract
We present long-term observations of two intermittent pulsars, PSRs J1832+0029 and J1841−0500, using the Parkes 64 m radio telescope. The radio emission for these pulsars switches off for year-long durations. Our new observations have enabled us to improve the determination of the on–off timescales and the spin-down rates during those emission states. In general our results agree with previous studies of these pulsars, but we now have significantly longer data spans. We have identified two unexpected signatures in the data. Weak emission was detected in a single observation of PSR J1832+0029 during an off emission state. For PSR J1841−0500, we identified a quasi-periodic fluctuation in the intensities of the detectable single pulses, with a modulation period between 21 and 36 pulse periods.
