The event rate, energy distribution, and time-domain behaviour of repeating fast radio bursts (FRBs) contains essential information regarding their physical nature and central engi…
Identifying and mitigating noise sources in precision pulsar timing data sets
Boris Goncharov, D. J. Reardon, R. M. Shannon +14
Pulsar timing array projects measure the pulse arrival times of millisecond pulsars for the primary purpose of detecting nanohertz-frequency gravitational waves. The measurements i…
Mode switching and oscillations in PSR B1828-11
I. H. Stairs, A. G. Lyne, M. Kramer +7
The young pulsar PSR B1828-11 has long been known to show correlated shape and spin-down changes with timescales of roughly 500 and 250 days, perhaps associated with large-scale ma…
Detecting Pulsars with Interstellar Scintillation in Variance Images
S. Dai, S. Johnston, M. E. Bell +4
Pulsars are the only cosmic radio sources known to be sufficiently compact to show diffractive interstellar scintillations. Images of the variance of radio signals in both time and…
