Modelling Annual Scintillation Velocity Variations of FRB 20201124A
R. A. Main, S. Bethapudi, V. R. Marthi +5
Compact radio sources exhibit scintillation, an interference pattern arising from propagation through inhomogeneous plasma, where scintillation patterns encode the relative distanc…
The Thousand-Pulsar-Array program on MeerKAT -- IX. The time-averaged properties of the observed pulsar population
B. Posselt, A. Karastergiou, S. Johnston +14
We present the largest single survey to date of average profiles of radio pulsars, observed and processed using the same telescope and data reduction software. Specifically, we pre…
The Thousand-Pulsar-Array programme on MeerKAT -- X. Scintillation arcs of 107 pulsars
R. A. Main, A. Parthasarathy, S. Johnston +9
We present the detection of 107 pulsars with interstellar scintillation arcs at 856--1712\,MHz, observed with the MeerKAT Thousand Pulsar Array Programme. Scintillation arcs appear…
Resolving the Emission Regions of the Crab Pulsar's Giant Pulses II. Evidence for Relativistic Motion
Rebecca Lin, Marten H. van Kerkwijk, Robert Main +3
The Crab Pulsar is the prime example of an emitter of giant pulses. These short, very bright pulses are thought to originate near the light cylinder, at from…
Plasma lensing near the eclipses of the Black Widow pulsar B1957+20
Fang Xi Lin, Robert Main, Dylan Jow +3
Recently, several eclipsing millisecond pulsars have been shown to experience strong and apparent weak lensing from the outflow of their ionized companions. Lensing can be a powerf…
DM-power: an algorithm for high precision dispersion measure with application to fast radio bursts
Hsiu-Hsien Lin, Robert Main, Ue-Li Pen +7
We present DM-power, a new method for precisely determining the dispersion measure (DM) of radio bursts, and apply it to the Fast Radio Burst (FRB) source FRB~20180916B. Motivated…
