The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey--IV. Survey update and an atlas of 205 non-recycled southern pulsars
N. D. R. Bhat, C. P. Lee, S. J. McSweeney +13
The SMART survey is an ambitious effort to conduct sensitive searches for pulsars and fast transients at 140-170 MHz. The novelty of voltage recording, long dwell times and the hig…
Pulsar searches of Fermi-LAT gamma-ray sources with the MWA
C. P. Lee, N. D. R. Bhat, B. W. Meyers +2
Searches of unassociated gamma-ray sources in the Fermi-LAT catalogues have led to the discoveries of around a fifth of all known millisecond pulsars (MSPs). These searches have al…
An Introduction to Single-Antenna Radio Astronomical Polarimetry
Willem van Straten
This tutorial reviews the mathematical foundations of single-antenna radio polarimetry with the aim of fostering a conceptual understanding of the relationships between a physical…
The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey -- III. A census of millisecond pulsars at 154 MHz
C. P. Lee, N. D. R. Bhat, B. W. Meyers +9
Observations of millisecond pulsars (MSPs) at low radio frequencies play an important role in understanding the Galactic pulsar population and characterising both their emission pr…
Generalized Steppingstone Sampling: Efficient marginal likelihood estimation in gravitational wave analysis of Pulsar Timing Array data
El Mehdi Zahraoui, Patricio Maturana-Russel, Willem van Straten +2
Globally, Pulsar Timing Array (PTA) experiments have revealed evidence supporting an existing gravitational wave background (GWB) signal in the PTA data set. Apart from acquiring m…
Bow Shock and Local Bubble Plasma Unveiled by the Scintillating Millisecond Pulsar J04374715
Daniel J. Reardon, Robert Main, Stella Koch Ocker +10
The ionized interstellar medium contains au-scale (and below) structures that scatter radio waves from pulsars, resulting in scintillation. Power spectral analysis of scintillation…
