Probing turbulence in the ionized interstellar medium using young pulsars. I. Dispersion measure variations
S. J. I. Melfor, A. Parthasarathy, S. Johnston +9
Temporal variations in the dispersion measure (DM) of pulsars probe fluctuations in the free-electron density of the ionized interstellar medium (IISM). While DM variations have be…
Frequency evolution of pulsar emission: Further evidence for fan beam model
P. Jaroenjittichai, S. Johnston, S. Dai +7
Aims. We explore frequency-dependent changes in pulsar radio emission by analyzing their profile widths and emission heights, assessing whether the simple radius-to-frequency mappi…
Discovery and Timing of Four -ray Millisecond Pulsars
M. Kerr, S. Johnston, C. J. Clark +11
We discovered four millisecond pulsars (MSPs) in searches of 80 -ray sources conducted from 2015 to 2017 with the Murriyang radio telescope of the Parkes Observatory. We provide…
The ubiquity of variable radio emission and spin-down rates in pulsars
M. E. Lower, A. Karastergiou, S. Johnston +8
Pulsars are often lauded for their (relative) rotational and radio emission stability over long time scales. However, long-term observing programmes are identifying an increasing n…
PSR J1631-4722: The Discovery of a Young and Energetic Pulsar in the Supernova Remnant G336.7+0.5
A. Ahmad, S. Dai, S. Lazarević +6
Detecting a pulsar associated with a supernova remnant (SNR) and/or pulsar wind nebula (PWN) is crucial for unraveling its formation history and pulsar wind dynamics, yet the assoc…
The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background
J. Antoniadis, Z. Arzoumanian, S. Babak +123
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…
A pilot ASKAP survey of radio transient events in the region around the intermittent pulsar PSR J1107-5907
G. Hobbs, I. Heywood, M. E. Bell +75
We use observations from the Boolardy Engineering Test Array (BETA) of the Australian Square Kilometre Array Pathfinder (ASKAP) telescope to search for transient radio sources in t…
