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…
Flat tails in FRB and pulsar energy distributions: implications for optimizing nearby FRB surveys
S. B. Zhang, G. Hobbs, S. Johnston +6
Fast radio bursts (FRBs) are energetic, short-duration radio pulses of unclear origin. To explore effective survey strategies for detecting FRBs from nearby globular clusters (GCs)…
Exploring Unusual High-frequency Eclipses in MSP J1908+2105
Ankita Ghosh, Bhaswati Bhattacharyya, Sangita Kumari +3
This paper presents a comprehensive study of the eclipse properties of the spider millisecond pulsar (MSP) J19082105, using wide-band observations from the uGMRT and Parkes UWL.…
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…
Five New Millisecond Pulsars From a Radio Survey of 14 Unidentified Fermi-LAT Gamma-ray Sources
M. Kerr, F. Camilo, T. J. Johnson +12
We have discovered five millisecond pulsars (MSPs) in a survey of 14 unidentified Fermi-LAT sources in the southern sky using the Parkes radio telescope. PSRs J0101-6422, J1514-494…
