Pulsar Polarization Array Limits on Ultralight Axion-like Dark Matter
Xiao Xue, Shi Dai, Hoang Nhan Luu +20
We conduct the first-ever Pulsar Polarization Array (PPA) analysis to detect the ultralight Axion-Like Dark Matter (ALDM) using the polarization data of 22 millisecond pulsars from…
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…
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…
The birth mass function of neutron stars
Zhi-Qiang You, Xingjiang Zhu, Xiaojin Liu +12
The birth mass function of neutron stars encodes rich information about supernova explosions, double star evolution, and properties of matter under extreme conditions. To date, it…
PSR J1631-4722: The Discovery of a Young and Energetic Pulsar in the Supernova Remnant G336.7+0.5
A. Ahmad, S. Dai, S. LazareviÄ +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…
Precision orbital dynamics from interstellar scintillation arcs for PSR J0437-4715
Daniel J. Reardon, William A. Coles, Matthew Bailes +17
Intensity scintillations of radio pulsars are known to originate from interference between waves scattered by the electron density irregularities of interstellar plasma, often lead…
