Magnetic equilibria of relativistic axisymmetric stars: The impact of flow constants
Arthur G. Suvorov, Kostas Glampedakis
Symmetries and conservation laws associated with the ideal Einstein-Euler system, for stationary and axisymmetric stars, can be utilized to define a set of flow constants. These qu…
Improving pulsar polarization and timing measurements with the Nançay Radio Telescope
Lucas Guillemot, Ismaël Cognard, Willem van Straten +2
Accurate polarimetric calibration of the radio pulse profiles from pulsars is crucial for studying their radiation properties at these wavelengths. Inaccurate calibration can also…
The gravitational-wave background null hypothesis: Characterizing noise in millisecond pulsar arrival times with the Parkes Pulsar Timing Array
Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +19
The noise in millisecond pulsar (MSP) timing data can include contributions from observing instruments, the interstellar medium, the solar wind, solar system ephemeris errors, and…
Search for an isotropic gravitational-wave background with the Parkes Pulsar Timing Array
Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +26
Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common t…
Radio Variable and Transient Sources on Minute Timescales in the ASKAP Pilot Surveys
Yuanming Wang, Tara Murphy, Emil Lenc +12
We present results from a radio survey for variable and transient sources on 15-min timescales, using the Australian SKA Pathfinder (ASKAP) pilot surveys. The pilot surveys consist…
The Parkes Pulsar Timing Array Third Data Release
Andrew Zic, Daniel J. Reardon, Agastya Kapur +31
We present the third data release from the Parkes Pulsar Timing Array (PPTA) project. The release contains observations of 32 pulsars obtained using the 64-m Parkes "Murriyang" rad…
Mass measurements and 3D orbital geometry of PSR J19336211
M. Geyer, V. Venkatraman Krishnan, P. C. C. Freire +19
PSR J19336211 is a 3.5-ms pulsar in a 12.8-d orbit with a white dwarf (WD). Its high proper motion and low dispersion measure result in such significant interstellar scintillati…
Measuring spin in coalescing binaries of neutron stars showing double precursors
Hao-Jui Kuan, Arthur G. Suvorov, Kostas D. Kokkotas
Gamma-ray bursts resulting from binary neutron-star mergers are sometimes preceded by precursor flares. These harbingers may be ignited by quasi-normal modes, excited by orbital re…
Searching for continuous Gravitational Waves in the second data release of the International Pulsar Timing Array
M. Falxa, S. Babak, P. T. Baker +123
The International Pulsar Timing Array 2nd data release is the combination of datasets from worldwide collaborations. In this study, we search for continuous waves: gravitational wa…
Pulsar Scintillation Studies with LOFAR: II. Dual-frequency scattering study of PSR J0826+2637 with LOFAR and NenuFAR
Ziwei Wu, William A. Coles, Joris P. W. Verbiest +28
Interstellar scattering (ISS) of radio pulsar emission can be used as a probe of the ionised interstellar medium (IISM) and causes corruptions in pulsar timing experiments. Two typ…
The radio shut-off, glitch, and X-ray burst in 1E 1547.0-5408 interpreted through magnetic reconfiguration
Arthur G. Suvorov
A short X-ray burst was observed from the radio-loud magnetar 1E 1547.0-5408 in 2022 April. Unusually however, the source stopped showing radio pulsations weeks prior…
Evolutionary implications of a magnetar interpretation for GLEAM-X J162759.5-523504.3
Arthur G. Suvorov, Andrew Melatos
The radio pulsar GLEAM-X J162759.5-523504.3 has an extremely long spin period ($P = 1091.17\, \mbox{s}$), and yet seemingly continues to spin down rapidly ($\dot{P} < 1.2 \times 10…
Milliarcsecond Structures of Variable Peaked-Spectrum Sources
K. Ross, C. Reynolds, N. Seymour +3
Spectral variability offers a new technique to identify small scale structures from scintillation, as well as determining the absorption mechanism for peaked-spectrum (PS) radio so…
