Testing Gravity with Binary Pulsars in the SKA Era
V. Venkatraman Krishnan, L. Shao, V. Balakrishnan +21
Binary (and trinary) radio pulsars are natural laboratories in space for understanding gravity in the strong field regime, with many unique and precise tests carried out so far, in…
Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKAO
Avishek Basu, Vanessa Graber, Marcus E. Lower +19
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…
Improved proper motion and gravity tests with PSR J1913+1102
Xueli Miao, Paulo C. C. Freire, Norbert Wex +11
PSR J1913+1102 is a highly asymmetric double neutron star system and an excellent laboratory for testing scalar-tensor gravity theories, as well as a potential progenitor analogue…

The double neutron star PSR J1946+2052 I. Masses and tests of general relativity
Lingqi Meng, Paulo C. C. Freire, Kevin Stovall +28
We conducted high-precision timing of PSR J1946+2052 to determine the masses of the two neutron stars in the system, test general relativity (GR) and assessed the system's potentia…
Unlocking Gravity and Gravitational Waves with Radio Pulsars: Advances and Challenges
Huanchen Hu
Pulsars, the cosmic lighthouses, are strongly self-gravitating objects with core densities significantly exceeding nuclear density. Since the discovery of the Hulse--Taylor pulsar…
Rapid Construction of Joint Pulsar Timing Array Datasets: The Lite Method
Bjorn Larsen, Chiara M. F. Mingarelli, Paul T. Baker +41
The International Pulsar Timing Array (IPTA)'s second data release (IPTA DR2) combines decades of observations of 65 millisecond pulsars from 7 radio telescopes. IPTA datasets shou…
Tackling artefacts in the timing of relativistic pulsar binaries: towards the SKA
Huanchen Hu, Nataliya K. Porayko, Willem van Straten +3
Common signal-processing approximations produce artefacts when timing pulsars in relativistic binary systems, especially edge-on systems with tight orbits, such as the Double Pulsa…
Periodicity search in the timing of the 25 millisecond pulsars from the second data release of the European Pulsar Timing Array
Iuliana Nitu, Michael Keith, David Champion +17
In this work, we investigated the presence of strictly periodic, as well as quasi-periodic signals, in the timing of the 25 millisecond pulsars from the EPTA DR2 dataset. This is e…
The NANOGrav 15 yr Data Set: Chromatic Gaussian Process Noise Models for Six Pulsars
Bjorn Larsen, Chiara M. F. Mingarelli, Jeffrey S. Hazboun +61
Pulsar timing arrays (PTAs) are designed to detect low-frequency gravitational waves (GWs). GWs induce achromatic signals in PTA data, meaning that the timing delays do not depend…
The Relativistic Spin Precession in the Compact Double Neutron Star System PSR~J1946+2052
Lingqi Meng, Weiwei Zhu, Michael Kramer +16
We observe systematic profile changes in the visible pulsar of the compact double neutron star system PSR~J1946+2052 using observations with the Five-hundred-meter Aperture Spheric…
A Gaussian-processes approach to fitting for time-variable spherical solar wind in pulsar timing data
Iuliana C. Niţu, Michael J. Keith, Caterina Tiburzi +26
Propagation effects are one of the main sources of noise in high-precision pulsar timing. For pulsars below an ecliptic latitude of , the ionised plasma in the solar wind…
High-altitude Magnetospheric Emissions from Two Pulsars
Mao Yuan, Weiwei Zhu, Michael Kramer +21
We discover three new weak pulse components in two known pulsars, one in PSR J0304+1932 and two in PSR J1518+4904. These components are emitted about half way between the main emis…
