Probing Variations in Earth's Ionosphere Using Pulsars

Yanqing Cai, Ziwei Wu, Weiwei Zhu +24

We present high cadence 10-minute rotation measure (RM) monitoring of PSR~J0814+7429 using the LOw-Frequency ARray, aiming to probe ionospheric variability along the pulsar line of…

Pulsar scintillation studies with LOFAR III. Annual variations in PSR~J08147429

Yanqing Cai, Ziwei Wu, Weiwei Zhu +27

The interstellar scintillation observed in radio pulsars arises from interference between electromagnetic waves scattered by electron density fluctuations in the turbulent interste…

Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data

F. Iraci, A. Chalumeau, C. Tiburzi +46

Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…

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…

The impact of Solar wind variability on pulsar timing

C. Tiburzi, G. M. Shaifullah, C. G. Bassa +22

High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are varia…

Dispersion measure variability for 36 millisecond pulsars at 150MHz with LOFAR

J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +19

Radio pulses from pulsars are affected by plasma dispersion, which results in a frequency-dependent propagation delay. Variations in the magnitude of this effect lead to an additio…
