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…

Probing the magnetic field of a coronal mass ejection with PSR J1022+1001

El Mehdi Zahraoui, Hannah T. Rüdisser, Golam M. Shaifullah +24

We investigate whether low-frequency pulsar observations can provide LoS magnetic field estimates and whether these are consistent with synthetic LoS signatures extracted from a th…

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…

Source location and evolution of a multi-lane type II radio burst

P. Zucca, P. Zhang, K. Kozarev +8

Shocks in the solar corona can accelerate electrons that in turn generate radio emission known as type II radio bursts. The characteristics and morphology of these radio bursts in…

A parametric study of solar wind properties and composition using fluid and kinetic solar wind models

Paul Lomazzi, Alexis P. Rouillard, Michael A. Lavarra +7

The physical processes in the solar corona that shape the solar wind remain an active research topic. Modeling efforts have shown that energy and plasma exchanges near the transiti…
