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…
Mitigating the Timing Impact of Anomalous Pulse Profile Shape Variability in PSR J1713+0747 with Gaussian Component Modeling
Shania A. Nichols, Michael T. Lam, Gabriella Agazie +31
The paper presents a Gaussian component modeling technique to track and correct sudden pulse‑shape changes in the millisecond pulsar PSR J1713+0747, preserving high‑precision timin…
Exploring the Galactic plasma with pulsars in the SKA Era
Caterina Tiburzi, M. T. Lam, D. J. Reardon +17
The paper reviews how pulsar observations are used to probe the ionised plasma of the Milky Way, including electron density, turbulence, scattering, and magnetic fields, and discus…
The NANOGrav 15 yr Data Set: Impacts of Customized Chromatic Noise Models on Gravitational Wave Analyses
Nikita Agarwal, Gabriella Agazie, Alessandra Amosso +120
We report updated nHz gravitational wave (GW) significance, characterization, and interpretations using the customized chromatic-noise models (CNMs) developed in Larsen, Baier et a…
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…
