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…
A Square Kilometre Array Pulsar Census
E. F. Keane, V. Graber, L. Levin +7
Most of the pulsar science case with the Square Kilometre Array (SKA) depends on long-term precision timing of a large number of pulsars, as well as their astrometric measurements…
Pulsar Backend for 21 CentiMeter Array: Implementation of Data Acquisition and Initial Results
Yukai Zhou, Junhua Gu, Mengyao Xue +8
We implemented a data acquisition system for 21 CentiMeter Array (21CMA), enabling baseband observations targeting pulsars and fast radio bursts. Based on the Radio Frequency Syste…

E. F. Keane, V. Graber, L. Levin +8
Most of the pulsar science case with the Square Kilometre Array (SKA) depends on long-term precision pulsar timing of a large number of pulsars, as well as astrometric measurements…
Improving pulsar search efficiency in next-generation pulsar surveys with artificial intelligence
Qiuyang Fu, Mengyao Xue, Weiwei Zhu +12
Pulsar searching with next-generation radio telescopes requires efficiently sifting through millions of candidates generated by search pipelines to identify the most promising ones…
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…
